REGAN CHALLINOR, M.S., CGC appears in the CMS NPPES registry as a Genetic Counselor (M.S.) provider holding M.S., CGC credentials at DUKE UNIVERSITY MEDICAL CENTER DIVISION OF MFM, DURHAM, NC, 27710, with a listed phone of (919) 684-3604. NPI 1962436899 was issued on 07/10/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHALLINOR 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 Genetic Counselor (M.S.) providers operate outside Part D entirely.

Genetic Counselor (M.S.) is a mid-sized specialty nationwide, with 6,310 enrolled providers across 52 states and an average of 134 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.
