income benefits. Exercising jurisdiction under 28 U.S.C. § 1291 and reviewing de
novo, see Woods v. Kijakazi, 32 F.4th 785, 788 (9th Cir. 2022), we affirm.
1. An ALJ cannot reject a medical opinion “as unsupported or
inconsistent without providing an explanation supported by substantial evidence.”
Id. at 792. “Substantial evidence is more than a mere scintilla,” but “means only
such relevant evidence as a reasonable mind might accept as adequate to support a
conclusion.” Ford v. Saul, 950 F.3d 1141, 1154 (9th Cir. 2020) (cleaned up).
Additionally, “the ALJ must assess the persuasiveness of each medical opinion
after considering specified factors.” Stiffler v. O’Malley, 102 F.4th 1102, 1106 (9th
Cir. 2024) (citations omitted). “Consistency and supportability are the most
important factors.” Id. (citations omitted). “Consistency means the extent to which
a medical opinion is ‘consistent . . . with the evidence from other medical sources
and nonmedical sources in the claim.’” Woods, 32 F.4th at 792 (quoting 20 C.F.R.
§ 404.1520c(c)(2)). “Supportability means the extent to which a medical source
supports the medical opinion by explaining the ‘relevant . . . objective medical
evidence.’” Id. at 791–92 (quoting 20 C.F.R. § 404.1520c(c)(1)). “Ultimately, the
ALJ must articulate how persuasive it finds all of the medical opinions from each
doctor or other source, and explain how it considered the supportability and
consistency factors in reaching these findings.” Stiffler, 102 F.4th at 1106 (internal
quotation marks and citation omitted).
2 24-6250
The ALJ considered the opinions of Drs. Beth Liu, Merry Alto, Howard
Platter, and Garima Ajmani and found “these opinions unpersuasive because they
are inconsistent with the objective medical evidence” and Dunn’s “demonstrated
functioning and are unsupported by treatment notes, exam findings, or other
objective evidence.” The ALJ thus assessed the persuasiveness of the medical
opinions by considering the consistency and supportability factors. See Woods, 32
F.4th at 792.
The ALJ observed that the opinions of Drs. Liu, Alto, Platter, and Ajmani
were inconsistent with and unsupported by objective medical evidence. In rejecting
the opinions of Drs. Liu, Alto, and Platter, the ALJ found that Dunn “presents in no
acute distress with a normal gait; normal cardiovascular, pulmonary, and
musculoskeletal exams; and mild lower extremity edema at other exams.” The
record cited by the ALJ supports these observations and reflects that Dunn was
repeatedly observed in 2020 and 2021 as being “in no distress” upon physical
examination in medical appointments. Since the objective medical evidence
indicated that Dunn’s physical limitations were not as severe as indicated by the
doctors’ opinions, substantial evidence supports the ALJ’s rejection of those
opinions. See Kitchen v. Kijakazi, 82 F.4th 732, 740 (9th Cir. 2023) (holding that
“[s]ubstantial evidence supports the ALJ’s finding” that a doctor’s opinion “was
not persuasive” because “objective observations during office visits counter the
3 24-6250
extremeness of [the doctor’s] evaluation”); see also Woods, 32 F.4th at 794
(holding that the ALJ “reasonably rejected” a doctor’s opinion where the opinion
was inconsistent with “treatment notes”).
Dunn highlights other medical evidence in the record, such as Dunn’s
morbid obesity, chronic lower back pain, lower extremity edema, and knee
problems, along with treatment notes from a medical appointment indicating that
Dunn was in “obvious pain.” But where, as here, the evidence “is susceptible to
more than one rational interpretation, it is the ALJ’s conclusion that must be
upheld.” Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005) (citation omitted).
The ALJ also observed that Dunn’s documented activity level was
inconsistent with these doctors’ opinions. In rejecting the opinions of Drs. Liu,
Alto, and Platter, the ALJ found that the “severity of their opined limitations are
not consistent with the many reports throughout the record of [Dunn’s] engaging in
weightlifting, going to the gym, and improved symptoms through exercise.” The
record cited by the ALJ supported these propositions and reflects that Dunn
maintained an exercise routine involving cardio and resistance training three times
per week, usually for two hours each time throughout 2021. Since Dunn’s recorded
activity level indicates greater functioning than opined by the doctors, substantial
evidence supported the ALJ’s rejection of those doctors’ opinions. See Stiffler, 102
F.4th at 1108 (holding that the ALJ’s rejection of a doctor’s opinion was
4 24-6250
“supported by substantial evidence” where the claimant’s “documented activities
suggest a higher range of functioning than those assessed by [the doctor]”).
Dunn highlights evidence that he experienced knee injuries while exercising
between July 2021 and January 2022. But the record also indicates that Dunn
recovered from those knee injuries, as he was in “[n]o pain” and “in no acute
distress” upon physical examination in July 2022. Where, as here, the evidence “is
susceptible to more than one rational interpretation, it is the ALJ’s conclusion that
must be upheld.” Burch, 400 F.3d at 679 (citation omitted). Dunn further argues
that, even if the ALJ were correct to conclude that his exercise routine was
inconsistent with the medical opinions, subsequent improvement is not a valid
reason to discount a medical opinion. But an ALJ may consider whether new
evidence received “after the medical source made his or her medical opinion . . .
makes the medical opinion . . . more or less persuasive,” and the ALJ properly did
so here. See 20 C.F.R. 404.1520c(c)(5).
Because we find that the ALJ provided legally sufficient reasons for
rejecting these medical opinions, we reject this claim.
AFFIRMED.
