GERARDO ALVARADO, RDN appears in the CMS NPPES registry as a Gerontological Nutrition Registered Dietitian provider holding RDN credentials at 1900 E SLAUSON AVE STE B, HUNTINGTON PARK, CA, 90255, with a listed phone of (323) 277-7678. NPI 1194603761 was issued on 08/22/2025. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALVARADO 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 Gerontological Nutrition Registered Dietitian providers operate outside Part D entirely.

Gerontological Nutrition Registered Dietitian is a narrow specialty nationwide, with 86 enrolled providers across 28 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.
