Yancey Disability, Inc. in Carlsbad's La Costa area represents claimants seeking Social Security Disability benefits before Administrative Law Judges under Title II and SSI of the Social Security Act. Building medical evidence files for hearing preparation frequently involves obtaining diagnostic imaging from SimonMed Imaging - Carlsbad to document the severity of musculoskeletal, neurological, and autoimmune impairments. The firm was established in 2017 with dual licensure in California and Georgia, authorizing nationwide representation before the Social Security Administration. Case strategy targets the five-step sequential evaluation process outlined in 20 CFR § 404.1520, with residual functional capacity arguments tailored to each claimant's specific exertional and non-exertional limitations. Treating-physician opinion letters from orthopedic and neurological specialists — including Orthopaedic Specialists of North County — are compiled into the evidentiary record to establish whether impairments meet or equal the SSA's Listing of Impairments. The most complex representations involve federal district court appeals under 42 U.S.C. § 405(g), requiring persuasive briefing on whether the ALJ's residual functional capacity finding was supported by substantial evidence in the administrative record.
