ALITHEA GABRELLAS, MD appears in the CMS NPPES registry as a Infectious Disease Physician provider holding MD credentials at CORNER OF ROUTE N12 AND N7, FORT DEFIANCE, AZ, 86504, with a listed phone of (928) 729-8000. NPI 1568780641 was issued on 05/13/2010.

Medicare Part D records for calendar year 2023 show 187 prescription claims written by this provider, covering 74 Medicare beneficiaries and totaling roughly $104K in drug spend. 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 73.1296/100 for the 2023 performance year (Quality 69.6371, Cost 49.4306), compared with the national average of 83.1.

Infectious Disease Physician is a mid-sized specialty nationwide, with 8,292 enrolled providers across 54 states and an average of 816 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.
