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).

STEVEN GAMMON, MD appears in the CMS NPPES registry as a Orthopaedic Surgery Physician provider holding MD credentials at 627 25 1/2 RD, GRAND JUNCTION, CO, 81505, with a listed phone of (970) 242-3535. NPI 1356552657 was issued on 05/25/2007.

Medicare Part D records for calendar year 2023 show 160 prescription claims written by this provider, covering 83 Medicare beneficiaries and totaling roughly $2K in drug spend, with an opioid prescribing rate of 51.3%.

Orthopaedic Surgery Physician is a mid-sized specialty nationwide, with 25,781 enrolled providers across 56 states and an average of 324 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.
