The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

WILLIAM PALMER, MD appears in the CMS NPPES registry as a Physical Medicine & Rehabilitation Physician provider holding MD credentials at 3333 SILAS CREEK PKWY, WINSTON-SALEM, NC, 27103, with a listed phone of (336) 718-5763. NPI 1518921584 was issued on 04/14/2006.

Medicare Part D records for calendar year 2023 show 3,162 prescription claims written by this provider, covering 496 Medicare beneficiaries and totaling roughly $150K in drug spend, with an opioid prescribing rate of 51.3%.

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 88.6277/100 for the 2023 performance year (Quality 74.5958), compared with the national average of 83.1.

Physical Medicine & Rehabilitation Physician is a mid-sized specialty nationwide, with 15,306 enrolled providers across 54 states and an average of 781 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.
