NAICS code for a hospital: 622110, 622210 or 622310, and the SIC codes

This page is for hospital finance, compliance and procurement staff filling in a NAICS or SIC field, for vendors classifying hospital customers, and for sellers building hospital lists.

The NAICS codes for hospitals

All three sit in Subsector 622, Hospitals. Each Census definition starts with establishments "known and licensed as" that type of hospital, which maintain inpatient beds, feed their patients and have an organized medical staff.

How to choose, and what isn't a hospital

The cross-references send "hospitals" that aren't licensed or run as hospitals elsewhere:

A hospital's outpatient clinics, labs, imaging and pharmacy stay in its code when they're part of the hospital establishment. A health system's headquarters that manages its hospitals is 551114 (corporate, subsidiary and regional managing offices), and a separately located physician practice it owns is 621111.

The SIC codes for hospitals

8062 and 8063 map one to one. 8069 doesn't, because the SIC manual put children's hospitals and alcohol and drug rehabilitation hospitals in the specialty code, while NAICS moves them to the general and psychiatric codes. On SEC EDGAR, hospital operators file under 8062 or the group code 8060 (Services-Hospitals).

How many hospitals there are

County Business Patterns normally leaves out government, but its methodology makes an exception for hospitals: government-sponsored hospitals are included. The 2023 figures, on a 2017 NAICS basis (these codes didn't change in 2022):

General hospitals are big establishments: 1,695 of the 5,777 have 1,000 or more employees, 899 have 500 to 999 and 943 have 250 to 499. But 839 have fewer than 50 employees and 555 fewer than five, so filter by size before treating every establishment in the code as a full hospital. The states with the most general hospital establishments are California (600), Texas (491), Florida (300), Pennsylvania (225) and New York (210). Specialty hospitals are concentrated in Texas (151) and Louisiana (71).

Other counts differ because they count licensed or certified hospitals rather than payroll establishments; the list of hospitals compares them.

SBA size standards

All three hospital codes have a size standard of $47.0 million in average annual receipts in the SBA's table effective March 17, 2023, so only the smallest independent and rural hospitals count as small. Related codes: 621493 freestanding surgery and emergency centers $19.0 million, 623110 nursing facilities $34.0 million.

Where the code gets used

• Vendor and data records. Suppliers and data providers classify customers by code. Record each facility under its own code, so a filter on 622110 doesn't drop a system's rehabilitation or behavioral hospitals.
• Federal contracts. Agencies buying hospital services under a solicitation use one code, and its size standard applies.
• Tax returns. The IRS Schedule C list groups all three as 622000, Hospitals, a tax code rather than a NAICS code.

Finding hospital companies

Investor-owned hospital operators file with the SEC under SIC 8062 (EDGAR list for SIC 8062) or 8060. The largest by revenue in their latest 10-K:

HCA's own facilities show why one company needs several codes: its general acute care hospitals are 622110, its behavioral hospitals 622210, its rehabilitation hospitals 622310 and its surgery centers 621493. Nonprofit and government hospitals have no listed shares and don't file 10-Ks; for those, use the code with a size filter, and see selling to hospitals for how they buy. Bebop finds hospitals and health systems from a plain-language description and researches each account.

Worked example

Illustrative example. The organization and figures are invented to show the method.

Valley Ridge Health (valleyridge.example) is a nonprofit system with a 320-bed general hospital, a 40-bed inpatient rehabilitation hospital on a separate campus, two freestanding emergency departments and a home office.

1. The general hospital: 622110.
2. The rehabilitation hospital: 622310, because it's separately licensed as a rehabilitation hospital.
3. The freestanding emergency departments: 621493.
4. The home office: 551114.
5. SIC codes on a supplier's form: 8062 for the system; 8069 for the rehabilitation hospital.

A vendor selling to Valley Ridge should record each facility under its own code, since a list filtered on 622110 alone misses the rehabilitation hospital and the ERs.
