NAICS Codes: Choosing Between Health and Admin Services
Why NAICS Code Selection Matters
For small business contractors venturing into the world of government contracts, choosing the correct NAICS (North American Industry Classification System) code is one of the most consequential decisions you can make. Your NAICS code not only defines your business in the eyes of the government but also determines your eligibility for specific contracts, set-asides, and size standards. Selecting the wrong code can make you invisible to contracting officers who are actively searching for businesses like yours.
Understanding NAICS 621 vs. NAICS 561
A common point of confusion for many businesses is distinguishing between NAICS 621 (Ambulatory Health Care Services) and NAICS 561 (Office Administrative Services). Both codes serve distinct industry sectors, and understanding the difference is crucial.
NAICS 621: Ambulatory Health Care Services
This code is designated for businesses that provide health care services directly to patients without the need for overnight hospital stays. This includes:
- Physicians' offices
- Dentists
- Outpatient care centers
- Medical and diagnostic laboratories
If your business involves direct patient care or medical diagnostics, NAICS 621 is likely the appropriate classification.
NAICS 561: Office Administrative Services
On the other hand, NAICS 561 covers businesses that provide support services to other organizations. These services include:
- Office administration
- Facilities support services
- Employment services
- Business support services
If your business focuses on providing administrative, clerical, or support services to other companies, NAICS 561 is more fitting.

The Impact of Choosing the Right NAICS Code
Selecting the correct NAICS code has several downstream impacts on your business:
- Set-Aside Eligibility: Many government contracts are set aside for small businesses within specific NAICS codes. Using the correct code ensures you are eligible for these opportunities.
- Size Standards: NAICS codes are linked to size standards that determine whether your business qualifies as a small business. Choosing the wrong code can inadvertently disqualify you from small business status.
- Contract Visibility: Contracting officers use NAICS codes to find businesses that match their contract needs. An incorrect code can render your business invisible to these officers, reducing your chances of being considered for contracts.
