NANCY GUSTAFSON LUTHI, MS, RD, CDE, CSOWM appears in the CMS NPPES registry as a Obesity and Weight Management Nutrition Registered Dietitian provider holding MS, RD, CDE, CSOWM credentials at 2101 ELM ST N, FARGO, ND, 58102, with a listed phone of (701) 239-3700. NPI 1144525627 was issued on 01/14/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GUSTAFSON LUTHI 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 Obesity and Weight Management Nutrition Registered Dietitian providers operate outside Part D entirely.

Obesity and Weight Management Nutrition Registered Dietitian is a narrow specialty nationwide, with 382 enrolled providers across 46 states, 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.
