How MIPS and board certification work
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 Wilcox appears in the CMS NPPES registry as a Clinical Genetics (M.D.) Physician provider at 2165 N DECATUR RD, Decatur, GA, 30033, with a listed phone of (404) 778-8500. NPI 1205896933 was issued on 03/25/2006.
Medicare Part D records for calendar year 2023 show 157 prescription claims written by this provider, covering 14 Medicare beneficiaries and totaling roughly $3.8 million in drug spend, split 84% brand-name and 16% generic by claim count.

Clinical Genetics (M.D.) Physician is a narrow specialty nationwide, with 825 enrolled providers across 50 states and an average of 261 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
