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).

DREW CALHOUN, M.D. appears in the CMS NPPES registry as a Student in an Organized Health Care Education/Training Program provider holding M.D. credentials at 10200 NE 132ND ST, KIRKLAND, WA, 98034, with a listed phone of (800) 435-7221. NPI 1992144984 was issued on 06/23/2013.

Medicare Part D records for calendar year 2023 show 241 prescription claims written by this provider, covering 29 Medicare beneficiaries and totaling roughly $19K in drug spend, split 5% brand-name and 95% generic by claim count.

Student in an Organized Health Care Education/Training Program is a high-volume specialty nationwide, with 331,761 enrolled providers across 55 states and an average of 459 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.
