NAICS 622310 – Specialty (except Psychiatric and Substance Abuse) Hospitals covers the operation of inpatient healthcare facilities dedicated to specialized medical services such as cardiovascular care, oncology, orthopedics, neonatology, rehabilitation, and other non-psychiatric therapeutic disciplines. These institutions provide acute and subacute care under licensed medical supervision, often integrating advanced diagnostic technologies, surgical suites, and multidisciplinary clinical teams. In the federal contracting landscape, this NAICS code is critical to supporting the Department of Veterans Affairs’ mission to deliver high-acuity, specialty-driven care to veteran populations through a network of VA medical centers and contracted tertiary care providers. The sector requires strict compliance with Medicare conditions of participation, HIPAA, and federal healthcare accreditation standards, making it a highly regulated and operationally complex segment of the broader health services procurement ecosystem. The leading contractor in this space is MARATHON MEDICAL CORPORATION, a large prime contractor with deep expertise in managing specialized hospital operations under federal agreements. Its presence reflects a competitive landscape dominated by experienced healthcare system operators with proven capabilities in federal compliance, clinical quality metrics, and VA-specific care protocols. Small businesses and minority-owned firms are increasingly participating as subcontractors in ancillary services such as staffing, logistics, and IT integration. The Department of Veterans Affairs is the primary federal buyer, driving demand through its nationwide network of specialty care programs aimed at addressing veteran-specific health conditions, including trauma recovery, chronic disease management, and post-surgical rehabilitation. Contracting is primarily executed through long-term service agreements, managed care contracts, and facility operation partnerships. The market is characterized by high barriers to entry due to regulatory complexity and infrastructure requirements, but offers sustained opportunity for contractors with proven experience in federal healthcare delivery, clinical outcomes reporting, and VA interoperability standards. Demand remains steady, anchored in veteran population needs and ongoing modernization of VA healthcare infrastructure.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 622310 work as a small business.

$47.0M
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.
