    FOR THE DISTRICT OF COLUMBIA
    ANTONIO W.,1
    Plaintiff,
    v.                                                         Civil Action No.
    20-cv-1920
    KILOLO KIJAKAZI, Acting
    Commissioner of Social Security,2
    Defendant.
    MEMORANDUM OPINION
    Plaintiff Antonio W. seeks review of the final decision of the Acting Commissioner of
    Social Security, Dr. Kilolo Kijakazi (“Defendant” or “the Commissioner”), denying his claim for
    Supplemental Security Income Benefits (“SSI”). ECF No. 12–1 at 1. Plaintiff alleges that
    Defendant’s decision, which adopted the findings of an Administrative Law Judge (“ALJ”), is not
    supported by substantial evidence and is erroneous as a matter of law. Id. Plaintiff seeks either
    judgment as a matter of law in his favor or remand to the Social Security Administration (“SSA”)
    for a new hearing. Id. Defendant moves for affirmance of the ALJ’s decision. ECF No. 14 at 1–
    2.3

    The relevant docket entries for purposes of this Opinion are: (1) the Administrative Record
    (ECF No. 8 and its attachments); (2) Plaintiff’s Motion for Judgment of Reversal (ECF No. 12);
    Having reviewed the Administrative Record,4 the Parties’ briefs, and the relevant law, this
    Court will GRANT IN PART and DENY IN PART the Parties’ motions (ECF Nos. 12–1 and
    14) and remand this case to the Social Security Administration for further proceedings consistent
    with this opinion.
    BACKGROUND
    A. THE SOCIAL SECURITY ACT
    To qualify for benefits under the Social Security Act (“the Act”), the Commissioner must
    find that the claimant has a “disability.” See 
    42 U.S.C. §§ 423
    (a)(1)(E), 1382(a)(1). The Act
    defines “disability” as the “inability to engage in any substantial gainful activity by reason of any
    medically determinable physical or mental impairment which . . . has lasted or can be expected to
    last for a continuous period of not less than 12 months.”             
    42 U.S.C. §§ 423
    (d)(1)(A),
    1382c(a)(3)(A).
    The Commissioner uses a five-step process to determine whether a claimant is disabled.
    
    20 C.F.R. § 416.920
    (a)(4). At the first step, the claimant must prove that he is not engaged in
    “substantial gainful activity.” 
    20 C.F.R. §§ 404.1520
    (a)(4), 416.920(a)(4). At step two, the
    claimant must show that he has a “severe medically determinable physical or mental impairment,”
    or combination of impairments, which lasts for at least twelve consecutive months. 
    20 C.F.R. §§ 404.1509
    , 404.1520(a)(4), 416.920(a)(4). The third step requires the claimant to prove that his
    impairment is equivalent to one of the impairments listed in the appendix of the relevant disability
    (3) Defendant’s Motion for Judgment of Affirmance and in Opposition to Plaintiff’s Motion for
    Judgment of Reversal (ECF No. 14); and (4) Plaintiff’s Reply to Defendant’s Memorandum in
    Support for Judgment of Affirmance (ECF No. 18). When referring to page numbers in the record,
    the Court uses the numbers assigned by the Court’s CM/ECF system.

    Citations to the Administrative Record, ECF No. 8, are referred to as “AR.” The Court
    will cite to the consecutive page numbers provided in the lower right-hand corner of each page of
    the AR.
    2
    regulation. See 
    20 C.F.R. §§ 404.1520
    (a)(4), 416.920(a)(4); see also 20 C.F.R. Pt. 404, Subpt. P,
    App. 1 (1989) (“the Listings”) (describing for each of the major body systems impairments
    considered severe enough to prevent an individual from doing gainful activity, regardless of age,
    education, or work experience).
    If the claimant successfully satisfies the first three steps, the Commissioner will find that
    the claimant is disabled. 
    20 C.F.R. §§ 404.1520
    (a)(4), 416.920(a)(4). If not, the inquiry proceeds
    to steps four and five following an assessment of the claimant’s residual functional capacity
    (“RFC”). See Hall v. Kijakazi, No. 20-cv-2073, 
    2022 WL 343505
    , at *2 (D.D.C. Feb. 4, 2022)
    (citing 
    20 C.F.R. § 416.920
    (e)). The RFC is “what an individual can still do despite his or her
    limitations.” SSR 96–8p, 
    1996 WL 374184
    , at *2. It requires an assessment “of the extent to
    which an individual’s medically determinable impairment(s), including any related symptoms . . .
    may cause physical or mental limitations or restrictions that may affect his or her capacity to do
    work-related physical and mental activities.” 
    Id.
     The RFC reflects an individual’s “maximum
    remaining ability to do sustained work activities.” 
    Id.
     (emphasis added).
    At step four, the claimant must compare the RFC assessment with the physical and mental
    demands of his past relevant work and demonstrate that his impairments prevent him from
    performing that work. See 
    20 C.F.R. §§ 404.1520
    (a)(4), 416.920(a)(4). At step five, the burden
    shifts to the Commissioner to identify specific jobs available in the national economy that the
    claimant can perform in light of his age, education, work experience, and RFC. See id.; see also
    Callahan v. Astrue, 
    786 F. Supp. 2d 87
    , 89 (D.D.C. 2011). In making this determination, the ALJ
    may call upon a vocational expert to testify at the administrative hearing as to whether, based on
    the claimant’s RFC, he can perform other work that exists in the national economy. Callahan, 
    786 F. Supp. 2d at 90
    . When testifying, the vocational expert may rely on sources such as the
    3
    Dictionary of Occupation Titles (“DOT”), which is a compilation of “‘standardized occupational
    information’ that provides a brief description of occupations within the national economy and lists
    the capabilities that each occupation requires of a worker.” 
    Id.
     (citing DOT, 
    1991 WL 645964
    (1991)).
    B. PLAINTIFF’S DISABILITY CLAIMS AND PROCEDURAL HISTORY
    Plaintiff was born on February 24, 2001. AR at 233. At the time of the August 20, 2019,
    administrative hearing, Plaintiff was in the twelfth grade. AR at 54. Plaintiff lives with his mother
    in an apartment in Washington, D.C. ECF No. 12–1 at 2. Plaintiff was born prematurely and
    alleges that his disability began at birth. 
    Id.
     at 1–2. His claims are based on physical impairments
    (including cerebral palsy, usage of leg braces, allergies, and asthma) as well as mental impairments
    (including mild recurrent major depression and attention deficit hyperactivity disorder
    (“ADHD”)). AR at 40, 122. Although Plaintiff used to wear leg braces all day, as of the
    administrative hearing, he used them only while sleeping. AR at 462. Plaintiff also has a history
    of ADHD which has caused problems with attention and concentration. AR at 40. Plaintiff
    testified that he takes medication to manage his ADHD and allergies. AR at 38.
    Plaintiff previously filed for SSI on June 28, 2013. AR at 25. The Commissioner denied
    Plaintiff’s first application for SSI on August 9, 2013, and upon reconsideration on November 14,
    2013. AR at 25. Plaintiff filed a second application for SSI benefits on August 29, 2017, which
    the Commissioner denied on October 24, 2017, and upon reconsideration on February 16, 2018.
    AR at 25, 149–51, 158–61. Plaintiff filed a written request for an administrative hearing on July
    7, 2018, which the ALJ held on August 20, 2019. AR at 25.
    4
    C. THE ADMINISTRATIVE HEARING
    At the hearing, the ALJ heard testimony from three witnesses: Plaintiff, his mother, and a
    vocational expert. AR at 50. When the ALJ questioned Plaintiff, he testified that he was eighteen
    years old and lived in an apartment with his mother. AR at 53–54. He explained that he was
    currently in the twelfth grade after being held back for one year because of his excessive absences.
    AR at 54. Plaintiff testified that he did not like attending school because his peers teased him for
    the way that he walks. AR at 55. Plaintiff also described his work history and shared that he has
    not completed any paid work since August 2017. AR at 65–66.
    In addition, Plaintiff testified about his mental health. Plaintiff explained that he is capable
    of bathing and dressing himself without reminders. AR at 66–67. Plaintiff confirmed that he has
    an Individualized Educational Plan (“IEP”) at school. AR at 58. Plaintiff testified that he has
    taken medication under his mother’s supervision for suicidal ideations and ADHD. AR at 58–60.
    Plaintiff described that the medication to treat his suicidal ideations made him feel dizzy and light-
    headed, and as such, he stopped taking that medication approximately three months before the
    hearing. AR at 58. Plaintiff testified that he takes the ADHD medication only during the school
    year. AR at 60. Specifically, Plaintiff revealed that in the past, he experimented with self-
    mutilation and suicide, including attempting suicide at least two times by ingesting a large amount
    of medication. AR at 70–74. Despite his struggles with suicidal ideation and self-mutilation,
    Plaintiff testified that he no longer acts on those impulses due to his desire to live and care for his
    nieces and nephews. AR at 71.
    Plaintiff also elaborated on his physical limitations. He explained that he spent the past
    summer stretching his legs to improve his walking before the new school year. AR at 56. Plaintiff
    5
    testified that he occasionally spends time playing pick-up basketball with his friends, but he cannot
    play for longer than an hour before experiencing pain in his legs. AR at 60–62.
    Vocational expert Robert Edwards was the second witness to testify during the hearing.
    AR at 78. The ALJ asked Edwards a hypothetical question about an individual of the same age
    and education as Plaintiff. AR at 78–79. The ALJ instructed Edwards to assume that the
    hypothetical person could perform only medium work and limited the individual’s job prospects
    to “simple, routine, repetitive tasks,” and “[n]o production rate or pace of work.” AR at 78–79.
    Furthermore, the ALJ asked Edwards to assume that the hypothetical individual could frequently
    climb ramps and stairs and stoop, occasionally climb ropes, ladders, and scaffolds, occasionally
    interact with the general public and coworkers, and occasionally tolerate changes in the work
    setting. AR at 78–79. Assuming those parameters, Edwards testified that the hypothetical
    individual could perform medium unskilled jobs, such as a sandwich maker, a grocery bagger, and
    a night stocker. AR at 79.
    The ALJ then modified his hypothetical question in two ways to limit the capacity of the
    hypothetical individual. AR at 79. First, the ALJ asked Edwards if jobs in the national economy
    would exist if the hypothetical person could only occasionally interact with supervisors. AR at 79
    (emphasis added). Second, the ALJ asked if jobs in the national economy would exist if the
    hypothetical person could only occasionally climb ramps and stairs, and stoop, and never climb
    ramps, ladders, or scaffolds.     AR at 79 (emphasis added).         Edwards responded that the
    modifications would make no difference in the number of jobs available for the hypothetical
    person. AR at 79.
    Plaintiff’s mother Stacey W. testified as the final witness. AR at 84. Stacey W. first
    discussed Plaintiff’s medications. AR at 84. She explained that Plaintiff takes medication for
    6
    sleeping, ADHD, and depression with suicidal ideation. AR at 84. While being questioned by
    Plaintiff’s attorney, Stacey W. explained that Plaintiff wore braces on his legs until he was fifteen
    years old. AR at 89. After that point, Plaintiff only wore leg braces overnight. AR at 89. Stacey
    W. explained that Plaintiff cannot walk for long periods and is unable to walk up the stairs. AR at
    89. Stacey W. testified that Plaintiff had three surgeries on each of his legs—two to each of his
    right and left Achilles’ tendons and one to the backside of his right and left knees. AR at 90–91.
    Stacey W. explained that when Plaintiff complains about pain in his legs, she has to massage his
    legs to ease the tension in his muscles. AR at 90.
    Stacey W. concluded her testimony by discussing Plaintiff’s mental health and interactions
    with others. AR at 93–97. Stacey W. shared more details about Plaintiff’s suicidal ideations and
    suicide attempts. AR at 93. She explained that Plaintiff attempted to overdose on Benadryl, but
    Stacey W. made him spit out the pills. AR at 96. Plaintiff verbally threatened to use a firearm,
    but Stacey W. never physically saw Plaintiff with a weapon. AR at 96. Finally, although Plaintiff
    was conscious of the attention his manner of walking received when out in public, Plaintiff was
    generally able to make friends outside of his family. AR at 97.
    D. THE ALJ’S DECISION
    The ALJ issued his decision on September 24, 2019, finding that Plaintiff was not disabled
    under the Act. AR at 26. At step one, the ALJ found that Plaintiff had not engaged in substantial
    gainful activity since the application date, August 29, 2017. AR at 29. At step two, the ALJ found
    that Plaintiff had the following severe impairments: (1) cerebral palsy; (2) ADHD; (3) affective
    mood disorder; and (4) learning disorder. AR at 29.
    At step three, the ALJ found that Plaintiff does not have an impairment or combination of
    impairments that meets or is the medical equivalent of one of the Listings. AR at 29–30.
    7
    Specifically, the ALJ considered listings 11.00, 12.05, and 112.05. AR at 29–32. Under Listing
    11.00 (Neurological Disorders), the ALJ found that Plaintiff’s joints were generally stable even
    though his range of motion was impaired. AR at 29. The ALJ also found that Plaintiff did not
    require help getting up from a seated position or have any deficiencies with his bilateral grip
    strength. AR at 29–30. Furthermore, the ALJ noted that Plaintiff testified that he plays basketball
    with his friends and can run and jump. AR at 30.
    Under Listing 12.05 (Intellectual Disorder), the ALJ found that Plaintiff’s impairments did
    not satisfy the “Paragraph A” criteria because Plaintiff was not dependent on others for basic needs
    such as bathing, dressing, or eating.5 AR at 30. The ALJ found that Plaintiff did not satisfy the
    “Paragraph B” criteria because Plaintiff had only moderate or mild limitations in the three areas
    of mental functioning evaluated.6 AR at 31. The ALJ found that Plaintiff did not satisfy the
    “Paragraph C” criteria because Plaintiff “has more than minimal capacity to adapt to changes in
    his environment or to demands that are not already part of his daily life.” AR at 32.
    Under Listing 112.05 (Intellectual Disorder), the ALJ found that Plaintiff had, at most, less
    than marked limitation in each of the six functional equivalence domains. AR at 32. The ALJ
    found that Plaintiff had no limitation in acquiring and using information and caring for himself.
    AR at 32–36. Additionally, the ALJ found that Plaintiff had less than marked limitation in
    attending and completing tasks, interacting and relating with others, moving about and
    manipulating objects, and health and physical wellbeing. AR at 32–36.
    5
    To satisfy the Paragraph A criteria under Listing 12.05, a claimant must show
    “[s]ignificantly subaverage general intellectual functioning . . . significant deficits in current
    adaptive functioning . . . and [] evidence [that] the disorder began prior to [claimant’s] attainment
    of age 22.”
    6
    Paragraph B requires (1) significantly subaverage general intellectual functioning, (2)
    significant deficits in adaptive functioning, (3) evidence that these intellectual and adaptive
    impairments support the conclusion that the disorder began prior to attainment of age twenty–two.
    8
    At step four, the ALJ determined that Plaintiff had the RFC to perform medium work with
    the following limitations:
    [Plaintiff] can frequently climb ramps and stairs, occasionally climb
    ropes, ladders, and scaffolds, and frequently stoop. He must avoid
    concentrated exposure to fumes, odors, dusts, and gases. [Plaintiff]
    is limited to jobs involving simple, routine, repetitive tasks,
    occasional changes in the work setting, occasional judgment or
    decisionmaking, and where there would be no production rate for
    pace of work. He can occasionally interact with the general public
    and co-workers.
    AR at 37–38. At step five, considering Plaintiff’s age, education, work experience, and RFC, the
    ALJ determined that there were a significant number of jobs in the national economy that Plaintiff
    can perform. AR at 42.
    When assessing Plaintiff’s RFC in conjunction with steps four and five, the ALJ considered
    the hearing testimony, prior administrative medical findings, and the medical evidence and
    opinions of record. AR at 37. In concluding that Plaintiff was not disabled, the ALJ evaluated
    “all symptoms and the extent to which these symptoms can reasonably be accepted as consistent
    with the objective medical evidence and other evidence.” AR at 37. The ALJ also reviewed
    opinion evidence on Plaintiff’s physical and mental impairments from the following: Drs. Gregor
    Price and Elizabeth Nolte, Licensed Independent Clinical Social Worker Eva Ogbuokiri, and
    Licensed Independent Social Worker Daryl Lowe. AR at 39–40.
    The ALJ’s decision became final when the Appeals Council denied Plaintiff’s request for
    review on May 12, 2020. AR at 1.
    LEGAL STANDARD
    A federal district court has jurisdiction over a challenge to the final decision of the
    Commissioner. 
    42 U.S.C. § 405
    (g). A reviewing court must affirm the Commissioner’s decision
    if it is based on substantial evidence in the record and the correct application of the relevant legal
    9
    standards. Id.; Butler v. Barnhart, 
    353 F.3d 992
    , 999 (D.C. Cir. 2004); Smith v. Bowen, 
    826 F.2d 1120
    , 1121 (D.C. Cir. 1987).
    Substantial evidence is “such relevant evidence as a reasonable mind might accept as
    adequate to support a conclusion.” Butler, 
    353 F.3d at 999
     (quoting Richardson v. Perales, 
    402 U.S. 389
    , 401 (1971)). This standard “‘requires more than a scintilla, but can be satisfied by
    something less than a preponderance of the evidence.’” Fla. Mun. Power Agency v. FERC, 
    315 F.3d 362
    , 365–66 (D.C. Cir. 2003) (quoting FPL Energy Me. Hydro LLC v. FERC, 
    287 F.3d 1151
    ,
    1160 (D.C. Cir. 2002)). Ultimately, substantial evidence is a “low bar,” Louisiana Pub. Serv.
    Comm’n v. FERC, 
    20 F.4th 1
    , 7 (D.C. Cir. 2021), and “requires considerable deference to the
    decision rendered by the ALJ.” Crosson v. Shalala, 
    907 F. Supp. 1
    , 3 (D.D.C. 1995).
    On review, the Court may not reweigh the evidence. Butler, 
    353 F.3d at 999
    . Instead, it
    is the Court’s role to “carefully scrutinize the entire record to ensure that the Commissioner,
    through the ALJ, has both analyzed all of the evidence available and has sufficiently explained
    his/her reasoning and the weights given to the facts.” Pinkney v. Astrue, 
    675 F. Supp. 2d 9
    , 14
    (D.D.C. 2009). In performing this role, the Court must “. . . be mindful of the harmless-error rule.
    Consequently, even if [the Court] perceive[s] error,” it must “affirm the Commission’s decision
    unless the error is prejudicial.” Saunders v. Kijakazi, 
    6 F.4th 1
    , 5 (D.C. Cir. 2021) (internal citation
    omitted).
    “‘[P]laintiff bears the burden of demonstrating that the Commissioner’s decision [is] not
    based on substantial evidence or that incorrect legal standards were applied.’” Settles v. Colvin,
    
    121 F. Supp. 3d 163
    , 169 (D.D.C. 2015) (quoting Muldrow v. Astrue, No. 11–1385, 
    2012 WL 2877697
    , at *6 (D.D.C. July 11, 2012)). If the plaintiff meets this burden and the Court finds the
    ALJ erred, the Court may reverse and remand, requiring the ALJ to conduct further proceedings
    10
    consistent with the law. See, e.g., Jackson v. Barnhart, 271 F. Supp. 2d. 30, 38 (D.D.C. 2002).
    Conversely, if the Court finds that the ALJ based his decision on substantial evidence and applied
    the correct legal standards, the Court may grant the Commissioner’s motion for affirmance. See,
    e.g., Hicks v. Astrue, 
    718 F. Supp. 2d 1
    , 17 (D.D.C. 2010).
    DISCUSSION
    Plaintiff advances three arguments in support of his claim that the ALJ erroneously
    assessed his RFC. First, Plaintiff claims that the ALJ failed to adequately explain the evidence
    upon which he relied to make his determination and specifically failed to explain the term
    “production rate for pace of work.” ECF No. 12–1 at 6. Second, Plaintiff asserts that the ALJ
    failed to include limitations on concentration, persistence, or pace in both the RFC assessment and
    the hypothetical question posed to the vocational expert. 
    Id. at 9
    . Finally, Plaintiff argues that the
    ALJ failed to perform a proper function-by-function assessment of Plaintiff’s abilities to perform
    work-related activities. 
    Id. at 13
    .
    A. THE ALJ ADEQUATELY EXPLAINED THE EVIDENCE UPON WHICH HE RELIED
    Plaintiff takes issue with the ALJ’s conclusion that Plaintiff could perform “simple,
    routine, repetitive tasks, with no production rate for pace of work.” 
    Id. at 6
     (emphasis added); AR
    at 37. Plaintiff claims that the phrase “production rate for pace of work” does not contain sufficient
    information for this Court to determine whether the ALJ logically applied the available evidence
    when forming Plaintiff’s RFC. ECF No. 12–1 at 9. Consequently, Plaintiff argues the ALJ’s RFC
    assessment defies review and requires reversal. 
    Id.
    Defendant argues that Plaintiff erroneously analogizes the phrase “no production rate for
    pace of work” in this case to the phrase “production rate or demand pace” found in Thomas v.
    Berryhill, 
    916 F.3d 307
    , 312–13 (4th Cir. 2019). ECF No. 14 at 18–21. Defendant claims this
    11
    analogy is erroneous for two reasons. First, the phrase used in this case is commonly used and
    self-explanatory. 
    Id. at 19
    . Second, the ALJ provided additional context within the RFC to
    logically explain how the RFC limitation addresses Plaintiff’s ability to concentrate, persist, or
    maintain pace. 
    Id. at 21
    . This Court agrees with Defendant.
    In rendering his decision, the ALJ must provide “a statement of the case, in understandable
    language, setting forth a discussion of the evidence, and stating the Commissioner’s determination
    and the reason or reasons upon which it is based.” 
    42 U.S.C. § 405
    (b)(1) (emphasis added). In
    other words, “[a]n ALJ must supply a rationale for his or her decision.” Rice v. Massanari, No.
    01–1349 (GK), 
    2002 WL 34504634
    , at *2 (D.D.C. Aug. 16, 2022). The U.S. Court of Appeals
    for the Fourth Circuit has previously held that RFC formulations with vague language do not meet
    this standard. In Thomas, the Fourth Circuit remanded a case where the ALJ limited the claimant
    to work that did not “requir[e] a production rate or demand pace” because the phrase was not a
    common, vocationally relevant functional limitation. 916 F.3d at 312. Because (1) the court was
    not certain of the precise limitations that were created by the phrase in the claimant’s RFC and (2)
    the ALJ did not explain what he meant by the phrase, the court determined that the phrase’s
    ambiguity frustrated its ability to conduct meaningful appellate review. Id.
    Unlike in Thomas, the ALJ here provided enough information for this Court to understand
    “production rate for pace of work.” “Production rate for pace of work” is most analogous to the
    phrase addressed in Johnson v. Saul, No. 19–cv–3829–RCL, 
    2021 WL 411202
    , at *6 n.5 (D.D.C.
    Feb. 5, 2021). In Johnson, the plaintiff objected to the ALJ’s use of the term “non-production rate
    pace of work,” claiming that the phrase was too vague to determine whether the ALJ properly
    accounted for the plaintiff’s concentration, persistence, and pace (“CPP”) limitations. 
    Id.
     On
    review, the district court rejected that argument, finding that the phrase clearly precluded work
    12
    that included production goals. 
    Id.
     Although the court ultimately found that the ALJ did not
    adequately capture plaintiff’s CPP limitations, that error was not based on the alleged “vagueness”
    of the phrase “non-production rate pace of work.” 
    Id.
    The holding in Johnson is persuasive here when interpreting “production rate for pace of
    work.” Although it may have been helpful for the ALJ to include additional context, the phrase
    “production rate for pace of work” is not so vague as to preclude meaningful review. Limiting
    Plaintiff to jobs “where there would be no production rate for pace of work” “plainly indicate[s]
    that [P]laintiff is precluded from work that includes production goals.” AR at 37; 
    2021 WL 411202
    , at *6 n.5. Furthermore, the definition of “production rate pace” appears in the Dictionary
    of Occupation Titles (“DOT”), which explains how the term should be viewed in the context of
    Light Work job positions.7 
    1991 WL 688702
    .
    Plaintiff cites to several cases that mention similar, but not identical, phrases and asserts
    that they are analogous to the phrase at issue in this case.8 These cases are unpersuasive. For one,
    none of the cases involve the phrase “production rate for pace of work.” Second, none of the
    phrases in the other cases Plaintiff cites appear in the DOT, a point that Plaintiff fails to address.
    7
    The DOT explains that a job should be considered Light Work when, among other
    requirements, the job “requires working at a production rate pace entailing the constant pushing
    and/or pulling of materials even though the weight of those materials is negligible.” 
    1991 WL 688702
     (emphasis added). The DOT goes on to note that “[t]he constant stress and strain of
    maintaining a production rate pace, especially in an industrial setting, can be and is physically
    demanding of a worker even though the amount of force exerted is negligible.” 
    Id.
     (emphasis
    added).
    8
    In addition to the phrase at issue in Thomas, Plaintiff also relies on Perry v. Berryhill, 
    765 F. App’x 869
    , 872 (4th Cir. 2019) (“non-production oriented work setting”); Geneva W. v.
    Comm’r, Soc. Sec. Admin, No. CV SAG–18–1812, 
    2019 WL 3254533
    , at *3 (D. Md. July 19,
    2019) (“production pace or strict production quotas”); Yvonne M. v. Comm’r, Soc. Sec. Admin.,
    No. CV 18–2034–RDB, 
    2019 WL 2058834
    , at *2 (D. Md. May 9, 2019) (“work environment free
    of fast-paced production requirements”); Mirlin T. v. Kijakazi, No. 20–cv–00960 (RJL/GMH),
    
    2021 WL 9217635
    , at *9 (D.D.C. Aug. 24, 2021) (“without fast pace or strict production quotas”).
    13
    ECF No. 12–1 at 6–9; ECF No. 18 at 2–3. Because the ALJ’s use of the phrase “no production
    rate for pace of work” is “common enough for [the Court] to know what [it] mean[s] without
    elaboration,” the Court can meaningfully review the RFC the ALJ has crafted. Geneva W. v.
    Comm’r, Soc. Sec. Admin., No. 18–1812, 
    2019 WL 3254533
    , at *3 (D. Md. July 19, 2019) (internal
    citation omitted).
    B. THE ALJ PERFORMED A PROPER FUNCTION-BY-FUNCTION ASSESSMENT                         OF THE
    PLAINTIFF’S ABILITY TO PERFORM WORK-RELATED ACTIVITIES
    Plaintiff claims that the ALJ did not perform a proper function-by-function analysis of
    Plaintiff’s ability to perform work-related activities. ECF No. 12–1 at 13. Plaintiff relies
    principally on Dowling v. Comm’r of SSA, 
    986 F.3d 377
    , 387–88 (4th Cir. 2021), to argue that the
    ALJ erred by failing to follow the RFC analysis order prescribed by the Fourth Circuit. 
    Id. at 14
    .
    Defendant maintains that the ALJ’s RFC analysis provided a logical explanation of Plaintiff’s
    ability to perform a reduced range of medium exertional work in light of Plaintiff’s physical
    impairments. ECF No. 14 at 24–25. Defendant further claims that Dowling is both nonbinding
    and inapposite. 
    Id.
     at 23–24.
    An RFC analysis must include “a narrative discussion describing how the evidence
    supports each conclusion.” Johnson v. Astrue, No. CIV.A 11–00788 ABJ/DAR, 
    2012 WL 3292416
     (D.D.C. Aug. 12, 2012). In the analysis, the ALJ must build a logical bridge from the
    evidence to his conclusion about the Plaintiff’s RFC. 
    Id.
     (citing Banks v. Astrue, 
    537 F.Supp.2d 75
    , 84 (D.D.C. 2008)). As Plaintiff has emphasized, the Fourth Circuit has held that an ALJ’s
    RFC analysis should follow a specific order. Namely, RFC analyses must begin with (1) the
    evidence, followed by (2) a logical explanation, and ending with (3) a conclusion. Dowling, 986
    F.3d at 388; Thomas, 916 F.3d at 311. Importantly, however, “Dowling stops short of ‘adopt[ing]
    a per se rule requiring remand where the ALJ does not perform an explicit-function-by-function
    14
    analysis.’” Jamil D. v. Kijakazi, No. 21–cv–464 (GMH), 
    2022 WL 910334
    , at *11 n.10 (D.D.C.
    Sept. 29, 2022) (quoting Mascio v. Colvin, 
    780 F.3d 632
    , 636 (4th Cir. 2015)).
    Here, the ALJ’s failure to strictly follow the Fourth Circuit’s “proper RFC analysis order”
    does not warrant remand. 
    Id.
     at 387–88. The ALJ began his RFC assessment by concluding that
    Plaintiff can perform medium work with certain limitations. AR at 37. After finding that Plaintiff
    had the RFC to perform medium work with certain limitations, the ALJ proceeded to identify
    Plaintiff’s physical and mental limitations. AR at 37–38. Plaintiff specifically claims that the ALJ
    failed to explain how Plaintiff would be able to perform medium work activity given his lower
    extremity impairments. ECF No. 12–1 at 16. The ALJ, however, acknowledged that Plaintiff’s
    cerebral palsy diagnosis impacts Plaintiff’s ability to walk. 
    Id.
     The ALJ then noted that Plaintiff
    is still able to overcome the challenges he faces when walking to occasionally play pickup
    basketball, groom himself, and do his own laundry. 
    Id.
     Although the ALJ recognized Plaintiff’s
    various physical impairments, the ALJ stated that Plaintiff’s statements about the intensity,
    persistence, and limiting effects of his symptoms are inconsistent with the objective evidence
    which suggests they are not disabling. AR at 38. The ALJ then noted that Plaintiff had normal
    motor skills for his age. AR at 39. Furthermore, Plaintiff had a normal stance and used no assistive
    device to walk or squat. AR at 38. Plaintiff had no signs of any joint or cervical abnormalities.
    AR at 38. Moreover, Plaintiff had normal reflexes, normal grip strength, normal range of motion
    in his spine, and full range of motion of his hips. AR at 38.
    Plaintiff also takes issue with the ALJ’s decision not to include any limitation on Plaintiff’s
    ability to stand and/or walk, despite Dr. Elizabeth Nolte’s opinion that Plaintiff should “avoid
    prolonged walking, walking on uneven surfaces, and climbing ladders.” ECF No. 12–1 at 16
    Plaintiff argues that the ALJ failed to explain his “implicit rejection” of Dr. Nolte’s opinions. 
    Id.
    15
    Plaintiff’s arguments are unavailing for two reasons. First, although an ALJ is required to
    explain his logical reasoning for disregarding portions of a medical opinion, he is not obligated to
    accept every part of a medical opinion, even if he finds the opinion persuasive. Patricia T. v.
    Kijakazi, No. 21–cv–1028, 
    2022 WL 3583634
    , at *34–35 (D.D.C. Aug. 22, 2022); see also Long
    v. Berryhill, No. 18–cv–1146, 
    2019 WL 1433077
    , at *11–12 (E.D.N.Y. Mar. 29, 2019). Here,
    there is no evidence that the ALJ “implicitly rejected” Dr. Nolte’s opinions. The ALJ explained
    that he would “not defer or give any specific evidentiary weight, including controlling weight, to
    any prior administrative medical finding(s) or medical opinion(s),” including those from Plaintiff’s
    treating sources, like Dr. Nolte. AR at 40. The ALJ then mentioned that Dr. Nolte opined that
    Plaintiff had only mild limitations in walking, climbing, and squatting. AR at 41. Contrary to
    Plaintiff’s claims, these mild limitations are consistent with the ALJ’s RFC stating that Plaintiff
    could perform medium work with certain limitations. AR at 37.
    Second, the ALJ is required to determine the most a claimant can do despite his potential
    limitations. 
    20 C.F.R. § 416.946
     (emphasis added). Although the ALJ found Dr. Nolte’s opinion
    persuasive, the ALJ adequately explained why objective evidence reflected that Plaintiff’s
    symptoms are not disabling.9 After a lengthy discussion of the evidence and Plaintiff’s walking
    limitations, the ALJ provided a sufficient narrative discussion of the evidence. AR at 37–41.
    C. THE ALJ FAILED TO ADEQUATELY CAPTURE PLAINTIFF’S MENTAL LIMITATIONS                        IN
    CONCENTRATION, PERSISTENCE, AND PACE IN THE RFC AND HYPOTHETICALS
    Plaintiff argues that the ALJ failed to include any limitation on concentration, persistence,
    or pace (“CPP”) in either the RFC assessment or the hypothetical questions posed to the vocational
    9
    For example, although Plaintiff testified that he could not walk around for too long and his
    left leg occasionally gives out on him, Plaintiff did not use an assistive device to ambulate. AR at
    40. Furthermore, Plaintiff’s stance and range of spine motion were normal. AR at 39. Plaintiff
    had full range of motion of his hips, and his joints were stable and non-tender. 
    Id.
    16
    expert. ECF No. 12–1 at 9. Plaintiff primarily relies on Mascio v. Colvin to support this argument.
    
    780 F.3d at 638
     (holding that “an ALJ does not account ‘for a claimant’s limitations in
    concentration, persistence, and pace by restricting the hypothetical question to simple, routine
    tasks or unskilled work’”) (quoting Winschel v. Comm’r of Soc. Sec., 
    631 F.3d 1176
    , 1180 (11th
    Cir.)). In response, Defendant attempts to distinguish Mascio from this case and claims that the
    ALJ accounted for Plaintiff’s CPP limitations in the RFC by limiting Plaintiff to simple tasks, tasks
    repetitive in nature, and minimal social interactions. ECF No. 14 at 21–23.
    When posing hypothetical questions to a vocational expert, the ALJ must accurately
    describe the claimant’s impairments so the expert may adequately assess whether jobs exist for the
    claimant in the national economy. See Butler, 
    353 F.3d at 1005
    ; Petty v. Colvin, 
    204 F. Supp. 3d 196
    , 205 (D.D.C. 2016). Moderate limitations in CPP affect a plaintiff’s ability to sustain focused
    attention and concentration long enough to complete tasks in common work settings on a timely
    basis. See Johnson, 
    2021 WL 411202
    , at *6; Petty, 204 F. Supp. 3d at 206 (D.D.C. 2016). In
    Petty, this Court adopted the view of most federal courts of appeal and held that an ALJ does not
    properly account for a claimant’s limitations in CPP by restricting hypothetical claimants to
    simple, routine tasks or unskilled work. 204 F. Supp. 3d at 206. As the Court held, “[f]ailure to
    accurately describe a claimant’s impairments can serve as grounds for reversal because it
    undermines the expert’s testimony that a claimant can perform other work.” Id. at 205 (citing
    Butler, 
    353 F.3d at 1006
    ).
    As previously explained, however, there is no need to remand if the ALJ commits a
    harmless error. Johnson, 
    2021 WL 411202
    , at *6; see supra p. 10. An error related to CPP
    limitations is harmless if it meets either of two prongs: (1) medical evidence supports that claimant
    can engage in simple, routine tasks or unskilled work despite limitations in CPP, and the disputed
    17
    hypothetical is limited to include only unskilled work; or (2) the hypothetical implicitly accounts
    for claimant’s limitations in CPP. See Johnson, 
    2021 WL 411202
    , at *6; Petty, 204 F. Supp. 3d at
    206; McIntyre v. Colvin, 
    758 F.3d 146
    , 152 (2d Cir. 2014).
    Here, neither the ALJ’s hypothetical questions to the vocational expert nor the RFC
    adequately capture Plaintiff’s moderate CPP limitations. Much like in Petty, limiting Plaintiff’s
    work to simple, routine, and repetitive tasks does not adequately account for Plaintiff’s moderate
    CPP limitations because “the ability to perform simple tasks differs from the ability to stay on
    task.” 204 F. Supp. 3d at 206 (quoting Mascio v. Astrue, 
    780 F.3d 632
    , 638 (4th Cir. 2015)).
    Notably, the ALJ did not mention Plaintiff’s inability to stay on task in either of the hypothetical
    questions posed, AR at 78–79, and the RFC makes no mention of Plaintiff’s mental limitations.
    AR at 37.
    Defendant argues that, even if the ALJ’s hypothetical questions and RFC insufficiently
    accounted for Plaintiff’s CPP limitations, any such error is harmless. Defendant emphasizes that
    the ALJ’s RFC limited Plaintiff’s interactions with others, only required Plaintiff to make
    occasional judgments or decisions, and limited Plaintiff to occasional changes in the work setting
    to reduce distractions. ECF No. 14 at 21–23. None of these limitations have anything to do with
    whether Plaintiff can perform certain job tasks with moderate limitations in CPP. Moreover, the
    ALJ’s errors do not meet either of the requirements to be considered harmless. First, the ALJ did
    not restrict his hypothetical questions or RFC to unskilled work. AR at 78–79, 37; see also
    Johnson, 
    2021 WL 411202
    , at *6. Second, the ALJ’s hypotheticals do not “implicitly account[]”
    for Plaintiff’s CPP limitations. Although Defendant claims that the record “does not support
    additional mental limitations,” this argument resembles the flawed argument made in Petty. There,
    the Court held that the absence of evidence is improper to support a finding that Plaintiff can
    18
    engage in simple, routine, low stress tasks. 204 F. Supp. 3d at 207–08. In the absence of
    affirmative evidence showing that Plaintiff can perform work despite moderate CPP limitations,
    the Defendant has failed to meet her burden of proving that the ALJ’s error was harmless.
    CONCLUSION
    For the foregoing reasons, Plaintiff’s Motion for Reversal, ECF No. 12–1, is GRANTED
    IN PART with respect to the ALJ’s failure to adequately account for and capture Plaintiff’s CPP
    limitations.   That issue is REMANDED to the Social Security Administration for further
    proceedings consistent with this memorandum opinion. Plaintiff’s Motion for Reversal, ECF No.
    12–1, is DENIED IN PART on all other claims. For the reasons also stated above, Defendant’s
    Motion for Judgment of Affirmance, ECF No. 14, is GRANTED IN PART and DENIED IN
    PART.
    SO ORDERED.
