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).

NASIM REEDY, D.O. appears in the CMS NPPES registry as a Allergy & Immunology Physician provider holding D.O. credentials at 806 W DIAMOND AVE, GAITHERSBURG, MD, 20878, with a listed phone of (727) 215-7280.
