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).

JAMES BAKER, MD is a Psychiatry Physician provider practicing in THORNTON, Colorado, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1053453928. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

JAMES BAKER, MD appears in the CMS NPPES registry as a Psychiatry Physician provider holding MD credentials at 8989 HURON ST, THORNTON, CO, 80260, with a listed phone of (303) 853-3500. NPI 1053453928 was issued on 02/13/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BAKER most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 2,545 prescription claims written by this provider, covering 39 Medicare beneficiaries and totaling roughly $454K in drug spend, split 4% brand-name and 96% generic by claim count.

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.
