What Is a NAICS Code?

NAICS stands for the North American Industry Classification System. It is the standard system used by U.S. federal statistical agencies to classify business establishments when collecting, analyzing, and publishing data about the economy. A NAICS code classifies an establishment according to its primary economic activity. It does not identify a specific company, customer base, service line, revenue level, or buying intent.

NAICS was introduced in 1997 to replace the Standard Industrial Classification (SIC) system. It was developed jointly by the United States, Canada, and Mexico to support comparable North American business statistics.

Healthcare NAICS Codes: Sector 62

Healthcare businesses are classified in NAICS Sector 62, Health Care and Social Assistance. The Census Bureau describes it as the sector of establishments providing health care and social assistance for individuals. The two activities share one sector because the boundary between them is not always clear, so its industries run on a continuum from medical care to social assistance.

How Healthcare NAICS Codes Are Structured

Each additional digit generally provides greater classification detail, although the hierarchy does not mean that every additional digit describes a separate physical location or service line. NAICS primarily classifies establishments according to their primary economic activity. An establishment is generally a single physical location, while one company may operate multiple establishments and may have different classifications across locations

6 digitsNational industry621111Offices of Physicians (except Mental Health Specialists)

The five-digit industry level is generally shared across Canada, Mexico, and the United States. Each country may add national detail at the six-digit level, so six-digit codes are country-specific.

FAQs

A NAICS code is a number from the North American Industry Classification System that classifies a business establishment according to its primary economic activity. Codes run from two to six digits, and each extra digit makes the classification more specific.

Healthcare falls under NAICS Sector 62, Health Care and Social Assistance. Its health care subsectors are 621 (Ambulatory Health Care Services), 622 (Hospitals) and 623 (Nursing and Residential Care Facilities), while 624 covers Social Assistance.

NAICS 621 is Ambulatory Health Care Services. It covers outpatient care such as offices of physicians, dentists and other health practitioners, outpatient care centers, medical and diagnostic laboratories, home health care services and ambulance services.

NAICS 622 is Hospitals. It covers establishments that provide medical, diagnostic and treatment services to inpatients, split into general medical and surgical hospitals (6221), psychiatric and substance abuse hospitals (6222) and specialty hospitals (6223).

NAICS 623 is Nursing and Residential Care Facilities. It covers residential care combined with nursing, supervisory or other care, including skilled nursing facilities, continuing care retirement communities and assisted living facilities for the elderly.

NAICS 624 is Social Assistance. It covers social assistance services provided directly to clients, such as individual and family services, community food and housing, vocational rehabilitation and child care services.

Physician offices are classified under 6211, Offices of Physicians. In the 2022 U.S. structure, 621111 covers Offices of Physicians (except Mental Health Specialists) and 621112 covers Offices of Physicians, Mental Health Specialists.

A NAICS code has two to six digits: 2 digits for the sector, 3 for the subsector, 4 for the industry group, 5 for the NAICS industry and 6 for the U.S. national industry.

Yes. Businesses can use NAICS codes as one input for market research and segmentation, for example to group healthcare accounts by industry. Codes work best when combined with other attributes such as location, company size and job role.

No. NAICS classifies an establishment by its primary economic activity. A code should not be treated as a complete description of every product, service, customer or business function of a company.
