Specialty board-certified rate — Physician Assistant estimate
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus Maintenance of Certification cycles. CMS does not publish a per-provider board-certification field; the figure shown is the specialty-level estimated rate from ABMS / AOA reference data.
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).
Laura McIlwain, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at MEDICAL CENTER BLVD, Winston Salem, NC, 27157, with a listed phone of (336) 713-5440. NPI 1033453907 was issued on 11/16/2012.
