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).

HEATHER CARPENTER, PA-C appears in the CMS NPPES registry as a Medical Physician Assistant provider holding PA-C credentials at 4407 MACCORKLE AVE SE, CHARLESTON, WV, 25304, with a listed phone of (049) 250-3923. NPI 1659701738 was issued on 11/26/2013.

Medicare Part D records for calendar year 2023 show 34 prescription claims written by this provider, covering 19 Medicare beneficiaries and totaling roughly $3K in drug spend.

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.
