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).

BRIAN MEDERNACH, BRIAN MEDERNACH appears in the CMS NPPES registry as a Pediatrics Physician provider holding BRIAN MEDERNACH credentials at 2160 S 1ST AVE, MAYWOOD, IL, 60153, with a listed phone of (708) 216-9000. NPI 1801050539 was issued on 07/11/2008.
