Analysis
NAICS 6223 is the 2022 industry group for specialty (except psychiatric and substance abuse) hospitals, part of 622 (Hospitals).
It has only one more detailed code, 622310, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 29% and employment rose 23%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
County Business Patterns counts 995 US establishments in this code in 2023, employing 296,115 people at an average annual payroll of $78,890 per employee (67th percentile of national industries). 7% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 2nd of the 3 codes at this level within Hospitals, with 13.2% of them.
