JONATHAN LEVENTHAL, M.D. appears in the CMS NPPES registry as a Dermatology Physician provider holding M.D. credentials at 15 YORK ST, NEW HAVEN, CT, 06510, with a listed phone of (203) 785-4632. NPI 1629338728 was issued on 05/22/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LEVENTHAL 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 3,531 prescription claims written by this provider, covering 874 Medicare beneficiaries and totaling roughly $2.9 million in drug spend, split 15% brand-name and 85% 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 73.5637/100 for the 2023 performance year (Quality 75.8435, Cost 51.4318), compared with the national average of 83.1.

Dermatology Physician is a mid-sized specialty nationwide, with 14,610 enrolled providers across 53 states and an average of 729 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.
