Specialty board-certified rate — Addiction Medicine (Internal Medicine) Physician estimate
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus Maintenance of Certification cycles. CMS does not publish a per-provider board-certification field; the figure shown is the specialty-level estimated rate from ABMS / AOA reference data.
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 DESHIELDS, M.D. appears in the CMS NPPES registry as a Addiction Medicine (Internal Medicine) Physician provider holding M.D. credentials at 801 NEW YORK AVE, TRENTON, NJ, 08638, with a listed phone of (609) 393-8000. NPI 1245345743 was issued on 08/21/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DESHIELDS 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 645 prescription claims written by this provider, covering 41 Medicare beneficiaries and totaling roughly $74K in drug spend, split 4% brand-name and 96% generic by claim count, with an opioid prescribing rate of 4.2%. 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.
Addiction Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 553 enrolled providers across 46 states and an average of 1,403 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.
