NAICS 621420 – Outpatient Mental Health and Substance Abuse Centers encompasses the provision of ambulatory behavioral health services, including individual and group psychotherapy, crisis intervention, substance use disorder counseling, psychiatric evaluation, and co-occurring disorder treatment delivered in non-residential settings. These services are critical to federal health and human service missions, supporting veterans, active-duty personnel, federal employees, and beneficiaries of the Indian Health Service and Medicaid programs. The sector operates within a complex regulatory framework governed by SAMHSA guidelines, HIPAA compliance, and accreditation standards such as CARF or JCAHO. Contractors in this space must demonstrate clinical expertise, workforce credentialing, and interoperability with electronic health record systems to meet federal contracting requirements. No contractor data is available to identify leading primes or small businesses operating in this sector. However, typical participants include community mental health centers, nonprofit behavioral health networks, and specialized clinical service providers with experience in federal grant-funded programs. No agency data is available to specify primary buyers. Nonetheless, demand is likely driven by the Department of Veterans Affairs, the Substance Abuse and Mental Health Services Administration, the Department of Health and Human Services, and the Department of Defense through its Military Health System and TRICARE network, all of which prioritize accessible, evidence-based outpatient behavioral health care. The competitive landscape is characterized by high regulatory barriers and a reliance on skilled clinical staff, creating opportunities for specialized providers with proven track records in federal compliance and telehealth delivery. Growing emphasis on integrated care models and workforce expansion in underserved areas suggests increasing procurement activity in rural and veteran-focused regions.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 621420 work as a small business.

$19.0M
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.
