    No. 19CA1039, Morris v. ICAO — Labor and Industry —
    Workers’ Compensation — Division-Sponsored Independent
    Medical Evaluation
    In this workers’ compensation case, the division holds that a
    DIME’s "findings and determinations," as contemplated by section
    8-42-107.2(4)(c), do not include a DIME’s recommendation to
    convert a scheduled impairment to a whole person impairment, and
    that the insurer and employer do not forfeit their right to challenge
    a claimant's request to convert his impairment even if the insurer
    and employer do not request a hearing on the issue of conversion
    within twenty days of the DIME report.

    VI, § 5(3), and § 24-51-1105, C.R.S. 2019.
    ¶1    In this workers’ compensation action, claimant, Zachary
    Morris, seeks review of a final order of the Industrial Claim Appeals
    Office (Panel), which affirmed the order of an administrative law
    judge (ALJ) denying and dismissing his request for whole person
    permanent partial disability (PPD) benefits. We hold that the
    “findings and determinations” of a division sponsored independent
    medical examination (DIME), as contemplated by section 8-42-
    107.2(4)(c), C.R.S. 2019, do not include a DIME’s recommendation
    to convert a scheduled impairment to a whole person impairment,
    and that the insurer and employer do not forfeit their right to
    challenge a claimant’s request to convert his impairment even if the
    insurer and employer do not request a hearing on the issue of
    conversion within twenty days of the DIME report. Therefore, we
    affirm.
    I.    Background
    ¶2    Claimant sustained an admitted work-related injury in April
    2015, when he slipped on scaffolding. He was treated for his
    injuries and diagnosed with a left ankle sprain. Several months
    after his fall, claimant also reported pain in his lower back.
    Claimant’s treating physician, Dr. Albert Hattem, placed him at
    1
    maximum medical improvement (MMI) with no impairment in
    March 2016. Because he disagreed with the determination that he
    had no permanent impairment, claimant requested a DIME.
    ¶3    The DIME physician, Dr. J. Stephen Gray, agreed with Dr.
    Hattem that claimant reached MMI in March 2016, but assigned
    claimant a 14% impairment rating for his left lower extremity,
    which Dr. Gray noted could be converted to a 6% impairment of the
    whole person. Dr. Gray also recommended that claimant receive
    ongoing maintenance medical care.
    ¶4    In May 2017, claimant’s employer, Olson Heating & Plumbing
    Co., and its insurer, Pinnacol Assurance (collectively, employer),
    filed a final admission of liability (FAL) based upon Dr. Gray’s DIME
    report. However, employer did not admit to Dr. Gray’s converted
    6% whole person impairment rating or to his recommendation that
    claimant receive post-MMI ongoing maintenance medical care.
    Instead, employer admitted to the scheduled 14% permanent
    impairment of claimant’s left leg. Claimant objected to the FAL,
    arguing that he was entitled to both maintenance medical care and
    PPD benefits calculated under Dr. Gray’s recommended 6% whole
    person impairment rating.
    2
    ¶5    In November 2017, the ALJ held a hearing on the issue of
    future maintenance medical benefits. Although claimant raised the
    issue of whole person impairment benefits, the ALJ noted that,
    because claimant had not given employer sufficient notice of his
    intent to pursue that issue, employer “elected to reserve that issue
    for future determination.”
    ¶6    In a supplemental order issued in March 2018, which
    superseded a previous order the ALJ had issued, the ALJ concluded
    that employer was not bound by the DIME physician’s
    recommendation for future maintenance medical benefits and
    denied claimant’s request for ongoing care. The ALJ rejected
    claimant’s contention that a DIME physician’s opinions concerning
    future maintenance medical treatment are part of the “findings or
    determinations” referenced in section 8-42-107.2(4)(c). Rather, the
    ALJ held that “the preclusive effect [of a DIME physician’s opinion]
    is limited to determinations regarding MMI or whole person medical
    impairment.” The Panel affirmed the ALJ’s supplemental order in
    early July 2018, but claimant did not seek review of that order in
    this court.
    3
    ¶7    Less than a week after the Panel issued its order, claimant
    filed a new application for hearing, endorsing the issues of
    disfigurement and PPD benefits. Specifically, claimant indicated
    that he sought a “whole person rating from the DIME doctor J.
    Stephen Gray, M.D.” In a motion for partial summary judgment,
    claimant argued that employer was bound by Dr. Gray’s whole
    person impairment rating because it had not filed an application for
    hearing objecting to the whole person rating and had instead filed a
    FAL admitting to the 14% scheduled impairment.
    ¶8    In a written order denying claimant’s motion, the ALJ ruled
    that because the conversion of a scheduled impairment to a whole
    person impairment rating is not one of the two areas in which a
    DIME opinion carries presumptive weight, employer did not have to
    apply for a hearing to challenge the conversion. In particular, the
    ALJ ruled that because conversion from a scheduled impairment to
    a whole person impairment is not within the scope of a DIME’s
    “findings or determinations” under section 8-42-107.2(4)(c),
    employer was not required to apply for a hearing to challenge any
    impairment rating conversion. Rather, the ALJ wrote, it was
    claimant’s
    4
    burden to prove, by a preponderance of the
    evidence, that he suffered permanent
    functional impairment not listed on the
    schedule of disabilities. The DIME’s opinion
    on that point is not binding, but is simply one
    piece of evidence the ALJ will consider in
    evaluating whether [c]laimant met his burden.
    If [c]laimant proves whole person impairment,
    the DIME’s 6% whole person rating is binding
    under Leprino [Foods Co. v. Industrial Claim
    Appeals Office, 
    134 P.3d 475
    , 482 (Colo. App.
    2005)]. On the other hand, if [c]laimant fails to
    prove whole person impairment, the
    appropriate scheduled rating is a factual
    matter for determination under the
    preponderance standard.
    ¶9    The matter proceeded to hearing on three issues: (1) claimant’s
    entitlement to whole person PPD benefits; (2) claimant’s request for
    disfigurement benefits; and (3) employer’s contention that the ALJ
    was precluded from considering the PPD claim. The ALJ rejected
    employer’s issue preclusion argument but found that claimant had
    not shown by a preponderance of the evidence that his functional
    impairment extended beyond his left leg. In support of this finding,
    the ALJ credited the opinions of Dr. Hattem and a physician
    retained by employer, Dr. Mark Paz. Both physicians opined that
    claimant’s back pain was unrelated to his left ankle sprain.
    Because the ALJ found that claimant’s compensable functional
    5
    impairment was limited to the left leg, the ALJ ordered that
    claimant’s benefits be calculated according to the schedule codified
    in section 8-42-107(2). The ALJ also found that although claimant
    demonstrated a limp at the hearing, numerous physicians
    “repeatedly documented normal gait.” Based on these findings, the
    ALJ denied and dismissed claimant’s request for whole person PPD
    and disfigurement benefits.
    ¶ 10   The Panel upheld the ALJ’s decision, holding that it was
    supported by both the law and substantial evidence in the record.
    Claimant now appeals the denial of his request for whole person
    PPD benefits.
    II.    Issue Preclusion
    ¶ 11   Before examining the merits of claimant’s appeal, we address
    employer’s contention that claimant’s argument is barred by the
    doctrine of issue preclusion. Employer argues that the ALJ’s March
    2018 supplemental order denying claimant’s request for post-MMI
    maintenance medical benefits precludes claimant’s request that his
    impairment rating be converted from a scheduled impairment to an
    impairment of the whole person, as the DIME physician
    recommended. In the March 2018 supplemental order, the ALJ
    6
    ruled that employer was not bound by Dr. Gray’s recommendation
    that claimant receive ongoing post-MMI maintenance medical
    benefits because that recommendation fell outside the scope of
    “findings or determinations” addressed in section 8-42-107.2(4)(c).
    The ALJ reasoned that the “findings or determinations” covered by
    section 8-42-107.2(4)(c) are limited to those DIME opinions given
    preclusive effect by statute — i.e., whole person impairment and
    MMI. The Panel agreed, concluding that “the reference in [section]
    8-42-107.5(4)(c)1 to ‘findings or determinations’ of the DIME report
    are necessarily limited to findings or determinations of MMI or
    permanent impairment.” Claimant did not appeal this order, and
    employer now argues that he should be barred from seeking whole
    person PPD benefits under section 8-42-107.2(4)(c) by the doctrine
    of issue preclusion. We disagree.
    A.   Law Governing Issue Preclusion
    ¶ 12   An issue involving the same parties may only be decided once.
    Under the doctrine of issue preclusion, “once a court has decided
    1 The Panel’s reference to section 8-42-107.5 appears to be a
    typographical error. The rest of the Panel’s order correctly cites to
    section 8-42-107.2(4)(c), C.R.S. 2019.
    7
    an issue necessary to its judgment, the decision will preclude
    relitigation of that issue in a later action involving a party to the
    first case.” People v. Tolbert, 
    216 P.3d 1
    , 5 (Colo. App. 2007). Issue
    preclusion applies if
    (1) the issue sought to be precluded is identical
    to an issue actually determined in the prior
    proceeding; (2) the party against whom
    estoppel is asserted has been a party to or is in
    privity with a party to the prior proceeding; (3)
    there is a final judgment on the merits in the
    prior proceeding; and (4) the party against
    whom the doctrine is asserted had a full and
    fair opportunity to litigate the issue in the
    prior proceeding.
    Sunny Acres Villa, Inc. v. Cooper, 
    25 P.3d 44
    , 47 (Colo. 2001).
    “Issue preclusion applies to administrative proceedings, including
    those involving workers’ compensation claims.” Youngs v. Indus.
    Claim Appeals Office, 2012 COA 85M, ¶ 52.
    ¶ 13   The party seeking to preclude an issue from relitigation bears
    the burden of establishing the elements of the doctrine. See Allen v.
    Martin, 
    203 P.3d 546
    , 560 (Colo. App. 2008).
    ¶ 14   “Issue preclusion . . . presents a question of law that we review
    de novo.” Bristol Bay Prods., LLC v. Lampack, 
    2013 CO 60
    , ¶ 17.
    8
    B.    The Issue Is Not Precluded
    ¶ 15   As employer concedes, “claimant’s argument here deviates
    slightly from the argument he asserted previously.” At the
    November 2017 hearing, claimant argued that employer was bound
    by the DIME physician’s recommendation for post-MMI
    maintenance medical benefits. In contrast, in his motion for partial
    summary judgment filed in advance of the November 2018 hearing,
    claimant maintained that employer was bound by the DIME
    physician’s whole person impairment rating. The issues are
    similar, as both rely on the ALJ’s interpretation of the scope of
    “findings or determinations” under section 8-42-107.2(4)(c), but
    they are not identical. The question raised at the November 2017
    hearing was whether “findings or determinations” included
    post-MMI maintenance medical treatment. If so, then employer
    could have been bound by Dr. Gray’s recommendation that
    claimant receive ongoing post-MMI maintenance medical benefits.
    ¶ 16   In contrast, in his motion for partial summary judgment, as on
    appeal, claimant argued that employer was bound by Dr. Gray’s
    conversion of scheduled impairment to a nonscheduled whole
    person impairment because the conversion recommendation fell
    9
    within the section 8-42-107.2(4)(c)’s definition of “findings or
    determinations.” However, “findings or determinations” could have
    incorporated one of Dr. Gray’s recommendations but not the other;
    the questions necessitated separate discussion and analysis to
    determine whether either maintenance medical benefits or
    conversion fell within the purview of “findings or determinations.”
    The issues therefore are not identical for issue preclusion purposes.
    Employer consequently cannot establish the first prong of the issue
    preclusion test. See Sunny Acres Villa, 25 P.3d at 47.
    ¶ 17      Moreover, although claimant tried to assert his claim for PPD
    benefits based on Dr. Gray’s conversion of his scheduled
    impairment into a whole person impairment at the November 2017
    hearing, the parties and the ALJ agreed to reserve the question for
    future consideration. We agree with the ALJ that, under these
    circumstances, the question is not precluded.
    III.   DIME’s Scheduled Impairment Recommendation Not Binding
    ¶ 18      Having determined that claimant’s primary contention is not
    precluded, we now turn to the merits of his appeal. As he argued
    before both the ALJ and the Panel, claimant contends employer is
    bound by the DIME physician’s whole person impairment rating
    10
    because employer did not apply for a hearing contesting it. He
    argues that an employer must respond to “any finding or
    determination of [a] DIME doctor” within twenty days or the finding
    or determination becomes binding. He further argues that the ALJ
    and the Panel misinterpreted section 8-42-107.2(4)(c) when they
    excluded conversion to a whole person impairment rating from
    “findings or determinations.” We are not persuaded that either the
    ALJ or the Panel erred.
    A.   Law Governing Statutory Interpretation
    ¶ 19   It is the court’s function to decide issues of law, including the
    interpretation of statutes. § 24-4-106(7)(d), C.R.S. 2019 (“In all
    cases under review, the court shall determine all questions of law
    and interpret the statutory and constitutional provisions involved.”).
    When we interpret a provision of the Act, if its language is clear “we
    interpret the statute according to its plain and ordinary meaning.”
    Davison v. Indus. Claim Appeals Office, 
    84 P.3d 1023
    , 1029 (Colo.
    2004). In addition, “when examining a statute’s language, we give
    effect to every word and render none superfluous because we ‘do
    not presume that the legislature used language idly and with no
    intent that meaning should be given to its language.’” Lombard v.
    11
    Colo. Outdoor Educ. Ctr., Inc., 
    187 P.3d 565
    , 571 (Colo. 2008)
    (quoting Colo. Water Conservation Bd. v. Upper Gunnison River
    Water Conservancy Dist., 
    109 P.3d 585
    , 597 (Colo. 2005)).
    B.    Panel and ALJ Did Not Misinterpret Statute
    ¶ 20   Section 8-42-107.2(4)(c) provides as follows:
    Within twenty days after the date of the
    mailing of the division’s notice that it has
    received the [D]IME’s report, the insurer or
    self-insured employer shall either file its
    admission of liability pursuant to section 8-43-
    203[, C.R.S. 2019,] or request a hearing before
    the division contesting one or more of the
    [D]IME’s findings or determinations contained
    in such report.
    Claimant insists that the “findings or determinations” referenced in
    this subsection encompass any findings included in a DIME report.
    ¶ 21   The Panel concluded that the term “findings or
    determinations” is limited to a DIME physician’s findings
    concerning MMI and whole person permanent impairment.
    Consequently, the Panel ruled that employer was not bound by the
    DIME physician’s conversion of the 14% scheduled lower extremity
    impairment to a 6% whole person impairment and could either file
    a final admission or apply for a hearing.
    12
    ¶ 22   We conclude that the Panel’s interpretation is consistent with
    the statutory language and legislative intent. First, when we
    consider the Workers’ Compensation Act of Colorado (Act) as a
    whole, it becomes clear that the legislature did not intend for a
    DIME physician’s “findings or determinations” to be unlimited in
    scope. In particular, cross-references between section 8-42-107.2,
    which governs DIMEs, and section 8-42-107, which governs PPD
    benefits, illuminate the meaning and scope of “findings or
    determinations.” Addressing MMI, section 8-42-107(8)(b)(II)
    provides that “[i]f either party disputes a determination by an
    authorized treating physician on the question of whether the
    injured worker has or has not reached [MMI], an independent
    medical examiner may be selected in accordance with section
    8-42-107.2.” (Emphasis added.) Likewise, in the subsection
    pertaining to permanent impairment, the statute instructs that
    when
    there is a determination that permanent
    medical impairment has resulted from the
    injury, the authorized treating physician shall
    determine a medical impairment rating as a
    percentage of the whole person. . . . If either
    party disputes the authorized treating
    physician’s finding of medical impairment, . . .
    13
    the parties may select an independent medical
    examiner in accordance with section 8-42-
    107.2.
    § 8-42-107(8)(c) (emphasis added). These are the only two
    “determinations” that the Act expressly permits a DIME physician
    to evaluate, and the only two references to DIME “determinations”
    in these two statutory sections. Conversion of a scheduled
    impairment to a whole person impairment is not so
    cross-referenced in the statutes.
    ¶ 23   Second, close analysis confirms that the two areas referred to
    in these statutes as “determinations” are those in which the Act
    grants a DIME presumptive effect. As has long been the case, a
    DIME physician’s opinions concerning MMI and impairment of the
    whole person are binding unless overcome by clear and convincing
    evidence. § 8-42-107(8)(b)(III); Meza v. Indus. Claim Appeals Office,
    
    2013 COA 71
    , ¶ 15. The Act has not granted DIME opinions
    presumptive weight in any other areas. Instead, the “opinions of a
    DIME physician have only been given presumptive effect when
    expressly required by the statute.” Cordova v. Indus. Claim Appeals
    Office, 
    55 P.3d 186
    , 190 (Colo. App. 2002).
    14
    ¶ 24   The Act “classifies work-related injuries as either scheduled or
    non-scheduled injuries. Scheduled injuries are those listed in
    [section] 8-42-107(2). Non-scheduled injuries are those that are not
    listed or that are excluded from the statutory schedule.” Delaney v.
    Indus. Claim Appeals Office, 
    30 P.3d 691
    , 693 (Colo. App. 2000).
    [A] claimant is limited to a scheduled disability
    award if he or she suffers an injury or injuries
    described in the schedule set forth in [section]
    8-42-107(2). . . . Where a claimant suffers an
    injury not enumerated in [section] 8-42-107(2),
    the claimant is entitled to whole person
    impairment benefits under [section] 8-42-
    107(8).
    Dillard, 121 P.3d at 304. Nowhere in the Act is a DIME’s
    recommendation to convert a scheduled impairment to a whole
    person impairment expressly granted any presumptive effect.
    ¶ 25   Rather, divisions of this court have long entrusted the
    conversion of a scheduled injury to a whole person impairment to
    the ALJ’s discretionary authority. See Strauch v. PSL Swedish
    Healthcare Sys., 
    917 P.2d 366
    , 368 (Colo. App. 1996). Whether to
    convert a scheduled impairment to an impairment of the whole
    person is, thus, a question of fact for the ALJ to decide. 
    Id.
     And
    even though this has long been the stated standard, the legislature
    15
    has never added impairment conversions to the short list of
    conclusions over which a DIME’s opinion carries presumptive
    weight, despite enacting section 8-42-107.2 two years after Strauch
    and amending the statute at least six times since. The legislature’s
    inaction amounts to tacit approval of the case law imbuing ALJs
    with the discretionary authority to decide whether an impairment
    rating should be converted. See City of Colorado Springs v. Powell,
    
    156 P.3d 461
    , 467 (Colo. 2007) (“We regard the General Assembly’s
    decision not to alter the definition of ‘sanitation facility’ following
    these cases — even though it made several other amendments . . .
    after these decisions — as evidence of its acquiescence to the
    judicial construction of the terms in those opinions.”); Tompkins v.
    DeLeon, 
    197 Colo. 569
    , 571, 
    595 P.2d 242
    , 243-44 (1979) (“When
    the legislature reenacts or amends a statute and does not change a
    section previously interpreted by settled judicial construction, it is
    presumed that it agrees with judicial construction of the statute.”).
    ¶ 26   Nor are we persuaded by claimant’s assertion that City Market,
    Inc. v. Indus. Claim Appeals Office, 
    68 P.3d 601
     (Colo. App. 2003),
    counsels a different result. Even if, as claimant notes, there is a
    dearth of cases addressing the question he raises, City Market does
    16
    not assist us in our analysis. It is inapposite and factually
    distinguishable because there, unlike here, the employer took no
    steps to contest the DIME. Having filed neither an application for
    hearing nor a FAL, the employer in City Market was bound by the
    “findings or determinations” identified in the DIME opinion. 
    Id. at 603
     (“When employer received the DIME report, it was required
    under the Act and the rule to respond and either admit that the
    DIME report was valid or request a hearing at which it could raise
    its objections to the report.”). Employer here admitted to the
    scheduled impairment recommended by the DIME; it was not
    required to do more because claimant bore the burden of proving he
    had sustained an injury to his whole person. See Walker v. Jim
    Fuoco Motor Co., 
    942 P.2d 1390
    , 1392 (Colo. App. 1997).
    ¶ 27   We agree with the Panel that a DIME’s “findings or
    determinations” under section 8-42-107.2(4)(c) do not include
    conversion of a scheduled impairment to a nonscheduled
    impairment of the whole person. Accordingly, employer was not
    bound by Dr. Gray’s suggestion that claimant’s impairment rating
    be converted from 14% of the lower extremity to 6% of the whole
    person even though it filed a FAL admitting to the scheduled
    17
    impairment and did not also file an application for a hearing
    contesting the conversion recommendation.
    C.      The Panel Properly Upheld the ALJ’s Finding that Claimant’s
    Injury Fell Under the Schedule of Injuries
    ¶ 28    To the extent that claimant suggests that the Panel erred by
    affirming the ALJ’s finding that his injury was limited to his lower
    extremity, we perceive no grounds for setting aside the order on this
    basis.
    ¶ 29    The Act draws a clear distinction between scheduled and
    nonscheduled — i.e., whole person — impairment. Injuries either
    fall within the schedule codified at section 8-42-107(2) and are
    described as scheduled injuries, or they fall outside the scope of the
    schedule or are excluded and are considered nonscheduled or
    whole person injuries. See Delaney, 
    30 P.3d at 693
    ; Dillard, 121
    P.3d at 304.
    ¶ 30    When a claimant has sustained a nonscheduled, whole person
    impairment, the DIME physician’s rating of that impairment is
    granted presumptive weight. See Meza, ¶ 15. However, such
    presumptive weight is not granted a DIME physician’s opinion with
    respect to scheduled injuries. See Delaney, 
    30 P.3d at
    693
    18
    (recognizing that the requirement that “a DIME finding as to
    permanent impairment . . . be overcome . . . by clear and convincing
    evidence . . . appl[ies] only to non-scheduled impairments”). “When
    there is a dispute concerning causation or relatedness in a case
    involving only a scheduled impairment, the ALJ will continue to
    have jurisdiction to resolve that dispute.” Egan v. Indus. Claim
    Appeals Office, 
    971 P.2d 664
    , 666 (Colo. App. 1998).
    ¶ 31   “[W]hether the claimant has suffered a functional impairment
    that is listed on the schedule of disabilities is a factual question to
    be resolved by the ALJ.” Strauch, 
    917 P.2d at 368
    . In other words,
    whether to categorize an injury as limited to one body part
    enumerated on the schedule set out in section 8-42-107(2) or to
    rate it as an impairment of the whole person is a question of fact for
    the ALJ. If an ALJ determines that an injury warrants a whole
    person rating and should not be limited to the statutory schedule,
    any whole person rating calculated by the DIME physician would be
    granted presumptive weight. As explained in Strauch,
    the determination whether the claimant has
    suffered a functional impairment that is listed
    on the schedule of disabilities is a factual
    question to be resolved by the ALJ. This
    determination is distinct from, and should not
    19
    be confused with, the treating physician’s
    rating of physical impairment under the AMA
    Guides.
    
    Id.
     (citation omitted). The claimant bears the burden of establishing
    entitlement to a nonscheduled, whole person impairment rating.
    See Walker, 
    942 P.2d at 1392
     (upholding ALJ’s finding that the
    claimant failed to prove entitlement to PPD benefits calculated
    based on a whole person impairment rating because finding was
    supported by substantial evidence).
    ¶ 32   “[T]he situs of the functional impairment, not the situs of the
    initial harm” determines whether claimant’s injury falls under the
    schedule or should be calculated based upon an impairment of the
    whole person. Strauch, 
    917 P.2d at 369
    . Thus, the ALJ had the
    sole discretion to decide whether claimant met his burden of
    demonstrating that his injury extended beyond his leg to his back
    and should be calculated at the 6% whole person impairment rating
    as converted by the DIME physician, Dr. Gray. The ALJ found,
    though, that claimant had not met his burden and that his injury
    was limited to his left leg. Because that determination was factual
    and fell squarely within the ALJ’s purview, the Panel had to uphold
    it if it was supported by substantial evidence in the record. See
    20
    Langton v. Rocky Mountain Health Care Corp., 
    937 P.2d 883
    , 884
    (Colo. App. 1996) (holding that the question whether a claimant’s
    impairment falls within the schedule of benefits is one of fact for the
    ALJ). And, as set out in his order, the ALJ’s finding was supported
    by the opinions of both Dr. Hattem and Dr. Paz.
    ¶ 33   Because substantial evidence supports the ALJ’s finding that
    claimant’s work-related injury was limited to his left lower extremity
    and did not extend to his back, the Panel properly upheld the ALJ’s
    determination that claimant sustained a scheduled impairment
    under section 8-42-107(2).
