ROSLYN MCKAY, WHNP appears in the CMS NPPES registry as a Women's Health Nurse Practitioner provider holding WHNP credentials at 201 LIBERTY DRIVE, WITTENBERG, WI, 54499, with a listed phone of (715) 253-2119. NPI 1659367688 was issued on 09/26/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MCKAY 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 1,179 prescription claims written by this provider, covering 100 Medicare beneficiaries and totaling roughly $47K in drug spend, split 9% brand-name and 91% 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 78.8552/100 for the 2023 performance year (Quality 66.6851, Cost 54.8733), compared with the national average of 83.1.

Women's Health Nurse Practitioner is a mid-sized specialty nationwide, with 9,452 enrolled providers across 55 states and an average of 262 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.
