About Ellen Rozenfeld
Ellen Rozenfeld, a woman-owned sole proprietorship based in Chicago, Illinois, provides independent medical case review and quality assurance services for disability claim adjudication to the Social Security Administration as a prime contractor under multiple Blanket Purchase Agreements, competing in open market (non-set-aside) awards.
Rozenfeld operates exclusively as a prime contractor (100% of recent awards) and holds physician credentials that anchor her work to medical consultant and expert-witness services under SSA's Medical Contractors program. The vendor has maintained a continuous relationship with SSA since 2004, delivering disability claim file reviews, independent medical evaluations, and quality assurance assessments of case review work performed by other regional medical contractors. Recent representative work includes a $257,444.80 BPA call order awarded July 1, 2026, for 2,000 independent case reviews and 480 hours of non-case review medical consulting services through June 30, 2027; a $349,204.00 call order from July 2023 for 3,000 independent case reviews and 400 non-case service hours through May 31, 2024; and a $320,463.60 call order from July 2022 for 2,800 independent case reviews and 360 hours of non-case services through July 2023.
Customer concentration is absolute: the Social Security Administration accounts for 66 of 67 awards (99% of recent awards) and $10.1 million of $10.6 million combined potential value across all federal sources. Rozenfeld sits on four parent SSA Blanket Purchase Agreements: SS10631150192 (21 task orders, $822 thousand combined potential value), SS05164C036 (15 task orders, $2 million combined potential value), SS051140086 (13 task orders, $1.4 million combined potential value), and 28321321AC0540003 (12 task orders, $2.2 million combined potential value). The underlying IDIQ BPA framework is valued at $2.391 million and runs through January 31, 2026, with individual call orders structured as firm fixed-price contracts.
Activity has remained flat in recent years—two awards each in 2023, 2025, and 2026, three in 2024—with only one award (valued at $257 thousand) scheduled for completion within the next twenty-four months. Rozenfeld's service delivery is geographically concentrated in SSA Region 5 (Chicago area), with all work grounded in NAICS 621111 (Offices of Physicians, except Mental Health Specialists) and PSC Medical code 6500, reflecting her role as a licensed independent medical consultant rather than a staffing or professional-services firm.
