AARON JACOBS, PHD appears in the CMS NPPES registry as a Chemistry Pathology Specialist/Technologist provider holding PHD credentials at 201 CENTER ST W, ROCHESTER, MN, 55902, with a listed phone of (507) 284-2511. NPI 1083567408 was issued on 02/16/2026. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JACOBS 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 Chemistry Pathology Specialist/Technologist providers operate outside Part D entirely.

Chemistry Pathology Specialist/Technologist is a narrow specialty nationwide, with 41 enrolled providers across 15 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.
