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).

WARREN HAGAN, M.D. is a Plastic Surgery Physician provider practicing in QUINCY, Illinois, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1164458105. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

WARREN HAGAN, M.D. appears in the CMS NPPES registry as a Plastic Surgery Physician provider holding M.D. credentials at 1132 BROADWAY ST, QUINCY, IL, 62301, with a listed phone of (217) 224-6423. NPI 1164458105 was issued on 06/23/2006.

Medicare Part D records for calendar year 2023 show 46 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $2K in drug spend, split 28% brand-name and 72% generic by claim count.

Plastic Surgery Physician is a mid-sized specialty nationwide, with 5,316 enrolled providers across 52 states and an average of 84 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
