PATRICIA PIENAAR, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 3533 SOUTHERN BLVD STE 3750, KETTERING, OH, 45429, with a listed phone of (937) 610-3220. NPI 1235651092 was issued on 07/13/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PIENAAR 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 1,142 prescription claims written by this provider, covering 209 Medicare beneficiaries and totaling roughly $894K in drug spend, split 62% brand-name and 38% 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 78.9373/100 for the 2023 performance year (Quality 69.8099, Cost 59.9811), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 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.
