Analysis
NAICS 621512 is the 2022 national industry for diagnostic imaging centers, part of 62151 (Medical and Diagnostic Laboratories). Census lists 22 example activities under it in the official index.
County Business Patterns counts 6,968 US establishments in this code in 2023, employing 99,727 people at an average annual payroll of $74,933 per employee (62nd percentile of national industries). 48% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 2nd of the 2 codes at this level within Medical and Diagnostic Laboratories, with 29.5% of them.
Between 2018 and 2023 the number of establishments grew 12% and employment rose 9%. 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.
Its index entries, the activities Census uses to assign businesses to this code, include CAT (computerized axial tomography) scanner centers, computer tomography (CT-SCAN) centers, CT-SCAN (computer tomography) centers and dental X-ray laboratories, among 22 in all.
