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).

MATTHEW ADLESTEIN is a Internal Medicine Physician provider practicing in BOSTON, Massachusetts, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1609295435.

MATTHEW ADLESTEIN appears in the CMS NPPES registry as a Internal Medicine Physician provider at 330 BROOKLINE AVE # SPAN2, BOSTON, MA, 02215, with a listed phone of (781) 528-2722. NPI 1609295435 was issued on 04/09/2014.

Medicare Part D records for calendar year 2023 show 282 prescription claims written by this provider, covering 122 Medicare beneficiaries and totaling roughly $18K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 5.7%.

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.
