ALEXANDER DIAZ, MD, PHD appears in the CMS NPPES registry as a Radiation Oncology Physician provider holding MD, PHD credentials at 285 MEDICAL CENTER DR, PADUCAH, KY, 42003, with a listed phone of (270) 441-4343. NPI 1962908889 was issued on 03/30/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DIAZ 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 59 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $2K in drug spend, with an opioid prescribing rate of 27.1%. 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 76.8267/100 for the 2023 performance year (Quality 74.1809, Cost 49.408), 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.
