MARK WEINSTEIN, M.D. appears in the CMS NPPES registry as a Pediatrics Physician provider holding M.D. credentials at 5 FRANKLIN AVE STE 102, BELLEVILLE, NJ, 07109, with a listed phone of (973) 759-5842. NPI 1528274040 was issued on 05/14/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WEINSTEIN 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 1,008 prescription claims written by this provider, covering 154 Medicare beneficiaries and totaling roughly $749K in drug spend, split 37% brand-name and 63% 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 84.0144/100 for the 2023 performance year (Quality 68.6752, Cost 76.4864), compared with the national average of 83.1.

Pediatrics Physician is a high-volume specialty nationwide, with 80,574 enrolled providers across 56 states and an average of 762 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
