JOHN POWELL, MD appears in the CMS NPPES registry as a Radiation Oncology Physician provider holding MD credentials at 101 DATES DR, ITHACA, NY, 14850, with a listed phone of (607) 274-4060. NPI 1851557615 was issued on 07/31/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what POWELL 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 72 prescription claims written by this provider, covering 34 Medicare beneficiaries and totaling roughly $3K in drug spend, with an opioid prescribing rate of 18.1%. 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 95.2197/100 for the 2023 performance year (Quality 84.6968), compared with the national average of 83.1.

Radiation Oncology Physician is a mid-sized specialty nationwide, with 6,018 enrolled providers across 52 states and an average of 186 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.
