MIPS final score (Gastroenterology Physician) — 76.0183/100 vs national avg 83.1

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).

OTTO TRINKL, M.D. appears in the CMS NPPES registry as a Gastroenterology Physician provider holding M.D. credentials at 590 COURT ST, KEENE, NH, 03431, with a listed phone of (603) 354-5454. NPI 1366476541 was issued on 07/11/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TRINKL 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 432 prescription claims written by this provider, covering 135 Medicare beneficiaries and totaling roughly $72K in drug spend, split 17% brand-name and 83% generic by claim count.

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 76.0183/100 for the 2023 performance year (Quality 65.3198, Cost 54.7412), compared with the national average of 83.1.

Gastroenterology Physician is a mid-sized specialty nationwide, with 16,567 enrolled providers across 54 states and an average of 833 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.
