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).

JOHN HOWELL, D.D.S. appears in the CMS NPPES registry as a Prosthodontics provider holding D.D.S. credentials at 2501 CRESTWOOD RD, NORTH LITTLE ROCK, AR, 72116, with a listed phone of (501) 812-0212. NPI 1578631453 was issued on 12/01/2006.

Medicare Part D records for calendar year 2023 show 36 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $435 in drug spend. 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.

Prosthodontics is a narrow specialty nationwide, with 3,510 enrolled providers across 51 states and an average of 85 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.
