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).

SHAHEEN CHOWDHURY is a Hospitalist Physician provider practicing in CAMBRIDGE, Massachusetts, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1740930999. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

SHAHEEN CHOWDHURY appears in the CMS NPPES registry as a Hospitalist Physician provider at 1493 CAMBRIDGE ST, CAMBRIDGE, MA, 02139, with a listed phone of (617) 665-1000. NPI 1740930999 was issued on 03/28/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHOWDHURY 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 135 prescription claims written by this provider, covering 38 Medicare beneficiaries and totaling roughly $33K in drug spend, split 30% brand-name and 70% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Hospitalist Physician is a mid-sized specialty nationwide, with 16,825 enrolled providers across 54 states and an average of 888 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.
