Opinion

UNITED STATES DISTRICT COURT AT SEATTLE HEATHER M. K., Plaintiff, CASE NO. C25-5799-BAT v. ORDER REVERSING AND COMMISSIONER OF SOCIAL SECURITY, ADMINISTRATIVE PROCEEDINGS Defendant.

Plaintiff seeks review of the denial of her application for Supplemental Security Income. She contends the ALJ misevaluated the medical evidence, her symptom testimony, and the lay witness testimony. Dkt. 14 at 2. For the reasons below, the Court REVERSES the Commissioner’s final decision and REMANDS the matter for further administrative proceedings under sentence four of 42 U.S.C. § 405(g). Plaintiff is currently 46 years old, has a GED, and has worked as a tube filling machine operator and order clerk. Tr. 34. She applied for benefits on March 16, 2020, alleging disability as of the same date. Tr. 17. Her applications were denied initially and upon reconsideration. Tr. 106, 145. ALJ Joyce Frost-Wolf held a hearing on April 27, 2023, and issued a decision finding Plaintiff not disabled. Tr. 149-61. Plaintiff requested Appeals Council review and on November 30, 2023, the Appeals Council vacated the hearing decision and remanded the case for further proceedings. Tr. 169-70. ALJ Mark Triplett held a second hearing on October 9, 2024, and issued a decision finding Plaintiff not disabled. Tr. 17-35. As the Appeals Council denied Plaintiff’s request for review of ALJ Triplett’s decision, the ALJ’s decision is the

Commissioner’s final decision. Tr. 1-3. Utilizing the five-step disability evaluation process,1 the ALJ found:

Step one: Plaintiff has not engaged in substantial gainful activity since March 16, 2020.

Step two: Plaintiff has the following severe impairments: Right shoulder tendonitis with impingement syndrome; depressive disorder; anxiety disorder; attention deficit hyperactivity disorder (“ADHD”); and posttraumatic stress disorder (“PTSD”).

Step three: These impairments do not meet or equal the requirements of a listed impairment.2 Residual Functional Capacity: Plaintiff can perform light work as defined in 20 C.F.R. 416.967(b) except she can occasionally push/pull with the right upper extremity. She can frequently climb ramps and stairs but never climb ladders, ropes, or scaffolds. She can frequently balance, stoop, kneel, and crouch, but occasionally crawl. She can frequently, but not constantly, reach with the right, non-dominant upper extremity. She can perform simple, routine tasks, and can tolerate occasional, superficial contact with coworkers, but no direct interactive contact with the general public. She can tolerate occasional contact with supervisors. She requires regular work breaks at 2-hour intervals.

Step four: Plaintiff cannot perform her past work.

Step five: As there are jobs that exist in significant numbers in the national economy that Plaintiff can perform, she is not disabled. Tr. 20-23, 34.

1 20 C.F.R. § 416.920. 2 20 C.F.R. Part 404, Subpart P. Appendix 1. The Court will reverse the ALJ’s decision only if it is not supported by substantial evidence in the record as a whole or if the ALJ applied the wrong legal standard. Molina v. Astrue, 674 F.3d 1104, 1110 (9th Cir. 2012). The ALJ’s decision may not be reversed on account

of an error that is harmless. Id. at 1111. The Court may neither reweigh evidence nor substitute its judgment for that of the Commissioner. Thomas v. Barnhart, 278 F.3d 947, 954 (9th Cir. 2002). Where the evidence is susceptible to more than one rational interpretation, the Court must uphold the Commissioner’s interpretation. Id. Plaintiff contends the ALJ failed to properly evaluate the medical evidence, her symptom testimony, and the lay witness testimony, resulting in a deficient RFC and erroneous step five findings. Dkt. 14 at 2. A. Medical Opinion Evidence Plaintiff contends the ALJ misevaluated the opinions of Nickolas Jones, Ph.D., Terilee Wingate, Ph.D., Margie Williams, PMHNP-BC, Richard Henegan, M.D., Dorothy Leong, M.D.,

and the state agency psychological consultants. Dkt. 14 at 3-10. The ALJ considers the persuasiveness of medical opinions using five factors, but supportability and consistency are the most important factors. 20 C.F.R. § 416.920c(b)(2), (c). The ALJ must explain how he considered supportability and consistency but need not explain how he considered other factors. 20 C.F.R. § 416.920c(b). An ALJ cannot reject a doctor’s opinion as unsupported or inconsistent without providing an explanation supported by substantial evidence. Woods v. Kijakazi, 32 F.4th 785, 792 (9th Cir. 2022). Conclusions alone are insufficient – “an ALJ can satisfy the “substantial evidence” requirement by “setting out a detailed and thorough summary of the facts and conflicting evidence, stating his interpretation thereof, and making findings.”” Garrison v. Colvin, 759 F.3d 995, 1012 (9th Cir. 2014) (quoting Reddick v. Chater, 157 F.3d 715, 725 (9th Cir. 1998)). 1. Nickolas Jones, Ph.D. Dr. Jones evaluated Plaintiff on July 2, 2020, and found Plaintiff can engage in and

sustain basic activities for appropriate lengths of time, but her pace was variable, and she did not persist in difficult activities as appropriate. Tr. 676. Dr. Jones opined Plaintiff would struggle to get along with employers, coworkers, and customers in a work environment due to a high level of psychological distress and would likely experience a high level of absenteeism. Id. The ALJ found Dr. Jones’s opinion somewhat persuasive, agreeing Plaintiff’s interactions and pace were moderately affected by her mental symptoms, but found no evidence to support Dr. Jones’s opinion on excessive absenteeism. Tr. 31. The ALJ further noted Dr. Jones’s opinion was unsupported because he did not review the longitudinal record and his opinion was vague, poorly explained, and unsupported by his findings on exam. Id. As for consistency, the ALJ found the opinion inconsistent with Plaintiff’s limited participation in treatment, improvement in her
