JOHN HALL, DDS appears in the CMS NPPES registry as a Public Health Dentistry provider holding DDS credentials at 3359 HARTLEY DRIVE, ADRIAN, MI, 49221, with a listed phone of (517) 862-1590. NPI 1720187750 was issued on 09/22/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HALL 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 64 prescription claims written by this provider, covering 32 Medicare beneficiaries and totaling roughly $247 in drug spend, with an opioid prescribing rate of 28.1%. 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.

Public Health Dentistry is a narrow specialty nationwide, with 1,104 enrolled providers across 54 states and an average of 84 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
