Medicare Part D records for calendar year 2023 show 128 prescription claims written by this provider, covering 40 Medicare beneficiaries and totaling roughly $3K in drug spend. 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 80.2995/100 for the 2023 performance year (Quality 85.8155, Cost 49.3494), compared with the national average of 83.1.

Sports Medicine (Physical Medicine & Rehabilitation) Physician is a narrow specialty nationwide, with 1,267 enrolled providers across 52 states and an average of 579 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.
