NAICS 621111 – Offices of Physicians (except Mental Health Specialists) encompasses the provision of outpatient medical services by licensed physicians practicing in private or government-contracted clinical settings, excluding mental health specialists. This sector includes primary care, internal medicine, pediatrics, obstetrics and gynecology, and other non-psychiatric specialty practices delivering diagnostic, preventive, and treatment services under federal healthcare programs. In government contracting, this NAICS code supports mission-critical health delivery systems for military personnel, veterans, and federal employees, often through managed care arrangements, telehealth platforms, and on-site clinic operations. It bridges clinical care delivery with federal health infrastructure, requiring compliance with HIPAA, Medicare billing protocols, and DoD/VHA clinical standards. Top contractors in this space include DAX SAFETY & STAFFING SOLUTIONS, LLC, NEW WAVE PEOPLE, INC, A-Z Medical Services, PLLC, and RADSURITY, PA, representing a mix of small businesses and specialized medical staffing firms that provide physician services, practice management, and clinical support under government contracts. These entities typically operate as subcontractors to larger health systems or as direct vendors to federal health agencies, emphasizing credentialing, on-demand staffing, and regulatory compliance. The Department of Veterans Affairs, Department of Health and Human Services, Department of Defense, Washington Headquarters Services, and the Department of Justice are the primary federal buyers, driving demand through VA healthcare networks, CDC health initiatives, military medical readiness programs, and federal employee wellness services. These agencies rely on this NAICS code to sustain accessible, compliant outpatient care for beneficiaries across domestic and overseas installations. The competitive landscape is characterized by high regulatory barriers and a preference for firms with prior federal healthcare experience, particularly those holding small business certifications and possessing established provider networks. Opportunities are concentrated in regions with high veteran populations and military bases, with growing demand for integrated, value-based care models and remote clinical support services.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 621111 work as a small business.

$16.0M
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
