William C Oppenheim specializes in providing independent medical consultant services to support federal disability adjudication programs, with a focused expertise in reviewing disability claim case files for the Social Security Administration. The contractor delivers objective medical evaluations of clinical documentation to determine eligibility for Social Security Disability Insurance and Supplemental Security Income programs, applying authoritative knowledge of diagnostic criteria, functional limitations, and SSA’s Listing of Impairments. Core capabilities include case file analysis, medical opinion formulation, adherence to SSA’s sequential evaluation process, and compliance with federal adjudicative standards—ensuring accurate, defensible, and timely disability determinations. The contractor’s technical proficiency lies in interpreting complex medical records, applying evidence-based clinical reasoning, and maintaining strict confidentiality and procedural integrity under federal oversight. The contractor maintains a consistent, long-standing relationship with the Social Security Administration, delivering regional medical consultant services across multiple geographic regions, including Region 8 and the Mid-West/West region centered in Denver. Work is performed under blanket purchase agreements that enable scalable, on-demand medical review support for high-volume disability claim backlogs, ensuring operational continuity and adherence to SSA’s quality assurance protocols. The primary industry focus is on NAICS 621111, which encompasses physician offices providing non-mental health clinical services—here applied in a federal administrative context rather than direct patient care. This positions the contractor uniquely within the government contracting space as a medical expert serving administrative adjudication systems, bridging clinical medicine with federal program integrity. Operating as a sole proprietorship (Entity Structure 2J), the contractor is based in Morristown, New Jersey, and serves federal clients without formal certifications. Their market positioning is defined by niche expertise in SSA disability reviews, leveraging deep clinical knowledge to support mission-critical decision-making within the federal benefits system.
