This page compares two distinct NUCC-taxonomy specialties tracked by the CMS National Plan and Provider Enumeration System: Hospice and Palliative Medicine (Obstetrics & Gynecology) Physician, which currently counts 90 enrolled providers across 29 U.S. states and territories, and Obstetrics & Gynecology Physician, with 44,326 providers across 56 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 Hospice and Palliative Medicine (Obstetrics & Gynecology) Physician or Obstetrics & Gynecology Physician 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, Obstetrics & Gynecology Physician carries the larger provider roster (44,326 vs 90), and Obstetrics & Gynecology Physician has the wider geographic footprint at 56 states versus 29. The top Hospice and Palliative Medicine (Obstetrics & Gynecology) Physician concentration sits in California (17 providers), while Obstetrics & Gynecology Physician peaks in California (4,943). 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 — Hospice and Palliative Medicine (Obstetrics & Gynecology) Physician and Obstetrics & Gynecology Physician 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.
