    Appeals from the United States District Court
    for the Southern District of Texas
    Before SMITH, WIENER, and WILLETT, Circuit Judges.
    DON R. WILLETT, Circuit Judge:
    Under Aetna’s insurance plans, patients are responsible for a portion of
    their bills. That is not to say insurance companies are off the hook: They cover
    the remainder. But how much is Aetna obligated to pay for medical services
    provided to its members by an out-of-network hospital?
    Houston medical services provider North Cypress Medical Center
    Operating Co., Ltd. and North Cypress Medical Center Operating Co. GP, LLC
    (collectively “NCMC”) alleged Aetna underpaid out-of-network providers like
    NCMC in violation of the Employee Retirement Income Security Act of 1974
    (“ERISA”) and Texas law.

    Aetna fired back—it counterclaimed, alleging NCMC fraudulently and
    negligently misrepresented its billing practices by routinely waiving patient
    responsibilities yet billing Aetna for the total out-of-network cost.
    The result was a stalemate—each party fared no better than when they
    filed their claims. The district court granted Aetna judgment as a matter of
    law on NCMC’s ERISA claims and granted NCMC judgment as a matter of law
    on Aetna’s fraud and negligent misrepresentation counterclaims. And a jury
    found in favor of Aetna on NCMC’s remaining state law claims.
    We AFFIRM in part and REVERSE in part and REMAND.
    I. BACKGROUND
    The Byzantine complexity of the United States health care “system” can
    bamboozle even the savviest of consumers. So perhaps some foundation is
    helpful. 1
    A.     Aetna’s Insurance Plans
    Aetna is a managed care company that offers insurance, administrative
    services, and health care benefit plans, including employer-sponsored welfare
    benefit plans governed by ERISA, 29 U.S.C. § 101 et seq. As third-party plan
    administrator, it details its obligations and rights in “Administrative Service
    Agreements.” Each benefit plan’s terms of coverage describe the services
    covered and how Aetna calculates reimbursement rates.
    Plans can be, and commonly are, sponsored by employers. When that is
    the case, plans generally fall under one of two categories: “fully insured” or
    “self-funded.” Under fully insured ERISA plans, Aetna acts as a direct insurer;
    it guarantees a fixed monthly premium for 12 months and bears the financial
    1  NCMC has already encountered claims akin to those brought before us in this case.
    In fact, the claims here share substantially similar facts to those described in North Cypress
    Medical Center Operating Co., Ltd. v. Cigna Healthcare (NCMC I), 
    781 F.3d 182
    (5th Cir.
    2015).

    risk of paying claims. But under self-funded ERISA plans, Aetna acts only as
    a third-party administrator; the employer is responsible for paying claims and
    bearing the financial risk. Either way, Aetna plays a key role in its plans.
    Aetna administers the plans by processing and adjudicating claims and
    recovering overpayments. And employees contribute by paying monthly
    premiums. Ultimately, Aetna maintains discretion to construe the plan terms
    and determine available benefits.
    Aetna also organizes a network of providers and negotiates rates for
    health care services. In the Houston area, its network extends to 108 hospitals.
    In-network providers contract with Aetna to provide services at pre-arranged
    reimbursement rates in exchange for access to Aetna’s members as patients.
    Out-of-network providers do not; they have no contract with Aetna and instead
    set their own fees for services. When members seek treatment from either
    provider, they are often still responsible for copayments, deductibles, or co-
    insurance.
    So Aetna members have a choice—they can seek treatment from medical
    providers that are either inside or outside Aetna’s network. But this choice
    comes with strings attached; members may pay more for out-of-network
    providers. 2 This arrangement, Aetna says, helps control medical costs. In
    essence, incentivizing its members to seek medical treatment from in-network
    providers at pre-negotiated rates results in predictable, manageable expenses.
    B.    The Claims Process
    When Aetna members seek medical services from a provider, the
    provider then looks to Aetna to reimburse a portion of the expense. Service
    2  For example, under some plans, once a member satisfies the deductible, the
    member’s co-insurance for in-network providers is 80% (the plan paying 80% and the member
    paying 20%). But for an out-of-network provider, the member faces a higher deductible and
    a greater co-insurance burden (the plan paying 50% and the member paying 50%).

    No. 16-20674
    providers submit their claims to Aetna using standard “UB-04” forms. On that
    form, providers use a standardized code, called “Current Procedural
    Terminology” (“CPT”), to show what services they provided. Aetna uses these
    codes to determine how much of the claim is covered by its plans. To patients,
    this process is a black box: CPT codes go in, Aetna’s payment comes out.
    Patients do not know what they owe a provider for medical services until Aetna
    adjudicates the claim.
    Once Aetna determines a service is covered, it determines the “allowed
    amount.” Ultimately, Aetna does not pay the claim at face value; it pays only
    this allowed amount. Aetna retains discretion to determine the allowed
    amount. Plans allow Aetna to set the allowed amount for out-of-network claims
    based on the “usual, customary, and reasonable” (“UCR”) rate or in proportion
    to Centers for Medicare/Medicaid Services (“CMS”) rates. The UCR is divorced
    from what a provider bills. In this case, the allowed amount was treated as the
    UCR rate, even if plans may have provided for a different calculation.
    For its self-funded plans, Aetna has another option. It can process out-
    of-network claims through its National Advantage Program (“NAP”). NAP is a
    network of multiple entities, including Global Claims Services (“GCS”), a
    wholly owned Aetna subsidiary, and Multi-Plan, a third-party “rental” or
    “wrapper” network. GCS negotiates with out-of-network providers to price
    claims on a claim by claim basis. And Multi-Plan contracts with out-of-network
    providers and payors like Aetna to create a supplementary network, allowing
    for mass-negotiated repricing. Both entities discount a provider’s billed
    amount to determine the allowed amount.
    C.    NCMC and its Billing Practices
    NCMC, a physician-owned, full-service hospital, opened in Houston in
    January 2007. It offers a plethora of medical services you would expect from a
    full-service hospital—emergency room, surgery center, oncology unit,
    4
    Case: 16-20674       Document: 00514579998          Page: 5     Date Filed: 07/31/2018
    No. 16-20674
    pediatrics unit. NCMC granted ownership interests to physicians, and sought
    patient-referrals from its physician owners. Some of those physicians were
    under contract with Aetna to provide in-network care to patients through
    separate practices. Over 500 physicians have admission privileges at NCMC,
    and about 140 have an ownership stake.
    NCMC treats thousands of patients, including Aetna members, but it
    does not offer in-network care with Aetna. 3 Before it opened, NCMC
    unsuccessfully applied to be an Aetna participating provider. As a result,
    NCMC lacks a participating provider agreement with Aetna dictating
    reimbursement rates for services provided to Aetna members. After it was
    denied, NCMC informed Aetna it would operate as an out-of-network facility.
    Proving itself an able market competitor, NCMC offered a “prompt pay
    discount” program to patients. NCMC insists this program was not publicly
    advertised, and the discount applied only to elective procedures. Out-of-
    network patients were first notified of the discount at registration—they were
    assured they would pay no more than they would at an in-network facility.
    This hooked patients on NCMC.
    This program permitted out-of-network patients to discount their co-
    insurance obligation if they paid their bill within 120 days. 4 Ordinarily, NCMC
    calculates the total cost of care based on its master list of charges called the
    “Chargemaster.” 5 Without the discount, an Aetna patient may be responsible
    the cost of services at NCMC as an out-of-network facility, sometimes 50% of
    the total cost.
    3  NCMC is currently in-network with other insurance providers such as Blue Cross,
    United Healthcare, and Cigna.
    4 See NCMC 
    I, 781 F.3d at 188
    .
    5 A “Chargemaster” is a list of charges for goods and services that a hospital will bill
    its patients. For example, the list may include charges for “supplies, pharmacy, ancillary
    charges, lab charges, [or] radiology.” Chargemaster rates vary among medical facilities.
    5
    Case: 16-20674       Document: 00514579998          Page: 6     Date Filed: 07/31/2018
    No. 16-20674
    Rather than bill patients for the full out-of-network rate, NCMC
    calculated a much lower amount under its prompt pay discount. NCMC first
    calculated a patient’s in-network cost based on information provided by Aetna.
    NCMC estimated the in-network price at 125% of the Medicare rate. Then
    NCMC collected only the patient’s responsibility under the in-network co-
    insurance rate rather than the out-of-network rate. 6 If the patient paid that
    amount within 120 days, NCMC discounted the remaining balance. Otherwise,
    NCMC reversed the discount and billed the patient for her full responsibility.
    NCMC believed that by reducing the total amount owed in this fashion, the
    discount incentivized patients to—as the name implies—promptly pay their
    bills.
    Yet the amount NCMC reported to Aetna remained unchanged. NCMC
    submitted its UB-04 forms just like it would for any insurer. NCMC calculated
    its “Total Charges” in Box 47 of the claim form based on its Chargemaster
    prices, excluding its prompt-pay-discount formula. In other words, the forms
    did not otherwise report what amount NCMC billed out-of-network patients.
    But they did note a “prompt pay discount” in Box 80 of the claim forms, which
    provided a space for “Remarks.”
    NCMC submitted over 44,000 forms this way between 2009 and 2013.
    Aetna processed 90% of NCMC’s claims from self-funded plans through NAP
    between 2007 and 2012. In doing so, Aetna relied on GCS and Multi-Plan to
    negotiate “Repricing Agreements” to determine the allowable amounts. These
    6See 
    id. For example,
    NCMC charged an Aetna member for services costing
    $28,769.50 based on its Chargemaster. Because NCMC is an out-of-network provider, this
    member would have been responsible for an out-of-network deductible of $1,600, plus the
    50% co-insurance, capped at $6,000, for a total of $7,600. But rather than bill the patient for
    the full $28,769.50 and collect $7,600, NCMC would bill the patient $4,554.54, the estimated
    in-network price, instead of the $28,769.50 listed on its Chargemaster. As a result, NCMC
    would collect only $1,262.91: a $440 in-network deductible plus 20% in-network co-insurance
    on the remaining charge.

    No. 16-20674
    agreements paid NCMC’s claims more quickly, but at a discounted rate. The
    discounted charges were then considered the “allowed” charge. In a sense, this
    process formed a symbiotic relationship between Aetna and NCMC; by
    processing claims this way, Aetna collected a “savings fee” from the employer-
    sponsor’s account.
    D.    Aetna’s Response
    Aetna was, and remains, skeptical of NCMC’s discount program.
    NCMC informed Aetna about its prompt pay discount early and often.
    Between January 2007 and April 2009, NCMC sent monthly letters to Aetna
    advising it of the prompt pay discount. The letters explained that Aetna’s
    members “will be eligible to participate in the NCMC Prompt Payment Out-of-
    Network Discount Policy on patients[’] responsibility amounts for services and
    items rendered.”
    Aetna responded. In January 2007, Aetna wrote that it “appreciates the
    courtesy” NCMC offered to Aetna members. But it also warned NCMC of its
    obligations under Texas Insurance Code § 1204.055; Aetna worried NCMC’s
    discount was a “fee-forgiving” discount in violation of the Code.
    Yet NCMC was relentless in keeping Aetna up to speed. Even after it
    received Aetna’s response, NCMC continued to send its monthly letters. Once
    again, Aetna responded in April 2009, reiterating its appreciation and again
    reminding NCMC of its obligations under Texas Insurance Code § 1204.055.
    Aetna also prompted NCMC that members must be responsible for their out-
    of-network benefits. Needless to say, the discount raised some red flags.
    So Aetna investigated NCMC after it first received notice of the discount.
    In a November 2007 letter, Aetna accused NCMC of “routinely waiv[ing]
    deductible and co-insurance and the out-of-network penalty for which our
    members are normally responsible.” NCMC denied it waived patient co-
    payment amounts, but it admitted to the prompt pay discount. The discount,
    7
    Case: 16-20674   Document: 00514579998    Page: 8     Date Filed: 07/31/2018
    No. 16-20674
    according to NCMC, motivated prompt settlement of accounts. Apparently
    satisfied, Aetna closed its investigation and noted that NCMC did not “waive
    deductibles and co-insurance” or any co-pay amounts.
    Still, Aetna’s comprehensive efforts to get to the bottom of NCMC’s
    billing practices did not end there. In March 2008, Aetna reopened the
    investigation. That same month, Aetna’s Special Investigations Unit (“SIU”)
    apparently confirmed NCMC’s discount involved patient’s paying in-network
    responsibilities. Yet Aetna’s SIU once again cleared NCMC, finding that “it
    does not appear that North Cypress Medical Center routinely waives the out-
    of-network penalty nor forgives co-insurance.” Even so, Aetna’s SIU continued
    the investigation over a six-year period, flagging NCMC claims to manually
    scrutinize invoices for fraudulent waiver of patient-responsibility amounts.
    Despite this added scrutiny, Aetna never denied an NCMC claim for fee-
    forgiveness, and it never found evidence of fraud.
    Aetna was still worried that NCMC’s submitted claims “greatly exceeded
    those of other local providers.” In August 2012, Aetna dismissed NCMC from
    the NAP claims process and began adjudicating its claims in-house using the
    UCR under the terms of its health plans rather than the negotiated rate
    determined by NAP’s repricing agreements with NCMC. NCMC believes this
    caused a drastic reduction in the payment of claims submitted to Aetna.
    E.    The District Court Proceedings
    On February 12, 2013, NCMC sued Aetna. NCMC alleged Aetna violated
    ERISA and Texas law by intentionally under-paying out-of-network providers
    like NCMC. It argued that Aetna, as an out-of-network provider, was not
    properly processing NCMC’s claims under its plan terms or making a proper
    determination of the UCR.
    Aetna   counterclaimed,    alleging   common       law   fraud,   negligent
    misrepresentation related to NCMC’s pricing, and unjust enrichment in
    8
    Case: 16-20674    Document: 00514579998      Page: 9   Date Filed: 07/31/2018
    No. 16-20674
    violation of Texas law. Aetna moved to amend its counterclaims on January
    12, 2015 to add claims related to NCMC’s kickbacks for referring physicians
    and unjust enrichment, which the district court denied.
    The district court bifurcated the claims for jury trial.
    First, the court held a five-day bench trial on NCMC’s ERISA
    § 502(a)(1)(B) claim. NCMC argued that Aetna failed to pay under the terms
    of its plans. Aetna moved for judgment as a matter of law under Rule 52(c),
    arguing that the assignment of patient rights to NCMC was obtained using
    illegal means: the prompt pay discount. The court granted Aetna’s motion,
    finding no evidence Aetna (1) abused its discretion in processing claims;
    (2) failed to comply with plan terms; or (3) otherwise underpaid NCMC on any
    claim. But the court treated NCMC’s discount as lawful, and it found that
    NCMC advised payors about its program. The court also determined that
    NCMC was not entitled access to Aetna’s database of claims to establish
    damages. The court therefore dismissed NCMC’s ERISA claim.
    Next, the court held a three-week jury trial on both parties’ remaining
    state-law claims. At trial, Aetna’s damages expert also testified that Aetna
    would have paid over $100 million less, had it known the full details of NCMC’s
    “fraudulent scheme.” Aetna also offered evidence NCMC compensated
    physicians for patient referrals. Aetna argued that this evidence showed the
    full nature of NCMC’s scheme, motive, and fraudulent intent. The court
    rejected Aetna’s offer of proof on this matter, finding evidence of NCMC’s
    compensation to physicians both irrelevant and prejudicial.
    At the close of evidence, NCMC moved for judgment as a matter of law
    under Rule 50(a)(1) on Aetna’s fraud and negligent misrepresentation claims.
    The district court granted NCMC’s motion; it found no false information on
    NCMC’s UB-04 forms. The court also explained that NCMC lacked knowledge
    of any statement’s falsity, and NCMC did not intend for Aetna to act on any of
    9
    Case: 16-20674   Document: 00514579998     Page: 10    Date Filed: 07/31/2018
    No. 16-20674
    its statements. Additionally, the court held that Aetna was not justified in
    relying on NCMC’s statements because Aetna conducted its own internal
    investigations, had notice of NCMC’s discount program, and provided no
    evidence that it paid more than the UCR, which Aetna had discretion to
    determine. Finally, the court found no evidence of damages—the court rejected
    Aetna’s damages expert as biased and not reliable as a matter of law.
    The court then sent NCMC’s state-law claims to the jury, which returned
    a verdict in favor of Aetna. The district court entered judgment denying relief
    to both parties. NCMC moved for attorney fees based on the costs of defending
    Aetna’s counterclaim and prosecuting its affirmative claims. The court denied
    NCMC’s motion.
    Aetna appeals, and NCMC cross-appeals.
    II. AETNA’S APPEAL
    On appeal, Aetna challenges the district court’s ruling in four respects.
    First, Aetna maintains it sufficiently showed all the elements of its fraud
    claim, and it at least showed that NCMC negligently misrepresented its billing
    practices. Thus, Aetna contends, the district court erred in granting NCMC
    judgment as a matter of law. Second, Aetna argues that the district court erred
    in excluding its proffered evidence. It believes its expert, excluded as biased
    and unreliable, was crucial to establishing injury on its fraud and negligent
    misrepresentation claims. Aetna also maintains the district court erred in
    excluding “evidence of NCMC’s kickbacks to physicians.” Finally, Aetna
    challenges the district court’s denial of leave to amend.
    A.     Aetna’s Fraud and Negligent Misrepresentation Claims
    The district court granted NCMC’s Rule 50 motion for judgment as a
    matter of law on Aetna’s fraud and negligent misrepresentation claims. This
    court reviews a district court’s ruling on a motion for judgment as a matter of
    10
    Case: 16-20674       Document: 00514579998          Page: 11     Date Filed: 07/31/2018
    No. 16-20674
    law de novo, applying the same standard as the district court. 7 Rule 50 entitles
    a movant to judgment as a matter of law when “a party has been fully heard
    on an issue . . . and the court finds that a reasonable jury would not have a
    legally sufficient evidentiary basis to find for the party on that issue.” 8
    In order to survive a Rule 50 motion, “the party opposing the motion
    must at least establish a conflict in substantial evidence on each essential
    element of their claim.” 9 “Substantial evidence is more than a scintilla, less
    than a preponderance, and is such relevant evidence as a reasonable mind
    might accept as adequate to support a conclusion.” 10 Evidence is legally
    insufficient “where the facts and inferences point so strongly and
    overwhelmingly in favor of the moving party that reasonable jurors could not
    arrive at a contrary verdict.” 11 Evidence is examined as a whole and all
    inferences are drawn in favor of the non-moving party. 12 “[T]he court may not
    make credibility determinations or weigh the evidence, as those are jury
    functions.” 13
    Under Texas law, the elements of fraud are:
    (1) that a material representation was made; (2) the
    representation was false; (3) when the representation was made,
    the speaker knew it was false or made it recklessly without any
    knowledge of the truth and as a positive assertion; (4) the speaker
    made the representation with the intent that the other party

    “Fraud can also occur through non-disclosure of material facts when the non-
    disclosing party had a duty to disclose.” 15 “Material” means “a reasonable
    person would attach importance to and would be induced to act on the
    information in determining his choice of actions in the transaction in
    question.” 16    The     primary      difference     between       fraud    and     negligent
    misrepresentation 17 is that a “negligent misrepresentation claim does not
    require an actual intent to defraud, only that . . . the party making the false
    statement acted negligently in doing so.” 18
    The district court found that Aetna failed to establish any element of
    fraud. More importantly, the district court found no evidence “from which [it]
    can infer or a jury might infer that Aetna justifiably relied on any information
    supplied to North Cypress.” We agree. Assuming without deciding that Aetna
    established the other elements of fraud, we find Aetna could not have
    justifiably relied on any representation by NCMC.

    17 The elements of negligent misrepresentation are:
    (1) the representation is made by a defendant in the course of his business, or
    in a transaction in which he has a pecuniary interest; (2) the defendant
    supplies “false information” for the guidance of others in their business; (3) the
    defendant did not exercise reasonable care or competence in obtaining or

    justifiably relying on the representation.

    “Both fraud and negligent misrepresentation require that the plaintiff
    show actual and justifiable reliance.” 19 Reliance is not shown if, based on “a
    fraud plaintiff’s individual characteristics, abilities, and appreciation of facts
    and circumstances at or before the time of the alleged fraud[,] it is extremely
    unlikely that there is actual reliance on the plaintiff’s part.” 20 A person “may
    not justifiably rely on a representation if there are red flags indicating such
    reliance is unwarranted.” 21
    Justifiable reliance “usually presents a question of fact,” but “the
    element can be negated as a matter of law when circumstances exist under
    which reliance cannot be justified.” 22 For example, in a recent case decided by
    the Texas Supreme Court, Orca Assets, a company formed by an experienced
    oil-and-gas businessman to acquire unleased acreage, signed an oil-and-gas
    lease for land that turned out to be already leased. 23 Orca claimed it justifiably
    relied on statements by JPMorgan, the lessor’s agent, that the land was open. 24
    But the parties negotiated a written letter of intent that assigned Orca the risk
    of failure of title, directly contradicting those earlier representations. 25 The
    court thus concluded that multiple “red flags,” plus Orca’s sophistication in the
    oil-and-gas industry, negated any justifiable reliance Orca had on any alleged
    misrepresentations. 26

    We have also held that a company’s own investigation of the facts may
    negate “any reasonable reliance upon the supposed misrepresentations.” 27 In
    Highland Crusader Offshore Partners LP v. LifeCare Holdings, Inc., Highland
    alleged LifeCare and JPMorgan were liable for fraud in representing that all
    lenders were offered 75 basis points (“bps”) when some were offered 125. 28 But
    Highland had collected information on other lenders and learned that LifeCare
    and JP Morgan made offers of 125 bps to other lenders before it accepted its
    offer for 75. 29 Thus, this court found that “no reasonable jury could find that
    Highland justifiably relied on” the misrepresentation because of “its own
    investigation of the facts.” 30
    Here, red flags, Aetna’s independent investigation, and Aetna’s
    sophistication negate any justifiable reliance Aetna had on NCMC’s alleged
    misrepresentations. Aetna contends that it did not receive information about
    the discount, but evidence says otherwise. Within three months of NCMC
    opening, Aetna investigated NCMC’s billing practices. Aetna’s SIU conducted
    a six-year investigation and flagged NCMC claims to manually scrutinize
    invoices for fraudulent waiver of patient-responsibility amounts. Aetna also
    engaged in repeated audits of NCMC’s Chargemaster. And it even filed
    protests with state agencies responsible for hospital facility oversight.
    Ultimately, Aetna’s investigations resulted in no finding of fraud. More
    importantly, as early as March 2008, Aetna knew the exact information it

    alleges NCMC failed to disclose: the rate at which patients paid NCMC for
    services. Aetna was thus fully aware of the discount.
    Aetna’s reliance on any alleged misrepresentation by NCMC was not
    justifiable. Almost immediately after NCMC notified Aetna of its prompt pay
    discount, Aetna began investigating. Its investigation revealed NCMC’s billing
    practices. Yet Aetna continued to pay claims marked with the prompt pay
    discount moniker. Aetna failed to establish a conflict in substantial evidence
    on this element of its fraud and negligent representation claims.
    B.     Aetna’s Excluded Evidence
    Aetna argues the district court erred in making two evidentiary
    decisions: rejecting its damages expert and excluding evidence of NCMC’s
    compensation to physicians for patient referrals. This court reviews
    evidentiary decisions for abuse of discretion. 31 “A trial court abuses its
    discretion when its ruling is based on an erroneous view of the law or a clearly
    erroneous assessment of the evidence.” 32 Even if the court abused its
    discretion, “the error is reviewed under the harmless error doctrine.” 33 An
    evidentiary ruling is reversible only if it affected a party’s substantial rights. 34
    Aetna first argues the district court erred in finding its expert biased and
    unreliable. Aetna says this expert was crucial to establishing injury on its
    fraud and negligent misrepresentation claims. Because we affirm the court’s

    No. 16-20674
    judgment as a matter of law in favor of NCMC on other grounds, any error was
    harmless. 35
    Next, Aetna argues the district court erred by excluding “evidence of
    NCMC’s kickbacks to physicians.” The court found this evidence was
    “irrelevant to whether North Cypress fraudulently billed Aetna” and the
    potential prejudice outweighed any probative value. We agree.
    Evidence is relevant if “it has any tendency to make a fact more or less
    probable than it would be without the evidence” and “the fact is of consequence
    in determining the action.” 36 Irrelevant evidence is not admissible. 37 A district
    court may “exclude relevant evidence if its probative value is substantially
    outweighed by a danger of . . . unfair prejudice . . . .” 38 “A trial court’s ruling on
    admissibility under Rule 403’s balancing test will not be overturned on appeal
    absent a clear abuse of discretion.” 39
    In order to show abuse of discretion, Aetna must identify how its
    excluded evidence relates to a material misrepresentation. 40
    On appeal, Aetna argues it should “have been permitted to provide a
    complete, unsanitized picture of how and why NCMC’s fraud occurred.” This
    evidence allegedly demonstrated NCMC’s scheme, motive, and fraudulent
    intent.
    Aetna is correct that it is ordinarily not unfairly prejudicial for a jury “to
    see the entire scheme and its results.” 41 And this court errs on the side of

    admissibility of evidence in fraud cases because a jury must often infer
    intent. 42 But here, Aetna has not shown how excluded evidence of physician
    compensation relates to any of NCMC’s alleged material misrepresentations.
    NCMC may have intended to build its business by incentivizing physicians to
    make patient referrals, but Aetna only alleges fraud based on what NCMC
    charged its patients and subsequently reported to Aetna.
    Physician compensation is less relevant to these allegations. The UB-04
    claim form did not require NCMC to disclose physician compensation. In fact,
    Aetna concedes that payments to physicians were part of a different fraudulent
    scheme. Aetna notes that physician shares “were a vehicle to illegally and
    fraudulently pay for patients referred to [NCMC].” Aetna also argued “[t]his
    evidence shows . . . the physician-owners’ motive.” But Aetna never alleges that
    referring physicians advertised NCMC’s prompt pay discount when referring
    patients to NCMC. 43 In fact, NCMC insists it did not publicly advertise its
    discount program. NCMC’s payments might explain why physicians referred
    patients to NCMC, or indicate that NCMC violated the terms of Aetna’s
    agreements, but they do not tend to explain NCMC’s motive in adopting the
    prompt pay discount. And these payments do not support allegations that
    NCMC misrepresented its billing practices.
    To sum up, any error in excluding Aetna’s damages expert was harmless,
    and we cannot say the district court abused its discretion in excluding evidence
    of physician compensation.
    because the fact that “a representation had been put in writing in the agreement”
    strengthened the plaintiff’s case, and “the debts and to whom they were owed were a
    legitimate inquiry in the suit”).

    578 F.2d 629
    , 632–33 (5th Cir. 1978).
    43 Aetna’s arguments to the district court also lacked any connection to the alleged
    fraudulent overbilling. For example, it argued that the physician shares incentivized
    physicians to refer prospective patients to NCMC, and only “[a]fter it got those patients,
    [NCMC] misrepresented the total charges for their care.”

    C.     Aetna’s Motion for Leave to Amend
    Aetna next argues that the district court erred in denying it leave to
    amend its counterclaims. We review denial of leave to amend for abuse of
    discretion. 44 Under the liberal pleading presumption, discretion “may be
    misleading, because [Rule] 15(a) evinces a bias in favor of granting leave to
    amend.” 45 Rule 15(a) requires a trial court to “freely give leave when justice so
    requires.” 46 Leave to amend is not automatic, but a district court needs “a
    ‘substantial reason’ to deny a party’s request for leave to amend.” 47 Leave to
    amend may be denied for “undue delay, bad faith or dilatory motive on the part
    of the movant, repeated failures to cure deficiencies by amendments previously
    allowed, undue prejudice to the opposing party . . . , and futility of the
    amendment.” 48 In reviewing the timeliness of a motion to amend, delay alone
    is insufficient: “The delay must be undue, i.e., it must prejudice the nonmoving
    party or impose unwarranted burdens on the court.” 49 For futility, “[a]n
    amendment is futile if it would fail to survive a Rule 12(b)(6) motion.” 50
    “In light of the presumption in favor of allowing pleading amendments,
    courts of appeals routinely hold that a district court’s failure to provide an
    adequate explanation to support its denial of leave to amend justifies
    reversal.” 51 This court has a “strong preference for explicit reasons” 52 in
    denying leave to amend, and we have “expressly stated that motions to amend

    should be freely granted and that a district court’s failure to explain its reasons
    for denying the motion typically warrants reversal.” 53 But if “justification for
    the denial is readily apparent, a failure to explain is unfortunate but not fatal
    to affirmance if the record reflects ample and obvious grounds for denying leave
    to amend.” 54
    Aetna moved to amend its counterclaims after learning “additional
    details about NCMC’s scheme during discovery.” In its proposed amended
    complaint, Aetna added claims for unjust enrichment based on NCMC’s
    kickbacks to referring physicians, tortious interference, and breach of contract.
    Aetna also sought to add NCMC’s CEO, Robert Behar, as a defendant. NCMC
    opposed Aetna’s motion for leave to amend, arguing that Aetna’s amended
    counterclaims were frivolous because the statutes relied on by Aetna neither
    applied to NCMC nor provided a private cause of action. NCMC also contended,
    based on a scheduling order that indicated “None” as the deadline for the
    addition of new parties, that Aetna’s motion was “late.” The court summarily
    denied Aetna leave to amend.
    The summary denial was an abuse of discretion under the circumstances
    presented here.
    This was Aetna’s first attempt to amend. NCMC made only two
    arguments in opposition to Aetna’s motion: Amendment would be futile
    because Aetna’s claims were “frivolous,” and criticizing “the lateness of the
    filing.” But undue delay, such that NCMC would be prejudiced by Aetna’s
    proposed amendment, is not obvious. And futility is far from clear—both
    parties vigorously contest whether ERISA preempts Aetna’s proposed claims.
    Yet the district court denied leave to amend without examining these

    arguments or explaining its reasons. The district court should have granted
    leave to amend or, alternatively, explained its denial.
    Having concluded that the district court abused its discretion in denying
    Aetna leave to amend without providing reasons, we must now determine the
    appropriate remedy. 55 In Wiwa v. Royal Dutch Petroleum Co., a panel of this
    court analyzed the denial of a motion to quash or modify a subpoena. 56 There,
    the district court quashed a subpoena and denied a motion to compel without
    providing any explanation. 57 After finding that the court abused its discretion,
    the panel addressed how it should remedy the error. The parties proposed two
    paths of action: The court could either remand with instructions to grant the
    motion or remand with instructions to explain why it denied the motion to
    compel and quash the subpoena. 58
    But the panel adopted a third approach. It reasoned that the court “ha[s]
    the power to make such disposition of the case as justice may require.” 59
    Remanding the case would likely “be an exercise in futility” because it would
    unnecessarily prolong the dispute and the underlying litigation in another
    court. 60 Thus, in the interest of “judicial economy, the convenience to the
    parties, the likelihood of a subsequent appeal if the district court were to deny
    the discovery motion with reasons, and further delay” to litigation, the panel
    modified the subpoena and remanded for further proceedings. 61

    We follow the Wiwa court’s lead. Here too, we review denial of leave to
    amend for abuse of discretion. Ordinarily, a district court’s failure to explain
    its denial of leave to amend is an abuse of discretion justifying reversal. 62 But
    there is no indication this result is required. Where our case law does not
    dictate a particular remedy, we retain authority to “affirm, modify, vacate, set
    aside or reverse any . . . order of a court lawfully brought before it for review,
    and may remand the cause and direct the entry of such appropriate . . . order,
    or require such further proceedings to be had as may be just under the
    circumstances.” 63 In determining whether to remand for the district court to
    explain its denial we consider whether remand enhances the interests of
    judicial economy, the convenience of parties, the likelihood of subsequent
    appeal once the court explains its denial, and any further delay to related
    litigation. 64 Remanding to provide the district court with an opportunity to
    explain its denial is preferred. But if, under the circumstances, remanding is
    not practical or efficient, we may examine the record to determine whether
    denial of leave to amend is justified.
    Under the circumstances presented in this appeal, remanding would be
    “an exercise in futility.” There is a high likelihood of a subsequent appeal if the
    district court were to deny the motion for leave to amend with reasons. In this
    respect, remanding would diminish judicial economy; the same issue would
    return to us on a future appeal. And Aetna has already filed a separate suit
    alleging claims identical to those it sought to add to its counterclaims. 65 That

    2015) [hereinafter Behar litigation]. Aetna filed that suit on February 23, 2015, after the
    district court denied its motion for leave to amend. Because the claims Aetna filed were
    substantially similar to those in the instant suit, NCMC moved to dismiss, or in the
    alternative, transfer, based on the “first-to-file” rule. The district court denied NCMC’s

    litigation has been on hold, and remanding for further explanation would only
    further prolong the underlying litigation in that case. As a result, we examine
    whether the record supports denial of Aetna’s motion for leave to amend.
    We find Aetna’s motion was untimely in light of the procedural history
    of the case; the court’s denial of leave to amend was justified based on undue
    delay. 66 In Mayeaux, this court found that even though the plaintiff’s motion
    to amend was filed within the scheduling deadline, an “examination of the
    procedural history” led the panel to “a definite and firm conviction that
    [defendants] would have suffered undue prejudice” had the court allowed
    amendment. 67 The panel reasoned that the proposed amendments “pleaded a
    fundamentally different case with new causes of action and different parties.” 68
    The court further explained that when late amendments “involve new theories
    of recovery and impose additional discovery requirements, courts [of appeal]
    are less likely to find an abuse of discretion due to the prejudice involved.” 69
    The court thus found that the defendants would have been prejudiced by the
    delay and did not abuse its discretion in denying leave to amend.
    Here, Aetna filed its motion two years after the case began, four months
    before dispositive motions were due, and seven months before the close of
    discovery. 70 Aetna based its amended complaint on documents it received six
    months before its motion. Like the plaintiffs in Mayeaux, Aetna sought to add
    motion, reasoning that in denying Aetna leave to amend, Judge Hoyt “indicated that the
    claims . . . should not be considered” in the instant case, and dismissing Aetna’s case entirely
    “would deny Aetna any forum in which to present its claims.” The court instead issued a
    limited stay, reasoning that “many issues . . . may be resolved” by the instant suit.

    new claims and a new defendant to the litigation. 71 These new claims would
    have required NCMC to adopt an entirely new defense. The district court likely
    worried that Aetna’s delay would fundamentally change the nature of the
    case—prejudicing NCMC.
    The district court abused its discretion by denying Aetna leave to amend
    without providing reasons. Ordinarily, this justifies reversal. But here,
    remanding for an explanation would be impractical and inefficient. We find
    denial of leave to amend was warranted because Aetna’s counterclaims were
    untimely and unduly prejudicial to NCMC. 72
    This result does not foreclose Aetna’s ability to pursue its claims. Once
    this case is resolved, Aetna will be able to pursue its proposed additional claims
    in the Behar litigation.
    III. NCMC’S CROSS-APPEAL
    NCMC counter-appealed the district court’s evidentiary ruling denying
    access to Aetna’s “reimbursement methodology,” the grant of Aetna’s Rule 52(c)
    motion for judgment as a matter of law on NCMC’s ERISA claims, and the
    denial of attorney fees.
    A.     Access to Aetna’s Reimbursement Methodology
    NCMC first argues it was entitled to Aetna’s “methods to determine
    reimbursement rates under its ERISA plans.” Without this information,
    NCMC reasons that it could not establish injury. We disagree.
    71  Aetna sought to add Dr. Behar, NCMC’s CEO as a defendant, and it alleged new
    claims under RICO, 18 U.S.C. § 1962(c), tortious interference with in-network agreements,
    tortious interference with Healthcare benefit plans, and breach of contract.
    72 In so holding, we pretermit the discussion of whether denial could be justified based
    on futility. See 
    Mayeaux, 376 F.3d at 427
    –28 n.18. We also note that this opinion does not
    excuse district courts of their responsibility to provide reasons explaining decisions that we
    review for abuse of discretion. Without accompanying reasons, we are deprived of the district
    court’s reasoning and cannot exercise meaningful review.

    No. 16-20674
    A court’s decision to limit discovery is reviewed for abuse of discretion. 73
    A court abuses its discretion when a decision is based on an erroneous view of
    the law. 74 A trial court’s discovery ruling “should be reversed only in an
    ‘unusual and exceptional case.’” 75 Denial of a motion to compel is also reviewed
    for abuse of discretion. 76 A denial, “unaccompanied by reasons—either oral or
    written—may constitute an abuse of discretion.” 77 But this court will vacate a
    district court’s ruling only if “the abuse of discretion affected the substantial
    rights of the appellant.” 78 As appellant, NCMC bears the burden of showing
    abuse of discretion and prejudice. 79
    NCMC argues that without access to Aetna’s “reimbursement
    methodology,” it could not replicate the UCR to determine whether Aetna
    abused its discretion under its ERISA plans. NCMC’s appeal effectively
    challenges two rulings: the denial of NCMC’s March 2014 motion to compel
    disclosure of Aetna’s “fee schedules” and “reimbursement methodologies,” and
    the court’s conclusion in granting Aetna judgment under Rule 52(c) and
    holding that NCMC was not entitled to access Aetna’s database under ERISA.
    NCMC argues this information was relevant to establish damages, and it was
    “entitled to this information under ERISA,” 29 U.S.C. § 1024(b)(4).
    After granting NCMC’s motion to compel production, the district court
    denied NCMC’s subsequent motion to compel production of the same

    documents without providing reasons. Thus, the court facially erred. 80 So we
    consider whether the error was harmless. At first glance, NCMC’s argument
    regarding the harm of the error has some bite: Because Aetna’s plans
    reimburse providers based on the UCR, NCMC needed to know how Aetna
    determined the UCR to assess whether it was paid under the terms of Aetna’s
    plans. In other words, without this information, NCMC could not establish an
    ERISA violation. We disagree that the error harmed NCMC because Aetna
    provided methods it used to calculate its reimbursement rates.
    Any error in denying NCMC’s motion to compel was harmless.
    In June 2013, the court ordered Aetna to produce information regarding
    its “fee schedules” and “reimbursement methodologies.” Aetna produced all fee
    schedules it could identify, as well as other documents reflecting its
    methodologies for computing reimbursement rates. Yet in February 2014,
    NCMC again moved to compel production of additional fee schedules and
    databases used to calculate reimbursements. In response, Aetna identified fee
    schedules and methodologies it previously produced.
    After reviewing Aetna’s disclosure, we find Aetna largely produced the
    information NCMC requested—evidence enabling NCMC to determine
    whether Aetna underpaid reimbursements under its plan terms. Aetna’s plans
    require it to reimburse providers based on the “reasonable and customary”
    amount defined by the plan. This amount is the lesser of the customary charges
    for the region, the provider’s actual or usual charge, or the rate “Aetna
    determines to be appropriate” or reasonable. Aetna also produced documents
    reflecting methodologies for calculating reimbursement rates. 81 It disclosed
    how it calculated NCMC’s reimbursements after it removed NCMC from Multi-
    80  See 
    Wiwa, 392 F.3d at 817
    –19.
    81  In its response in opposition to NCMC’s motion to compel, Aetna specifically
    identified by Bates number responsive documents that it already produced.
    25
    Case: 16-20674       Document: 00514579998          Page: 26     Date Filed: 07/31/2018
    No. 16-20674
    Plan. 82 Aetna paid a rate at the 80th percentile for NCMC’s geographic region,
    and the policy defined the region and data source. And publicly available
    sources also provided the reasonable rate. NCMC had access to every plan at
    issue, but it has not identified a single claim where Aetna underpaid it under
    the terms of those plans.
    Plus, NCMC agreed with Aetna that producing the database would be
    impractical, yet it proposed no alternative way to access the underlying
    information. Even on appeal, NCMC only sought access to “reimbursement
    methodolog[ies]”—without specifying any particular document it sought or
    describing how Aetna’s disclosures were inadequate. It was not until NCMC’s
    reply brief that it named specific evidence. Although the district court did not
    offer any reasons, the court did not abuse its discretion in denying NCMC’s
    second motion to compel. 83
    NCMC also argues it was entitled to “information revealing Aetna’s
    methodology for calculating UCR reimbursement on out-of-network claims”
    under ERISA, 29 U.S.C. § 1024(b)(4). We disagree.
    ERISA requires a plan administrator, upon written request, to furnish
    plan documents to participants and beneficiaries, including “the latest updated
    summary, plan description, . . . trust agreement, contract, or other instruments
    under which the plan is established or operated.” 84 “Any administrator . . . who
    fails or refuses to comply with a request for any information” may be
    82  After Aetna removed NCMC from the Multi-Plan process, it processed NCMC’s
    claims using Truven Health Analytics Profile data for outpatient claims before June 2014
    and cost-to-charge ratios from the cost report NCMC submitted to Medicare for all other
    claims.
    83 See Taite v. City of Ft. Worth Tex., 681 F. App’x 307, 310 (5th Cir. 2017) (finding
    that the district court did not abuse its discretion in denying an appellant’s motion to compel
    where “[a] review of the [appellee’s] responses . . . demonstrate[d] that it produced the
    information [appellant] had requested to the extent that information was available”).

    Case: 16-20674      Document: 00514579998          Page: 27     Date Filed: 07/31/2018

    “personally liable to such participant or beneficiary.” 85 ERISA defines
    “administrator” as “the person specifically so designated” in the plan or “the
    plan sponsor” if no administrator is designated. 86
    NCMC invokes ERISA §§ 104(b)(4) & 502(c) as a basis for civil penalties.
    But here, Aetna is neither the designated administrator nor the sponsor of the
    plans at issue. Instead, Aetna “serves as the third-party administrator
    pursuant to various [agreements].” And the Fifth Circuit does not recognize a
    de facto administrator doctrine in the context of an insurance company
    involved in claims handling. 87 So Aetna is not subject to either ERISA’s
    disclosure requirement or the civil penalty under the circumstances here.
    B.     NCMC’s ERISA Claims
    At the close of the bench trial, the district court granted Aetna’s Rule
    52(c) motion for judgment as a matter of law on NCMC’s ERISA claims. It
    found “no evidence” Aetna abused its discretion in processing NCMC’s claims.
    NCMC argues that because it was denied access to Aetna’s reimbursement
    methodology, it could not show damages.
    “On appeal from a bench trial, this court review[s] the factual findings of
    the trial court for clear error and conclusions of law de novo,” applying the
    same standard as the district court. 88 Because the plans at issue grant Aetna
    discretionary authority to set the allowed amount or UCR, we apply the abuse
    of discretion standard. 89 Thus, if Aetna’s “decision is supported by substantial
    evidence and is not arbitrary and capricious, it must prevail.” 90

    NCMC       sought    benefits    under    the    plan      terms   under   ERISA
    § 502(a)(1)(B), arguing that it was underpaid after Aetna removed it from
    Multi-Plan. In order to assess its damages, NCMC compares what Aetna paid
    it following removal to the rate Aetna paid under Multi-Plan.
    ERISA aims to promote the interests of plan participants and their
    beneficiaries and to “protect contractually defined benefits.” 91 ERISA
    enshrines a patient’s right to the “full and fair review” of her claim. 92 As a
    result, § 502(a)(1)(B) permits a plan participant to sue to “recover benefits due
    to him under the terms of his plan, to enforce his rights under the terms of the
    plan, or to clarify his rights to future benefits under the terms of the plan.” 93
    Here, NCMC seeks to enforce its contractual rights to benefits under Aetna’s
    plan terms.
    To determine whether Aetna, as a third-party administrator, abused its
    discretion in construing a plan’s terms, we analyze its plan interpretation in
    two steps. 94 First, the court asks whether Aetna’s reading is “legally correct.” 95
    ERISA plans must be written to be understood by the average plan
    participant, 96 so plans “are interpreted in their ordinary and popular sense as
    would a person of average intelligence and experience.” 97 The “most important
    factor to consider” is whether Aetna’s “interpretation is consistent with a fair
    reading of the plan[s].” 98 If so, the inquiry ends, and there was no abuse of
    discretion. 99 Otherwise, the court “must then determine whether [Aetna’s]

    decision was an abuse of discretion.” 100 This court is “not confined to this test”
    and may “‘skip the first step if’ it ‘can more readily determine that the decision
    was not an abuse of discretion.’” 101
    Instead of comparing the plan terms to Aetna’s payments, NCMC argues
    it is entitled to 75% of NCMC’s billed charges, the amount Aetna historically
    allowed under Multi-Plan before August 2012. NCMC offered an estimate of
    Aetna’s underpayment based on that figure. The district court determined that
    Aetna had discretionary authority to determine the UCR, so NCMC had the
    burden to identify specific proof of underpayment. But NCMC did not identify
    specific claims for which it sought recovery; there was no evidence Aetna failed
    to make determinations under the terms of its plans.
    NCMC makes this same argument on appeal without identifying any
    claim Aetna allegedly underpaid. Aetna’s agreement with Multi-Plan provided
    for a fixed percentage of billed charges. But Aetna exercised its contractual
    right to stop processing NCMC’s claims through Multi-Plan because NCMC’s
    rates “greatly exceeded those of local providers.” Once Aetna removed NCMC
    from Multi-Plan, the terms of the Multi-Plan agreement did not apply. Aetna
    was required to apply the reasonable and customary rate. Aetna thus
    processed claims by applying the coverage formula under its health care plan
    terms. 102 Aetna never declined NCMC’s claims; it paid them according to the
    “reasonable and customary amount” as defined under the plan language.

    102 NCMC argues it could not establish damages because Aetna withheld its
    reimbursement methodology. 
    See supra
    Section IV.E.2.b. Aetna disclosed the formula it
    applied after NCMC was removed from Multi-Plan. For example, for outpatient claims
    processed before June 2014, Aetna’s formula calculated payment at the 80th percentile for
    NCMC’s geographic region. For other claims, Aetna applied the cost-to-charge ratio NCMC
    submitted to Medicare.

    No. 16-20674
    Aetna also produced all information needed to determine whether it complied
    with the terms of its plans, and NCMC had access to every plan at issue.
    The district court therefore did not err in granting Aetna’s Rule 52(c)
    motion for judgment as a matter of law.
    C.     Attorney Fees
    NCMC moved for attorney fees based on the costs it incurred in
    defending against Aetna’s counterclaim and prosecuting its affirmative claims.
    The court denied the motion.
    An award of attorney fees under ERISA is “purely discretionary” and is
    reviewed “only for an abuse of discretion.” 103 ERISA § 502(g)(1) provides a court
    with discretion to “allow a reasonable attorney’s fee and costs of action to either
    party.” 104 A claimant “must show ‘some degree of success on the merits’ before
    a court may award attorney’s fees.” 105 Success means “the court can fairly call
    the outcome of the litigation some success on the merits without conducting a
    lengthy inquiry into the question whether a particular party’s success was
    substantial or occurred on a central issue.” 106 In doing so, the court may, but
    is not required to, weigh five factors:
    (1) the degree of the opposing parties’ culpability or bad faith;
    (2) the ability of the opposing parties to satisfy an award of
    attorneys’ fees;
    (3) whether an award of attorneys’ fees against the opposing
    parties would deter other persons acting under similar
    circumstances;
    (4) whether the parties requesting attorneys’ fees sought to benefit
    all participants and beneficiaries of an ERISA plan or to resolve a
    significant legal question regarding ERISA itself; and

    (5) the relative merits of the parties’ positions. 107
    NCMC argues the district court abused its discretion because Aetna
    challenged how NCMC submitted its bills, and NCMC successfully defeated
    this challenge. We disagree.
    The district court also found that NCMC’s prompt pay discount was
    lawful, that NCMC properly executed its UB-04 forms, that NCMC is free to
    set its own fees and properly advised Aetna of its total charges, and that NCMC
    acquired assignments designating it as an ERISA beneficiary. Aetna counters
    that NCMC is not entitled to fees because its counterclaims were state law
    claims, not ERISA claims. And NCMC only claims victory on “favorable
    findings” by the court rather than its ERISA claims, and even still, NCMC’s
    claims of victory ring hollow.
    The district court summarily denied NCMC’s motion for attorney fees.
    “A district court must explain its decision to deny fees, and if, as here, it fails
    to give any explanation, we must remand.” 108 Without further discussion, “we
    are deprived of the benefit of the district court’s reasoning and thus cannot
    conduct the required review.” 109 As a result, we vacate the order denying
    attorney fees and remand for an explanation. 110

    (“Although an award of attorney’s fees, like an award of costs, is committed to the discretion

    reasons for its decisions . . . otherwise we cannot exercise meaningful review.” (internal

    No. 16-20674
    For the above reasons, we AFFIRM the district court’s orders granting
    NCMC judgment as a matter of law on Aetna’s fraud and negligent
    misrepresentation claims and granting Aetna judgment as a matter of law on
    NCMC’s ERISA claim. We also AFFIRM the court’s denial of Aetna’s motion
    for leave to amend, as well as the district court’s evidentiary rulings.
    We VACATE the district court’s denial of NCMC’s motion for attorney
    fees and issue a limited REMAND for an explanation.
