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).

KRISTEN BOMMARITO is a Medical Physician Assistant provider practicing in LITTLETON, Colorado, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1518418599.

KRISTEN BOMMARITO appears in the CMS NPPES registry as a Medical Physician Assistant provider at 15 W DRY CREEK CIR, LITTLETON, CO, 80120, with a listed phone of (303) 952-1100. NPI 1518418599 was issued on 10/14/2016.

Medicare Part D records for calendar year 2023 show 355 prescription claims written by this provider, covering 98 Medicare beneficiaries and totaling roughly $147K in drug spend, split 60% brand-name and 40% generic by claim count.

Medical Physician Assistant is a mid-sized specialty nationwide, with 40,527 enrolled providers across 55 states and an average of 1,077 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.
