2 Opinion of the Court 21-12148
Before WILLIAM PRYOR, Chief Judge, LUCK and LAGOA, Cir-
cuit Judges.
WILLIAM PRYOR, Chief Judge:
This appeal requires us to decide whether an administrative
law judge should have applied a new regulation about the proper
weight to give the medical opinions of a disability claimant’s treat-
ing physicians. The new regulation, 20 C.F.R. § 404.1520c (2017),
abrogated the “treating-physician rule” first developed by this and
other courts of appeals. The treating-physician rule instructed ad-
ministrative law judges to defer to the medical opinions of treating
physicians in the determination of whether an individual is disabled
under the Social Security Act. The new regulation instructs admin-
istrative law judges to give a treating physician’s opinion no defer-
ence and instead to weigh medical opinions based on their persua-
siveness. Because the new regulation validly abrogated the treat-
ing-physician rule and applied to Harner’s claim, we affirm.
I. BACKGROUND
In April 2017, Zinta Harner applied for disability benefits.
She alleged that, as of August 2016, she was unable to work because
of degenerative disc disease, bulging and herniated discs, other
spine issues, fatigue, migraines, asthma, fatty liver, and food aller-
gies. Before August 2016, Harner had worked as a medical-office
receptionist and a travel agent. Her application for benefits was first

21-12148 Opinion of the Court 3
denied in August 2017. Harner then requested a hearing before an
administrative law judge, which took place in April 2019.
At the hearing, the administrative law judge considered the
administrative record and Harner’s medical records, which in-
cluded opinions from many different medical professionals. Harner
emphasized the opinions of three of these medical professionals:
Doctor Chindalore, Doctor Johnson, and Nurse Practitioner
Pettry. Chindalore was Harner’s rheumatologist who treated
Harner’s fibromyalgia. Johnson was Harner’s neurosurgeon who
treated Harner for her back pain and performed Harner’s 2017 spi-
nal fusion surgery. Both Chindalore and Johnson expressed medi-
cal opinions that Harner’s impairments would prevent her from
working and impact her daily activities. They both stated that
Harner became unable to work on August 5, 2016, and that she
could stand and walk for less than two hours per day, sit for less
than two hours per day, and sit for only 15 minutes at a time before
needing to change position. Pettry treated Harner for depression
and anxiety and stated that Harner’s emotional disability limited
her ability to “cop[e] with what would otherwise be considered
normal, but significant day to day situations.”
The administrative law judge also heard testimony from
Harner and a vocational expert. Harner testified about her past
work experiences, how her pain affected her work, and her day-to-
day life. The vocational expert answered a series of hypotheticals
about what kinds of work an individual with Harner’s background
and different sets of physical limitations could complete.

4 Opinion of the Court 21-12148
The administrative law judge denied Harner’s application
on the ground that she could perform both her past relevant work
and unskilled light work. To make this determination, the admin-
istrative law judge followed the multi-step evaluation process es-
tablished by the Commissioner. See 20 C.F.R. § 404.1520(a) (2020).
He found that, although three of Harner’s impairments (her spine
disorders, fibromyalgia, and migraines) qualified as “severe,” id.
§ 404.1520(a)(4)(ii), her impairments did not “meet[] or equal[]” the
severity of an impairment listed in the regulations, id.
§ 404.1520(a)(4)(iii). The administrative law judge also found that
Harner had “the residual functional capacity to perform light
work” with certain restrictions to account for Harner’s impair-
ments, see id. § 404.1520(a)(4)(iv), (e), and that with her residual
functioning capacity, Harner could perform her past relevant work
as well as other jobs that require unskilled light work, see id.
§ 404.1520(a)(4)(v).
In his analysis of Harner’s residual functioning capacity, the
administrative law judge did not give the medical opinions of
Harner’s treating physicians deference or controlling weight. In-
stead, the administrative law judge considered all the medical opin-
ions “in accordance with the requirements of [section] 404.1520c.”
See id. § 404.1520c. The administrative law judge “d[id] not find”
the assessments of Chindalore, Johnson, and Pettry “persuasive, as
they [we]re not supported by or consistent with the medical evi-
dence, particularly the evidence demonstrating improvement and
resolution of [Harner’s] leg pain following back surgery and
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 5 of 13
21-12148 Opinion of the Court 5
conservative care.” He explained that “[t]he record provided mul-
tiple clinical entries documenting that the pain symptoms were sta-
ble on her treatment regimen” and “indicated improvement in her
mental health.” But the administrative law judge did find that the
opinions of the state agency consultants that Harner was “capable
of light work with some postural, manipulative, and environmen-
tal restrictions” were “persuasive and consistent with the objective
medical evidence.” The administrative law judge included an addi-
tional limitation for Harner’s need to alternate sitting and standing
in the light of her testimony and medical evidence submitted post-
consultation.
In the light of this analysis, the administrative law judge con-
cluded that Harner was not disabled under the Act and was not
entitled to disability benefits. The Appeals Council denied Harner’s
request for review. So, the administrative law judge’s decision be-
came the final agency decision. See Doughty v. Apfel, 245 F.3d
1274, 1278 (11th Cir. 2001). Harner filed a complaint seeking re-
view of the administrative law judge’s decision in the district court.
The district court affirmed the decision of the administrative
law judge. The district court determined that section 404.1520c,
and not the treating-physician rule, applied to Harner’s claim. The
district court also concluded that “[u]nder the new regulations, the
[administrative law judge] adequately accounted for his finding
that the medical opinions from Ms. Harner’s treating physicians
were not persuasive” because he “cited to specific pieces of incon-
sistent evidence in the record and pointed out why he believed
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 6 of 13
6 Opinion of the Court 21-12148
[Doctors] Chindalore and Johnson and [Nurse Practitioner] Pettry
provided unsupportable opinions.” The district court further con-
cluded that “[s]ubstantial evidence supports the [administrative law
judge’s] analysis of the medical opinions from Ms. Harner’s treat-
ing physicians.” The district court determined that the administra-
tive law judge did not err in considering Harner’s daily activities in
his residual functioning capacity analysis, that the administrative
law judge properly analyzed Harner’s fibromyalgia, and that there
was substantial evidence in the record that Harner could perform
her past work. Finally, the district court denied Harner’s motion to
remand due to a later finding of disability in October 2020. Harner
appealed.
II. STANDARD OF REVIEW
We review an administrative law judge’s application of the
law de novo. Buckwalter v. Acting Comm’r of Soc. Sec., 5 F.4th
1315, 1320 (11th Cir. 2021).
III. DISCUSSION
Harner argues that our earlier precedents establishing and
applying the treating-physician rule are still good law, notwith-
standing the promulgation of section 404.1520c. “Where, as here,
the statute expressly entrusts the [Commissioner] with the respon-
sibility for implementing a provision by regulation, our review is
limited to determining whether the regulation[] promulgated ex-
ceeded the [Commissioner’s] statutory authority and whether [it
is] arbitrary and capricious.” Heckler v. Campbell, 461 U.S. 458, 466
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 7 of 13
21-12148 Opinion of the Court 7
(1983) (footnote omitted); see also Chevron, U.S.A., Inc. v. Nat.
Res. Def. Council, Inc., 467 U.S. 837, 843–44 (1984) (“If Congress
has explicitly left a gap for the agency to fill, there is an express del-
egation of authority to the agency to elucidate a specific provision
of the statute by regulation. Such legislative regulations are given
controlling weight unless they are arbitrary, capricious, or mani-
festly contrary to the statute.”). Because section 404.1520c falls
within the scope of the Commissioner’s authority and was not ar-
bitrary and capricious, it abrogates our earlier precedents applying
the treating-physician rule.
The Social Security Act conferred “exceptionally broad au-
thority” to the Commissioner “to prescribe standards for applying
certain sections of the . . . Act.” Heckler, 461 U.S. at 466 (internal
quotation marks omitted). This broad authority includes the au-
thority to adopt “reasonable and proper rules and regulations to
regulate and provide for the nature and extent of the proofs and
evidence and the method of taking and furnishing the same” for
adjudicating disability claims. 42 U.S.C. § 405(a). Exercising this
delegated authority, the Commissioner promulgated section
404.1520c.
Before the promulgation of section 404.1520c, administra-
tive law judges were instructed to defer to the medical opinions of
a social security claimant’s treating physicians. This “treating phy-
sician rule . . . was originally developed by Courts of Appeals as a
means to control disability determinations by administrative law
judges under the Social Security Act.” Black & Decker Disability

Plan v. Nord, 538 U.S. 822, 829 (2003). In 1991, the Commissioner
promulgated a regulation that adopted the treating-physician rule.
Id.; see 56 Fed. Reg. 36932 (Aug. 1, 1991) (to be codified at 20 C.F.R.
pts. 404, 416). The regulation required administrative law judges to
“[g]enerally . . . give more weight” to the opinions of treating phy-
sicians unless there was good cause not to do so. 20 C.F.R.
§ 404.1527(d)(2) (1992); see also 20 C.F.R. § 404.1527(c)(2) (2016)
(most recent iteration of the treating-physician-rule regulation).
In 2017, the Commissioner eliminated the treating-physician
rule. 82 Fed. Reg. 5844, 5853 (Jan. 18, 2017) (to be codified at 20
C.F.R. pts. 404, 416). The Commissioner explained that the change
eliminated confusion about the hierarchy of medical sources and
focused on “the persuasiveness of the content of the evidence.” Id.
The Commissioner determined that a change was required due to
the shift away from physicians having a personal relationship with
claimants and toward claimants consulting multiple doctors and
care teams. Id. at 5852–53.
“For claims filed . . . on or after March 27, 2017,” an admin-
istrative law judge must “not defer or give any specific evidentiary
weight, including controlling weight, to any medical opinion(s) or
prior administrative medical finding(s), including those from [a
claimant’s] medical sources.” 20 C.F.R. § 404.1520c(a). Instead, the
new regulation provides several factors for determining what
weight to give a claimant’s proffered medical opinions. Those fac-
tors include the supportability of the medical opinion, its con-
sistency with other record evidence, the physician’s relationship
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 9 of 13
21-12148 Opinion of the Court 9
with the claimant, the physician’s specialty, and other relevant in-
formation, such as the physician’s familiarity with the other record
evidence and with making a claim for disability. Id.
§ 404.1520c(c)(1)–(5).
Section 404.1520c falls within the express delegation to the
Commissioner to “adopt reasonable and proper rules and regula-
tions to regulate and provide for the nature and extent of the proofs
and evidence and the method of taking and furnishing the same”
for adjudicating disability claims. See 42 U.S.C. § 405(a). And alt-
hough the Act instructs administrative law judges to “make every
reasonable effort to obtain from the individual’s treating physician
. . . all medical evidence . . . necessary” to make a proper disability
determination, 42 U.S.C. § 423(d)(5)(B), the Act does not specify
how this evidence is to be weighed. Because section 404.152c falls
within the express delegation and is not “manifestly contrary to the
statute,” see Chevron, 467 U.S. at 844, the regulation did not “ex-
ceed the [Commissioner’s] statutory authority.” See Heckler, 461
U.S. at 466.
Neither is section 404.1520c arbitrary or capricious. The
Commissioner explained her replacement of the treating-physician
rule with an instruction to weigh medical opinions based on their
persuasiveness due to “fundamental changes in healthcare deliv-
ery.” 82 Fed. Reg. at 5853. The Commissioner explained that today
claimants “less frequently develop a sustained relationship with
one treating physician” and often “receive health care from multi-
ple medical sources, such as coordinated and managed care
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 10 of 13
10 Opinion of the Court 21-12148
organizations.” Id. Section 404.1520c “retain[s] the relationship be-
tween the medical source and the claimant as one of the factors we
consider as we evaluate the persuasiveness of a medical opinion”
and “allow[s] an adjudicator to consider an individual’s own medi-
cal source’s medical opinion to be the most persuasive medical
opinion if it is both supported by relevant objective medical evi-
dence and . . . is consistent with other evidence.” Id.; see also 20
C.F.R. § 404.1520c(c)(3). But section 404.1520c also helps to “elim-
inate confusion about a hierarchy of medical sources” that no
longer reflects how most claimants receive health care. See 82 Fed.
Reg. at 5853. The Commissioner “adequately explain[ed] the rea-
sons for [this] reversal of policy,” and so the “change is not invali-
dating.” Nat’l Cable & Telecomms. Ass’n v. Brand X Internet
Servs., 545 U.S. 967, 981 (2005) (internal quotation marks omitted);
see also id. (An “agency . . . must consider . . . the wisdom of its
policy on a continuing basis . . . in response to changed factual cir-
cumstances.”) (first alteration in original) (internal quotation marks
omitted).
That our precedents came before the Commissioner’s regu-
lations does not change our analysis. “A court’s prior judicial con-
struction of a statute trumps an agency construction otherwise en-
titled to Chevron deference only if the prior court decision holds
that its construction follows from the unambiguous terms of the
statute and thus leaves no room for agency discretion.” Id. at 982.
“This principle follows from Chevron itself,” the “premise” of
which “is that it is for agencies, not courts, to fill statutory gaps.”
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 11 of 13
21-12148 Opinion of the Court 11
Id. “A contrary result illogically would wed this circuit to” our ear-
lier decisions “while [other courts] would be bound under Chevron
to defer to the [Commissioner’s] rule.” See Satellite Broad. &
Commc’ns Ass’n of Am. v. Oman, 17 F.3d 344, 348 (11th Cir. 1994).
“Moreover, it would create a rush to the courthouse among parties
wishing to litigate a statute’s meaning before an agency has exer-
cised its” authority. See id.
We have never held that the treating-physician rule is unam-
biguously required by the Act. The rule was first adopted by this
Court in 1982. See Walden v. Schweiker, 672 F.2d 835 (11th Cir.
1982). In Walden, we relied on a decision of our predecessor Court,
Smith v. Schweiker, which explained that “[i]t is not only legally
relevant but unquestionably logical that the opinions, diagnosis,
and medical evidence of a treating physician whose familiarity with
the patient’s injuries, course of treatment, and responses over a
considerable length of time, should be given considerable weight.”
646 F.2d 1075, 1081 (5th Cir. Unit A June 1981). The Smith decision
itself relied on an even earlier decision of our predecessor Court,
Fruge v. Harris, 631 F.2d 1244 (5th Cir. Unit A 1980), which as-
serted that “[u]nless there is good cause shown to the contrary, the
testimony of the treating physician must be accorded substantial
weight,” id. at 1246. No decision of this Court applying the treating-
physician rule purports to interpret the Act, let alone holds that the
Act unambiguously requires the treating-physician rule. See, e.g.,
MacGregor v. Bowen, 786 F.2d 1050, 1053 (11th Cir. 1986); Brough-
ton v. Heckler, 776 F.2d 960, 961–62 (11th Cir. 1985); Wiggins v.

12 Opinion of the Court 21-12148
Schweiker, 679 F.2d 1387, 1389 (11th Cir. 1982). In fact, none of the
courts of appeals that applied the treating-physician rule before the
1991 regulation held that the rule was required by the Act. 56 Fed.
Reg. at 36934 (“None of the circuit courts of appeals has held that
its treating physician rule is required by the Act or the Constitu-
tion.”). Instead, this Court and other courts of appeals engaged in
gap-filling, based on a reasonable understanding of the doctor-pa-
tient relationship, before the Commissioner did the same. See id.
Section 404.1520c applied to Harner’s claim. Harner filed
her disability claim on April 28, 2017, after the effective date for
section 404.1520c. And because section 404.1520 forbids adminis-
trative law judges from “defer[ring] or giv[ing] any specific eviden-
tiary weight, including controlling weight, to any medical opin-
ion(s),” 20 C.F.R. § 404.1520c(a), the administrative law judge did
not err by declining to give more weight to the medical opinions
of Harner’s treating physicians.
Finally, to the extent that Harner mentions other aspects of
the administrative law judge’s decision, she has forfeited any chal-
lenge to them. An appellant is required in her brief to address her
“contentions and the reasons for them, with citations to the author-
ities and parts of the record on which [she] relies.” FED. R. APP. P.
28(a)(8)(A). An appellant forfeits an issue when she “raises it in a
perfunctory manner without supporting arguments and author-
ity.” Sapuppo v. Allstate Floridian Ins. Co., 739 F.3d 678, 681 (11th
Cir. 2014). Harner’s references to the substantiality of the evidence,
the administrative law judge’s analysis of her fibromyalgia, and the
USCA11 Case: 21-12148 Date Filed: 06/27/2022 Page: 13 of 13
21-12148 Opinion of the Court 13
administrative judge’s consideration of her daily activities as
“[d]iminish[ing] the [p]ersuasiveness of [h]er [a]llegations” consist
only of block quotations from and cursory mentions of various de-
cisions of this and other courts. Harner failed to refer to the facts of
her case or to provide any meaningful explanation as to how the
decisions she cites apply to her claim, her arguments are forfeited.
IV. CONCLUSION
We AFFIRM the judgment of the district court.
