MEMORANDUM*
KILOLO KIJAKAZI, Acting Commissioner
of Social Security,
Defendant-Appellee.
Appeal from the United States District Court
for the Western District of Washington
Michelle L. Peterson, Magistrate Judge, Presiding
Submitted December 6, 2023**
Seattle, Washington
Before: McKEOWN, N.R. SMITH, and SANCHEZ, Circuit Judges.
Appellant Marcellina M. MacArthur seeks review of a district court order
affirming a decision by an Administrative Law Judge (“ALJ”) denying MacArthur
for a Period of Disability and Disability Insurance Benefits, and for Supplemental
*

The panel unanimously concludes this case is suitable for decision
without oral argument. See Fed. R. App. P. 34(a)(2).
Security Income (“SSI”). We have jurisdiction under 28 U.S.C. § 1291. We
review the district court’s order affirming the ALJ’s denial of benefits de novo, and
will not overturn the denial “unless it is either not supported by substantial
evidence or is based upon legal error.” Luther v. Berryhill, 891 F.3d 872, 875 (9th
Cir. 2018). We affirm.
When determining eligibility for benefits, an “ALJ must consider all medical
opinion evidence.”1 Tommasetti v. Astrue, 533 F.3d 1035, 1041 (9th Cir. 2008)
(citing 20 C.F.R. § 404.1527(b)). An ALJ is not required to take all medical
opinions at face value, and may properly reject a contradicted medical opinion by
setting forth “specific and legitimate reasons supported by substantial evidence in
the record.” Lester v. Chater, 81 F.3d 821, 830 (9th Cir. 1995) (as amended)
(internal quotation marks omitted). “The ALJ can meet this burden by setting out a
detailed and thorough summary of the facts and conflicting clinical evidence,
stating his interpretation thereof, and making findings.” 2 Magallanes v. Bowen,
881 F.2d 747, 751 (9th Cir. 1989) (internal quotation marks and citation omitted).

Because MacArthur applied for benefits prior to March 27, 2017, the revised
regulations regarding the evaluation of medical opinions do not apply. See Woods
v. Kijakazi, 32 F.4th 785, 789 (9th Cir. 2022).
2
MacArthur’s bare contention that the ALJ did not properly evaluate the findings
and opinion of Dr. Nagaraj is not supported by argument. We therefore deem the
contention forfeited. See Miller v. Fairchild Indus., Inc., 797 F.2d 727, 738 (9th
Cir. 1986).

1. The ALJ gave specific and legitimate reasons for discounting Dr.
Morgan’s mental health opinion from September 2015. The ALJ found Dr.
Morgan’s observations of marked limitations, depressed mood and limited recall
were inconsistent with the opinions of other mental health examiners, Dr. Alvord
and Dr. Ryan, who noted unimpaired memory and concentration, normal affect,
and appropriate interactions. The ALJ also noted MacArthur’s normal presentation
in many other medical appointments, and her ability to take college classes and
keep a regular schedule. See Morgan v. Comm’r of Soc. Sec. Admin., 169 F.3d
595, 600–02 (9th Cir.1999) (inconsistencies between a physician’s opinion and a
claimant’s daily activities can be a specific and legitimate reason to discount the
treating physician’s opinion). The ALJ found that Dr. Morgan’s opinion was also
inconsistent with evidence of MacArthur’s improvement under a routine and
conservative course of mental health treatment. Substantial evidence in the record
supports the ALJ’s specific findings.
2. The ALJ gave specific and legitimate reasons for its partial rejection
of Dr. Alvord’s mental health opinion of “mild-moderate impairment in adaptive
functioning,” finding this conclusion internally inconsistent with the observation
that MacArthur had no mental health treatment, normal concentration and memory,
and only mild difficulties with activities of daily living. See id. at 603 (internal
inconsistencies within a physician’s report are relevant evidence in determining the
3
weight of a medical opinion). The ALJ also found Dr. Alvord’s opinion
inconsistent with other observations of normal memory and concentration, a
routine and conservative course of treatment, and her ability to maintain a daily
schedule.
3. The ALJ’s decision to give Dr. Ryan’s mental health opinion “some
but less than great weight” is supported by specific and legitimate reasons based on
substantial evidence in the record. The ALJ’s decision to discount Dr. Ryan’s
functional adaptive limitation as vague is supported by clear and legitimate reasons
found in the record. See 20 C.F.R. § 404.1520b(b) (ambiguous evidence is
considered inconsistent). The ALJ found Dr. Ryan’s schedule limitation
inconsistent with MacArthur’s “report of getting good grades in college classes,
and her work activity in 2016-2021, which suggest that her mental symptoms cause
little interference in maintaining a daily or weekly schedule.” See Morgan, 169
F.3d at 600-02. The ALJ did not err in finding that MacArthur’s ability to engage
in activities like school and work was inconsistent with Dr. Ryan’s schedule
limitation.
4. The ALJ did not err in not addressing Dr. Brzusek’s June 2010
evaluation of MacArthur’s workplace compensation claim. Dr. Brzusek’s findings
are consistent with the ALJ’s residual functional capacity (“RFC”) determination
that MacArthur was limited to slower-pace, sedentary work. Nor did the ALJ err
4
in discounting the opinion of vocational rehabilitation counselor Ms. Smith. An
ALJ may discount lay witness opinion evidence by providing “reasons germane to
each witness for doing so.” Molina v. Astrue, 674 F.3d 1104, 1111 (9th Cir. 2012)
(internal quotation marks and citation omitted). The ALJ provided germane
reasons for discounting Ms. Smith’s opinion based on inconsistencies with record
evidence of limited pain behavior observations, largely normal strength, improved
headache and migraine symptoms, conservative treatment, lack of behavioral
difficulties, and ability to take college classes and work.
5. The ALJ provided clear and convincing reasons for discounting
MacArthur’s subjective testimony regarding the intensity, persistence, and limiting
effects of her alleged debilitating pain related to her fibromyalgia and neuropathy.
The ALJ found that the objective medical evidence did not support MacArthur’s
claims and was inconsistent with allegations of disabling limitations. MacArthur’s
conditions improved with a routine and conservative course of treatment, and her
ability to maintain a college schedule and daily activities were inconsistent with
her alleged limitations. See Carmickle v. Comm’r, Soc. Sec. Admin., 533 F.3d
1155, 1161 (9th Cir. 2008) (“Contradiction with the medical record is a sufficient
basis for rejecting the claimant’s subjective testimony”).
The ALJ carefully reviewed MacArthur’s treatment history post-surgeries
and her overall improvement and pain management. Although MacArthur did not
5
seek a referral to a fibromyalgia specialist until 2013, Dr. Pfeiffer found in 2011
that she had only mild to moderate issues with this impairment, even without
medication. MacArthur also noted improvement in her condition when she did
take medication after 2013. While this improvement was not uniform, she was
able to maintain a regular work and class schedule during the period of claimed
disability. Further, the ALJ did not discount MacArthur’s testimony in full, and
accounted for her physical and mental limitations in the RFC. See id. at 1163.
AFFIRMED.
