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).

DOUGLAS IDDINGS, DO is a Surgical Oncology Physician provider practicing in FLINT, Michigan, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: DO.

DOUGLAS IDDINGS, DO appears in the CMS NPPES registry as a Surgical Oncology Physician provider holding DO credentials at 302 KENSINGTON AVE, FLINT, MI, 48503, with a listed phone of (810) 762-8092. NPI 1023233384 was issued on 04/13/2007.
