Sergio Bello MD

Sergio Bello MD, a self-certified small disadvantaged business operating as a for-profit Subchapter S corporation in San Francisco, provides independent medical reviews of Social Security disability claim case files as a prime contractor on BPA call orders issued by the Social Security Administration. The vendor competes full-and-open, with no set-aside designations across its federal footprint.

Sergio Bello MD operates exclusively within the Social Security Administration, holding single-award BPAs for regional medical consulting services under the Regional Medical Consultants and Advisors program. The vendor maintains two primary BPA vehicles covering Region 5 (Chicago) and Region 9 (San Francisco/Mill Valley), with a combined ceiling of $3.98 million across multiple call orders. Work involves firm-fixed-price case reviews — typically 300 to 650 independent case file evaluations per call order — supporting the SSA's disability determination process. Recent task orders include a $105,080 ceiling BPA call for Southwest Region medical consultant services awarded July 1, 2026 (extending through June 30, 2027), a $52,540 call order from January 15, 2026, and a $63,048 call order from May 2025, all under the R09 program code. The vendor has also executed a single-award Region 5 BPA with a $1.34 million ceiling awarded February 1, 2023 and expiring January 31, 2026, demonstrating multi-region capability and sustained customer confidence.

Customer concentration is absolute: the Social Security Administration accounts for 35 of 37 total awards (95% of awards, $7.8 million combined potential value) and represents the only distinct federal customer served. The vendor operates three top parent BPA vehicles — Blanket Purchase Agreement 28321321AC0940049 with 10 task orders ($722 thousand combined potential value), SS091140090 with 10 task orders ($627 thousand), and SS09164C030 with 6 task orders ($934 thousand). Activity has remained steady at one to two awards per year over 2022 through 2026, with a combined potential value of $7.9 million and obligated dollars of $2.6 million (33% obligated). The vendor faces minimal near-term recompete exposure, with only one award ($105 thousand) completing within the next twenty-four months. Primary NAICS coding reflects physician office operations — 24 awards under Offices of Physicians (except Mental Health Specialists) and 13 under Offices of Physicians, Mental Health Specialists — with PSC coding dominated by Medical consultation (27 awards) and supporting professional expertise (2 expert witness awards).
