The Honorable William Horsley Orrick, United States District Judge
for the Northern District of California, sitting by designation.
Commissioner of Social Security’s denial of his application for disability insurance
benefits under Title II of the Social Security Act, 42 U.S.C. §§ 401-434. We have
jurisdiction under 28 U.S.C. § 1291. We review the district court’s decision
affirming the ALJ’s denial of benefits de novo, and the ALJ’s denial of benefits
“for substantial evidence or legal error.” Farlow v. Kijakazi, 53 F.4th 485, 487
(9th Cir. 2022). We affirm.
1. We assume that Dr. Hopfenbeck’s evaluation of Quayle is part of the
administrative record that we consider in reviewing the Commissioner’s decision.
See Brewes v. Comm’r of Soc. Sec. Admin., 682 F.3d 1157, 1163 (9th Cir. 2012).
Notwithstanding Dr. Hopfenbeck’s evaluation, substantial evidence supports the
Commissioner’s determination that Quayle had the residual functional capacity
(RFC) to perform light work, see 20 C.F.R. § 404.1567(b), and detailed tasks.
According to multiple physicians who reviewed Quayle’s medical history,
Quayle’s physical impairments required him to alternate between sitting and
standing during the day, but did not prevent him from working altogether. The
physicians’ opinions were consistent with medical records demonstrating that
Quayle’s physical faculties, such as muscle strength, appeared largely intact; that
epidural steroid injections and other medications improved his symptoms, see
Berry v. Astrue, 622 F.3d 1228, 1236 (9th Cir. 2010); and that he regularly
engaged in light physical activity, such as performing chores and walking, see
2 24-4649
Thomas v. Barnhart, 278 F.3d 947, 959 (9th Cir. 2002).
Similarly, several psychologists determined that Quayle’s mental health
conditions did not prevent him from performing work that involved limited contact
with coworkers and the public. Their opinions were consistent with medical
records reflecting that Quayle exhibited no cognitive impairment in most areas,
including memory, concentration, speech, and linear thinking; and that medication
somewhat improved his depressive symptoms. The fact that Quayle continuously
worked for eight years before filing for benefits, notwithstanding that his physical
impairments and mental-health conditions dated back to 2007, further supported
the Commissioner’s determination. Ford v. Saul, 950 F.3d 1141, 1156 (9th Cir.
2020) (“An ALJ may consider any work activity, including part-time work, in
determining whether a claimant is disabled . . . .”).
That Dr. Hopfenbeck evaluated Quayle differently did not require the
Commissioner to accept Dr. Hopfenbeck’s conclusions. See Ford, 950 F.3d at
1155 (explaining that the Commissioner need not accept “the opinion of an
examining doctor [that] is contradicted by another doctor”). Dr. Hopfenbeck, the
other medical professionals, and the Commissioner relied on largely the same
records, reflecting longstanding medical conditions. At best, Dr. Hopfenbeck
offers an alternative interpretation of the evidence that might support Quayle’s
disability claim, which is insufficient to overturn the Commissioner’s decision.
3 24-4649
See Coleman v. Saul, 979 F.3d 751, 756 (9th Cir. 2020) (“[W]e will not disturb the
ALJ’s differing rational interpretation where the ALJ’s interpretation is adequately
supported.”).
2. The ALJ did not err in partially discrediting Quayle’s testimony
regarding the severity of his symptoms. An ALJ may discredit a claimant’s
testimony about the severity of his or her symptoms “by offering specific, clear
and convincing reasons for doing so.” Ferguson v. O’Malley, 95 F.4th 1194, 1199
(9th Cir. 2024) (quoting Garrison v. Colvin, 759 F.3d 995, 1014-15 (9th Cir.
2014)). Here, the ALJ explained that Quayle’s statements “concerning the
intensity, persistence, and limiting effects of [his] symptoms” were not consistent
with his “treatment record,” nor with “contemporaneous reports of actual
functioning.” See Burrell v. Colvin, 775 F.3d 1133, 1137 (9th Cir. 2014)
(“Inconsistencies between a claimant’s testimony and the claimant’s reported
activities provide a valid reason for an adverse credibility determination.”). The
ALJ then described the records and evidence supporting the ALJ’s conclusion,
including those discussed above. The ALJ also found that inconsistencies between
Quayle’s testimony and the record regarding his cannabis use undermined his
credibility. See Tonapetyan v. Halter, 242 F.3d 1144, 1148 (9th Cir. 2001) (“In
assessing the claimant’s credibility, the ALJ may use ordinary techniques of
credibility evaluation, such as considering . . . inconsistent statements in her
4 24-4649
testimony” (internal quotation marks and citation omitted)). The ALJ’s
explanation for only partially crediting Quayle’s testimony was sufficiently
specific, clear and convincing, and supported by substantial evidence.
3. Quayle is not entitled to a remand under sentence six of 42 U.S.C.
§ 405(g). Sentence six “applies only to new evidence that is not part of the
administrative record and is presented in the first instance to the district court.”
682 F.3d at 1164. Quayle concedes that Dr. Hopfenbeck’s opinion was part of the
administrative record.
AFFIRMED.
