Opinion

UNITED STATES DISTRICT COURT WESTERN DISTRICT OF WASHINGTON AT TACOMA Plaintiff, Case No. C26-5203-MLP v. ORDER Defendant. I. INTRODUCTION Plaintiff seeks review of the denial of his application for Supplemental Security Income. Plaintiff contends that the administrative law judge (“ALJ”) erred by misevaluating his testimony and the medical opinion evidence, resulting in an erroneous residual functional capacity (“RFC”) determination. (Dkt. # 10.) The Commissioner filed a response arguing that the ALJ’s decision is free of legal error, supported by substantial evidence, and should be affirmed. (Dkt. # 13.) Plaintiff filed a reply. (Dkt. # 14.) Having considered the ALJ’s decision, the administrative record (“AR”), and the parties’ briefing, the Court AFFIRMS the Commissioner’s final decision and DISMISSES the case with prejudice.1 1 The parties consented to proceed before the undersigned Magistrate Judge. (Dkt. # 2.) Plaintiff was born in 1983, has at least a high school education, and has no past relevant work. AR at 49. In February 2023, he applied for benefits, alleging disability as of November 12, 2012. Id. at 38. His applications were denied initially and on reconsideration, and Plaintiff

requested a hearing. Id. After the ALJ conducted a hearing in April 2025, the ALJ issued a decision finding Plaintiff not disabled. Id. at 38-50. Using the five-step disability evaluation process,2 the ALJ found, in pertinent part, severe impairments of degenerative disc disease, bilateral hip osteoarthritis, migraine, anxiety disorder, depressive disorder, and trauma. AR at 40. The ALJ assessed an RFC for light work with the following limits: occasional climbing of ramps or stairs; no climbing of ladders, ropes, or scaffolds; occasional balancing, stooping, kneeling, and crouching; tolerance for moderate or lower noise; occasional exposure to hazards, including high, exposed places and proximity to moving mechanical parts; ability to understand, remember, and carry out simple instructions; occasional interaction with coworkers; ability to make simple work-related decisions; regular

breaks at two-hour intervals; and tolerance for occasional exposure to bright light, including direct sunlight. Id. at 43. Relying on vocational evidence, the ALJ found Plaintiff could work as a marker, router, and storage facility rental clerk and therefore was not disabled. Id. at 50. As the Appeals Council denied Plaintiff’s request for review, the ALJ’s decision is the Commissioner’s final decision. AR at 1-6. Plaintiff appealed the final decision of the Commissioner to this Court. (Dkt. # 4.)

2 20 C.F.R. § 416.920. Under 42 U.S.C. § 405(g), this Court may overturn the Commissioner’s denial of social security benefits if the ALJ’s decision rests on legal error or is not supported by substantial evidence. Smartt v. Kijakazi, 53 F.4th 489, 494 (9th Cir. 2022). Substantial evidence is defined

as “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Biestek v. Berryhill, 587 U.S. 97, 102-03 (2019) (cleaned up). In applying this standard, the Court must consider the record as a whole to determine whether it contains sufficient evidence to support the ALJ’s findings. Id. Although the Court evaluates the record as a whole, it is not permitted to reweigh the evidence or substitute its judgment for that of the ALJ. Ahearn v. Saul, 988 F.3d 1111, 1115 (9th Cir. 2021). The ALJ is tasked with evaluating testimony, resolving conflicts in the medical evidence, and addressing ambiguities in the record. Smartt, 53 F.4th at 494-95. Where the evidence can be interpreted in more than one rational way, the ALJ’s decision must be upheld. Id. Even if the ALJ erred, reversal is not warranted unless the error affected the outcome of the

disability determination. Ford v. Saul, 950 F.3d 1141, 1154 (9th Cir. 2020). The party challenging the ALJ’s decision bears the burden of demonstrating harmful error. Shinseki v. Sanders, 556 U.S. 396, 409 (2009). A. The ALJ Did Not Err in Evaluating Plaintiff’s Testimony Absent evidence of malingering, an ALJ is required to provide clear and convincing reasons for discounting a claimant’s testimony. See Laborin v. Berryhill, 867 F.3d 1151, 1155 (9th Cir. 2017). That said, the ALJ is not required to believe every allegation, nor to analyze testimony line by line. See Ahearn, 988 F.3d at 1116; Lambert v. Saul, 980 F.3d 1266, 1277 (9th Cir. 2020). The question is not whether this Court is convinced, “but instead whether the ALJ’s rationale is clear enough that it has the power to convince.” Smartt, 53 F.4th at 499. At the hearing Plaintiff testified that he has lower body injuries which prevent him from doing physical work. AR at 71. He also has migraines one or twice a week which last for

multiple days. Id. His migraines make him sensitive to sound and light, and occasionally cause partial temporary blindness, brain fog, nausea, and tinnitus. Id. His last job was unusually flexible in accommodating his migraines. Id. at 71-72. His migraines are triggered by stress, neck positioning, and lights. Id. at 72. When he has partial blindness with his migraines it lasts twenty to forty minutes. Id. After a migraine ends, he has continuing symptoms, such as being inattentive, brain fog, and slow reaction time. Id. at 73. He has pain, stiffness, and a limited range of motion in his lower body. AR at 73. His right hip will “lock up” and it becomes “severely hard for [him] to – to actually, like, walk around and move.” Id. at 74. He has “flare-ups” of physical symptoms causing an increase in his mobility issues a “couple times a week.” Id. at 75-76. He cannot stand for more than twenty

minutes and can only sit for half an hour before experiencing rigidity and stiffness issues. Id. at 75, 77. He struggles with doing laundry because he cannot stand long and can only do an activity for twenty to thirty minutes at a time even on good days. Id. at 82-83. He is only comfortable reclining or lying down. Id. at 83. He has also been diagnosed with post-traumatic stress disorder and depression. AR at 79- 80. He is triggered by people appearing sick in public, which causes an anxiety spike and for him to feel as though he needs to leave the area. Id. at 79. He takes a daily migraine medication which causes insomnia, and the medication he takes at the onset of a migraine causes drowsiness. Id. at 80-81. The ALJ discounted Plaintiff’s migraine testimony, in part, as contradicted by the objective medical record. AR at 45. Plaintiff completed a headache diary reflecting nearly constant migraine headaches,3 but attended therapy appointments during many of the noted dates and rarely complained of headaches. Id. For example, on October 17, 2024, Plaintiff attended an
