WILLIAM DILLIN, M.D. appears in the CMS NPPES registry as a Orthopaedic Surgery of the Spine Physician provider holding M.D. credentials at 7901 JOHN W CARPENTER FWY, DALLAS, TX, 75247, with a listed phone of (972) 838-1132. NPI 1962473827 was issued on 01/30/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DILLIN 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 61 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $418 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 79.2279/100 for the 2023 performance year (Quality 74.4555, Cost 62.1376), 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.
