JUSTINA TAM, M.D. appears in the CMS NPPES registry as a Urogynecology and Reconstructive Pelvic Surgery (Urology) Physician provider holding M.D. credentials at STONY BROOK UROLOGY, STONY BROOK, NY, 11794, with a listed phone of (631) 444-6270. NPI 1073932521 was issued on 04/14/2014.

Medicare Part D records for calendar year 2023 show 517 prescription claims written by this provider, covering 180 Medicare beneficiaries and totaling roughly $104K in drug spend, split 30% brand-name and 70% 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 98.5241/100 for the 2023 performance year (Quality 82.8545), compared with the national average of 83.1.

Urogynecology and Reconstructive Pelvic Surgery (Urology) Physician is a narrow specialty nationwide, with 109 enrolled providers across 28 states and an average of 1,103 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.
