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).

SAMEH ATTIA, M.D. is a Internal Medicine Physician provider practicing in KNOXVILLE, Tennessee, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

SAMEH ATTIA, M.D. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding M.D. credentials at 1940 ALCOA HWY STE E210, KNOXVILLE, TN, 37920, with a listed phone of (865) 524-7471. NPI 1396085700 was issued on 02/21/2013.
