Opinion

NICOLE MASTROMATTEO, No. 2:25-cv-00267-CKD Plaintiff, v. ORDER SECURITY, Defendant.

Plaintiff seeks judicial review of a final decision of the Commissioner of Social Security (“Commissioner”) denying applications for Disability Income Benefits (“DIB”) and Supplemental Security Income (“SSI”) under Titles II and XVI of the Social Security Act (“Act”), respectively. The parties have consented to magistrate judge jurisdiction. For the reasons discussed below, the court will deny plaintiff’s motion for summary judgment and grant the Commissioner’s cross-motion for summary judgment. Plaintiff, born in 1973, applied for DIB and SSI in 2022, alleging disability beginning September 1, 2020. Administrative Transcript (“AT”) 17, 29. The alleged onset date was later amended to February 13, 2021. AT 19. Plaintiff stated that she was unable to work due to degenerative disc disease in upper back, bursitis in left shoulder, severe lower back pain, and seizures. AT 79. On April 17, 2024, an Administrative Law Judge (ALJ) issued a decision finding plaintiff not disabled between February 13, 2021, and the date of the decision. AT 17-30. The ALJ made the following findings (citations to 20 C.F.R. omitted): 1. The claimant meets the insured status requirements of the Social Security Act through September 30, 2022. 2. The claimant has not engaged in substantial gainful activity since February 13, 2021, the amended alleged onset date. 3. The claimant has the following severe impairments: seizure disorder, post-traumatic stress disorder (PTSD), and history of alcohol use disorder with mild neurocognitive deficits. 4. The claimant does not have an impairment or combination of impairments that meets or medically equals the severity of one of the listed impairments in 20 CFR Part 404, Subpart P, Appendix 1. 5. After careful consideration of the entire record, the claimant has had the residual functional capacity to perform light work except that she can occasionally perform postural activities but never climb ladders, ropes, or scaffolds; she cannot work around unprotected heights and must be afforded other seizure precautions; she is limited to simple tasks in a routine environment; she can occasionally interact with coworkers but never interact with the public; and she is precluded from fast-paced work such as rapid assembly or conveyor belt work. 6. The claimant is unable to perform past relevant work. 7. The claimant was born [in 1973] and was 46 years old, which is defined as a younger individual age 18-49, on the alleged disability onset date. The claimant subsequently changed age category to closely approaching advancing age. 8. The claimant has at least a high-school education. 9. Transferability of job skills is not material to the determination of disability because using the Medical-Vocational Rules as a framework supports a finding that the claimant is ‘not disabled,’ whether or not the claimant has transferable job skills. 10. Considering the claimant’s age, education, work experience, and residual functional capacity, there are jobs that exist in significant numbers in the national economy that the claimant can perform. 11. The claimant has not been under a disability, as defined in the Social Security Act, from February 13, 2021, through the date of this decision.

AT 19-30.
