This page compares two distinct NUCC-taxonomy specialties tracked by the CMS National Plan and Provider Enumeration System: Independent Duty Corpsman, which currently counts 2,980 enrolled providers across 45 U.S. states and territories, and Military Health Care Provider, with 3,080 providers across 51 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 Independent Duty Corpsman or Military Health Care Provider 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, Military Health Care Provider carries the larger provider roster (3,080 vs 2,980), and Military Health Care Provider has the wider geographic footprint at 51 states versus 45. The top Independent Duty Corpsman concentration sits in California (1,373 providers), while Military Health Care Provider peaks in California (567). 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 — Independent Duty Corpsman and Military Health Care Provider 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.
