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).

CONNOR DUGAN, MD is a Glaucoma Specialist (Ophthalmology) Physician provider practicing in RALEIGH, North Carolina, according to the CMS National Plan and Provider Enumeration System (NPPES).

CONNOR DUGAN, MD appears in the CMS NPPES registry as a Glaucoma Specialist (Ophthalmology) Physician provider holding MD credentials at 3320 EXECUTIVE DR STE 111, RALEIGH, NC, 27609, with a listed phone of (919) 876-2427. NPI 1710507686 was issued on 04/21/2020.
