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).

ADAKU NWACHUKU, D.O. appears in the CMS NPPES registry as a Pain Medicine (Physical Medicine & Rehabilitation) Physician provider holding D.O. credentials at 8222 SCHULTZ RD STE 100A, CLINTON, MD, 20735, with a listed phone of (202) 221-8442. NPI 1184850505 was issued on 06/01/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NWACHUKU 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 5,034 prescription claims written by this provider, covering 294 Medicare beneficiaries and totaling roughly $365K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 52.4%. 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.

Pain Medicine (Physical Medicine & Rehabilitation) Physician is a narrow specialty nationwide, with 1,626 enrolled providers across 50 states and an average of 1,401 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.
