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).

ABIGAIL BUCHWACH, M.D. appears in the CMS NPPES registry as a Hospitalist Physician provider holding M.D. credentials at 1775 DEMPSTER ST, PARK RIDGE, IL, 60068, with a listed phone of (847) 723-2210.

Medicare Part D records for calendar year 2023 show 130 prescription claims written by this provider, covering 67 Medicare beneficiaries and totaling roughly $6K in drug spend.
