MARK GERSMAN, M.D. appears in the CMS NPPES registry as a Retina Specialist (Ophthalmology) Physician provider holding M.D. credentials at 4676 DOUGLAS CIR NW, CANTON, OH, 44718, with a listed phone of (330) 494-1116. NPI 1205839552 was issued on 05/31/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GERSMAN 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 562 prescription claims written by this provider, covering 193 Medicare beneficiaries and totaling roughly $26K in drug spend, split 52% brand-name and 48% 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 98.8/100 for the 2023 performance year (Quality 100), compared with the national average of 83.1.

Retina Specialist (Ophthalmology) Physician is a narrow specialty nationwide, with 913 enrolled providers across 48 states and an average of 558 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.
