NANCY SEILER, FNP appears in the CMS NPPES registry as a Occupational Health Nurse Practitioner provider holding FNP credentials at 1305 PEACH ST SUITE 301, SAN LUIS OBISPO, CA, 93401, with a listed phone of (805) 250-3380. NPI 1427448414 was issued on 01/28/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SEILER 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 records for calendar year 2023 show 3,945 prescription claims written by this provider, covering 743 Medicare beneficiaries and totaling roughly $408K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 4.5%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 86.6449/100 for the 2023 performance year (Quality 80.1318), compared with the national average of 83.1.

Occupational Health Nurse Practitioner is a narrow specialty nationwide, with 369 enrolled providers across 47 states and an average of 1,135 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.
