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).

JEFFREY MACEWEN, DO appears in the CMS NPPES registry as a Family Medicine Physician provider holding DO credentials at 915 4TH ST NW, CHOTEAU, MT, 59422, with a listed phone of (406) 466-6085. NPI 1609404714 was issued on 04/01/2020.

Medicare Part D records for calendar year 2023 show 912 prescription claims written by this provider, covering 186 Medicare beneficiaries and totaling roughly $80K in drug spend, with an opioid prescribing rate of 6.8%.

Family Medicine Physician is a high-volume specialty nationwide, with 147,640 enrolled providers across 56 states and an average of 3,418 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.
