This page compares two distinct NUCC-taxonomy specialties tracked by the CMS National Plan and Provider Enumeration System: Radiography Radiologic Technologist, which currently counts 452 enrolled providers across 51 U.S. states and territories, and Radiologic Technologist, with 908 providers across 52 states. Each clinician on these rosters selected a primary NUCC code at NPI enrollment, so the totals measure how many providers self-identify their primary practice as Radiography Radiologic Technologist or Radiologic Technologist rather than the total population ever trained or credentialed in either field — dual-certified clinicians show up under whichever code they registered first.

On national volume, Radiologic Technologist carries the larger provider roster (908 vs 452), and Radiologic Technologist has the wider geographic footprint at 52 states versus 51. The top Radiography Radiologic Technologist concentration sits in California (73 providers), while Radiologic Technologist peaks in California (110). The per-capita columns in the table below normalize each state's raw count against 2023 Census population estimates, which matters because absolute provider counts track population scale first and specialty density second — a small state with a strong training pipeline can out-rank a larger state on per-100K availability.

Use this comparison to understand relative availability, not to judge clinical substitutability — Radiography Radiologic Technologist and Radiologic Technologist are distinct specialties with different scopes of practice, training requirements, and conditions they treat, even when their NUCC categories overlap. Important: PlainDoctor is a directory of publicly available CMS government data, not medical advice, a provider rating, or a recommendation about which specialty a patient should consult. Always work with a licensed clinician to determine which specialty is appropriate for your condition, verify any specific provider through the NPPES NPI Registry and the relevant state medical board, and consult the NUCC taxonomy documentation for the formal scope-of-practice definitions behind each specialty code.
