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).

  • Check the active license and any disciplinary history with the Pennsylvania medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Acupuncturist peer on Medicare volume and prescribing patterns. Compare providers
