SAI R Nimmagadda

SAI R Nimmagadda, a sole proprietorship based in Long Grove, Illinois, delivers medical consulting and disability-claims review services to the Social Security Administration as a prime contractor on a non-set-aside basis, operating entirely within a single-customer framework with no subcontract activity.

Nimmagadda is registered under NAICS 621111 (Offices of Physicians, except Mental Health Specialists) and 621112 (Offices of Physicians, Mental Health Specialists), with PSC coding concentrated in Medical-Medical/Psychiatric Consultation and Professional Expert Witness support. The vendor operates as a sole proprietorship and competes in full-and-open procurements; no SBA set-asides appear in the award footprint. The business is fundamentally a solo medical practitioner model — the source refers to "Dr. SAI R Nimmagadda" — providing independent case reviews, medical consulting hours, and quality assurance reviews of disability claim case files in the Social Security Administration's Region 5 (Chicago) and other regional offices.

Customer concentration is absolute. The Social Security Administration accounts for 62 of 63 awards (98% of recent volume) and $8.5 million of $9.1 million in combined potential value. All recent work flows through four parent BPAs, with the largest vehicle (Blanket Purchase Agreement 28321321AC0540002) anchoring 14 task orders valued at $2.6 million, followed by Blanket Purchase Agreement SS05164C020 at 15 task orders worth $1.5 million. The master BPA established in February 2021 carries a ceiling of $2,391,742.50 and has generated sustained call orders through 2026; recent representative call orders include a $299,970 award in July 2026 for case file reviews and medical consulting services, a $350,797.25 order in July 2024 for regional medical advisor services covering 3,100 independent case reviews, and a $301,539.60 order in July 2022 for 2,610 independent case reviews and 360 hours of non-case services. Work is performed in Long Grove, Illinois and Baltimore, Maryland, with performance periods typically running twelve months or less.

Activity has remained modest and flat — two to three awards per year over the past five years — with only two awards (combined potential value $355 thousand) completing within the next twenty-four months. The vendor holds no federal IDVs and operates no teaming relationships; all work is direct SSA engagement on a sole-proprietor basis.
