MARVIN FANGMAN, M.A., IAADC appears in the CMS NPPES registry as a Addiction (Substance Use Disorder) Counselor provider holding M.A., IAADC credentials at 501 NORTH SHERMAN, PRAIRIE CITY, IA, 50228, with a listed phone of (515) 994-3562. NPI 1245613108 was issued on 07/09/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FANGMAN 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 Addiction (Substance Use Disorder) Counselor providers operate outside Part D entirely.

Addiction (Substance Use Disorder) Counselor is a high-volume specialty nationwide, with 109,141 enrolled providers across 55 states and an average of 645 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.
