DAVID PRIOR, MD appears in the CMS NPPES registry as a Orthopaedic Surgery of the Spine Physician provider holding MD credentials at 33300 N 32ND AVE STE 320, PHOENIX, AZ, 85085, with a listed phone of (602) 648-5444. NPI 1467772392 was issued on 06/02/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PRIOR 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 80 prescription claims written by this provider, covering 43 Medicare beneficiaries and totaling roughly $575 in drug spend, with an opioid prescribing rate of 35.0%. 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 78.3512/100 for the 2023 performance year (Quality 76.0997, Cost 51.7376), compared with the national average of 83.1.

Orthopaedic Surgery of the Spine Physician is a narrow specialty nationwide, with 1,773 enrolled providers across 51 states and an average of 362 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.
