JOHN MCCULLUM, DDS, MPH appears in the CMS NPPES registry as a Oral & Maxillofacial Surgery (D.M.D.) provider holding DDS, MPH credentials at 12210 PECAN ST, AUSTIN, TX, 78727, with a listed phone of (512) 258-1636. NPI 1912496613 was issued on 05/08/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MCCULLUM most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 49 prescription claims written by this provider, covering 27 Medicare beneficiaries and totaling roughly $338 in drug spend, with an opioid prescribing rate of 22.4%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Oral & Maxillofacial Surgery (D.M.D.) is a narrow specialty nationwide, with 1,112 enrolled providers across 52 states and an average of 324 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
