MARK REYNOLDS, M.D. appears in the CMS NPPES registry as a Ophthalmology Physician provider holding M.D. credentials at 5409 AVENUE O, FORT MADISON, IA, 52627, with a listed phone of (319) 372-9292. NPI 1497793632 was issued on 06/02/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what REYNOLDS 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 1,824 prescription claims written by this provider, covering 351 Medicare beneficiaries and totaling roughly $204K in drug spend, split 35% brand-name and 65% 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 76.134/100 for the 2023 performance year (Quality 90.2987, Cost 30.148), compared with the national average of 83.1.

Ophthalmology Physician is a mid-sized specialty nationwide, with 22,090 enrolled providers across 56 states and an average of 1,420 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.
