WILLIAM BUTLER, MD, MTM&H, FACS appears in the CMS NPPES registry as a Undersea and Hyperbaric Medicine (Preventive Medicine) Physician provider holding MD, MTM&H, FACS credentials at 732 OKUMA DR, CHESTER, VA, 23836, with a listed phone of (804) 909-1803. NPI 1407940729 was issued on 10/03/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BUTLER 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Undersea and Hyperbaric Medicine (Preventive Medicine) Physician providers operate outside Part D entirely.

Undersea and Hyperbaric Medicine (Preventive Medicine) Physician is a narrow specialty nationwide, with 237 enrolled providers across 41 states and an average of 522 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.
