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).

MICHAEL KITTAY, MD appears in the CMS NPPES registry as a Addiction Medicine (Psychiatry & Neurology) Physician provider holding MD credentials at 39 SIMON ST, NASHUA, NH, 03060, with a listed phone of (603) 888-4347. NPI 1376601500 was issued on 12/04/2006.

Medicare Part D records for calendar year 2023 show 694 prescription claims written by this provider, covering 23 Medicare beneficiaries and totaling roughly $40K in drug spend, split 4% brand-name and 96% generic by claim count.

Addiction Medicine (Psychiatry & Neurology) Physician is a narrow specialty nationwide, with 658 enrolled providers across 49 states and an average of 1,019 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.
