v.

COMMISSIONER SOCIAL SECURITY ADMINISTRATION,

Defendant. _____________________________________

ARMISTEAD, United States Magistrate Judge

Kaitlin J. challenges the Administrative Law Judge’s denial of Social Security benefits. She argues that the ALJ failed at step three to find plaintiff disabled as meeting or equaling Listings 11.02 and 14.09; failed to adequately evaluate lay witness testimony; failed to provide clear and convincing reasons for not finding her subjective testimony credible; and failed at step five to provide a complete hypothetical to the vocational expert. (Pl.’s Br. at 6-19.) As explained below, as required by the standard of review, the Commissioner’s decision is AFFIRMED. See 42 U.S.C. § 405(g); Ford v. Saul, 950 F.3d 1141, 1154 (9th Cir. 2020) (the district court must affirm the Commissioner’s decision if the Commissioner applied proper legal standards and the findings are supported by substantial evidence in the record). (A) Step Three – Listing 14.09. The ALJ determined that plaintiff’s physical impairments did not meet or medically equal the criteria of Listing 14.09 for inflammatory arthritis. (Tr. 140.) The ALJ explained: [T]here is no documented need for an assistive device, and there is no evidence [of] inflammation or deformity in one o[r] more major joints with involvement of two or more organs/body systems or two of the constitutional symptoms or signs (severe fatigue, fever, malaise, or involuntary weight loss). The undersigned notes that the records generally show no notable joint abnormalities on examination other than recent findings of trigger fingers on the right.

(Tr. 140.) Plaintiff does not challenge the ALJ’s finding that the record does not show a need for an assistive device (Listing 14.09(A)) but challenges the ALJ’s finding that there is no evidence of inflammation in one or more major joints and asserts that the ALJ’s own citations are consistent with meeting either Listing 14.09(B) or (D). She also contends that the record documents severe fatigue and malaise, both of which would match the requirements of Listing 14.09(B)(2). (See Pl.’s Br. at 10, citing Tr. 434, 439, 2069.) As to Listing 14.09(B), the ALJ correctly analyzed plaintiff’s medical record against the requirements of the Listings: Listing 14.09(B) first requires inflammation or deformity in one or more major joints of an upper or a lower extremity with (1) involvement of two or more organs [or] body systems with one of the organs [or] body systems involved to at least a moderate level of severity and (2) at least two of the constitutional symptoms or signs (severe fatigue, fever,

Page 2 – OPINION AND ORDER Kaitlin J. v. Comm’r Soc. Sec. Admin., 6:24-cv-02107-AR malaise, or involuntary weight loss). The record supports the ALJ’s finding that the second requirement was not met. The evidence on which plaintiff relies does not show otherwise. Although plaintiff has joint swelling and trigger fingers, and this body system is at least “moderate” in severity, plaintiff fails to show a second body system that is at least moderate in severity, which Listing 14.09(B) requires. And the regulations clarify that such involvement must be a manifestation of the immune system disorder itself. See 20 C.F.R. Pt. 404, Subpt. P, App. 1, § 14.00(D)(6). Plaintiff’s argument that her musculoskeletal, neurologic, mental, and immune systems are all affected by her rheumatoid arthritis and that each system equates to at least a moderate level of severity is

unaccompanied by medical evidence. (See Pl.’s Br. at 10.) The only other body system she points to with accompanying evidence is carpal tunnel. Yet her providers classify this impairment as “mild[,]” which fails to meet the requirements of Listing 14.09(B). (See Pl.’s Br. at 9-10, but see Tr. 1747, 1752, 1814, 2226.) Accordingly, the ALJ did not err in finding that plaintiff did not meet listing 14.09(B). As to Listing 14.09(D), plaintiff asserts that the ALJ did not consider whether she suffers a marked limitation under in either (1) activities of daily living; (2) maintaining social functioning; or (3) completing tasks in a timely manner due to deficiencies in concentration, persistence, or pace. (Pl.’s Br. at 10-11.) The plaintiff bears the burden to “present medical

findings equal in severity to all the criteria for the one most similar listed impairment.” Sullivan, 493 U.S. at 531. Here, the plaintiff must show “[r]epeated manifestations of inflammatory arthritis, with at least two constitutional symptoms or signs (severe fatigue, fever, malaise, or involuntary weight loss)” and limitation of one of (1) activities of daily living (ADLs), (2)

Page 3 – OPINION AND ORDER Kaitlin J. v. Comm’r Soc. Sec. Admin., 6:24-cv-02107-AR maintaining social functioning, or (3) completing tasks in a timely manner “due to deficiencies in concentration, persistence, and pace” at the marked level. 20 C.F.R., Part 404, Subpt. P, App. 1 § 14.09(D) (emphasis added). “Marked limitation means that the signs and symptoms of your immune system disorder interfere seriously with your ability to function. Although we do not require the use of such a scale, ‘marked’ would be the fourth point on a five-point scale consisting of no limitation, mild limitation, moderate limitation, marked limitation, and extreme limitation.” Id. at § 14.00(I)(5). Plaintiff asserts that the ALJ did not consider her mental impairments in combination with her RA, but the burden is on plaintiff present medical evidence that she meets or equals a

Listing, not the ALJ. (See Pl.’s Br. at 11.); see also Sullivan, 493 U.S. at 532. Plaintiff points only to her own hearing testimony to argue that she suffers marked limitations in her ADLs, social functioning, and completing tasks in a timely manner. (See Pl.’s Br. at 11, citing Tr. 38-60.) Looking to the decision, the ALJ made specific findings that plaintiff has mild and moderate limitations in all four areas of mental functioning. (See Tr. 140-41.) The ALJ properly evaluated plaintiff’s ability to “adapt and manage oneself[,]” citing evidence showing she was the primary caregiver for her three-year-old son, that she prepared meals daily, performed household chores (such as cleaning, doing laundry, vacuuming, and doing dishes), went places by walking, driving, or riding in a car, shopped in stores weekly, and managed her own finances. (Tr. 141, citing Tr.

335-37, 2025.) The ALJ also evaluated plaintiff’s ability to concentrate or maintain pace, concluding that she has a “moderate” limitation because on examination she “displayed some difficulty with mental calculation [or] concentration” in 2020, but displayed no issues with concentration in 2021, nor do her treatment notes indicate issues with concentration.
