REBECCA WALKER, RN, BSN, FNP appears in the CMS NPPES registry as a Occupational Health Registered Nurse provider holding RN, BSN, FNP credentials at 814 PIERCE ST STE 300, SIOUX CITY, IA, 51101, with a listed phone of (712) 226-2600. NPI 1336797018 was issued on 08/27/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WALKER 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 1,875 prescription claims written by this provider, covering 461 Medicare beneficiaries and totaling roughly $102K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 3.5%. 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.

Occupational Health Registered Nurse is a narrow specialty nationwide, with 342 enrolled providers across 46 states and an average of 620 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.
