PETER MCDONNELL, MD appears in the CMS NPPES registry as a General Practice Physician provider holding MD credentials at 4901 FOREST PARK AVE, SAINT LOUIS, MO, 63108, with a listed phone of (314) 362-5060. NPI 1417317249 was issued on 03/07/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MCDONNELL 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 2,094 prescription claims written by this provider, covering 213 Medicare beneficiaries and totaling roughly $260K in drug spend, split 15% brand-name and 85% generic by claim count, with an opioid prescribing rate of 5.0%. 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 79.292/100 for the 2023 performance year (Quality 71.46, Cost 59.5132), compared with the national average of 83.1.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 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.
