SANDRA KARP, NMNP appears in the CMS NPPES registry as a Obstetrics & Gynecology Nurse Practitioner provider holding NMNP credentials at 9555 SW BARNES RD, PORTLAND, OR, 97225, with a listed phone of (503) 292-3577. NPI 1679821672 was issued on 08/22/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KARP 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 202 prescription claims written by this provider, covering 14 Medicare beneficiaries and totaling roughly $40K in drug spend, split 13% brand-name and 87% generic by claim count. 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.

Obstetrics & Gynecology Nurse Practitioner is a narrow specialty nationwide, with 2,864 enrolled providers across 52 states and an average of 232 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.
