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).

JOSEPH CHIPMAN, MD is a Neurology Physician provider practicing in CHARLOTTE, North Carolina, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD.

JOSEPH CHIPMAN, MD appears in the CMS NPPES registry as a Neurology Physician provider holding MD credentials at 1918 RANDOLPH RD, CHARLOTTE, NC, 28207, with a listed phone of (704) 384-9437. NPI 1871756759 was issued on 07/09/2008.
