JOHN PORTER, MD appears in the CMS NPPES registry as a Pain Medicine (Physical Medicine & Rehabilitation) Physician provider holding MD credentials at 6527 W BLOOMFIELD RD, GLENDALE, AZ, 85304, with a listed phone of (623) 764-2894. NPI 1700940541 was issued on 12/19/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PORTER 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 29 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $529 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 93.3786/100 for the 2023 performance year (Quality 94.5781, Cost 62.1452), compared with the national average of 83.1.

Pain Medicine (Physical Medicine & Rehabilitation) Physician is a narrow specialty nationwide, with 1,626 enrolled providers across 50 states and an average of 1,401 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.
