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 PEMBERTON, D.O. appears in the CMS NPPES registry as a Ophthalmic Plastic and Reconstructive Surgery Physician provider holding D.O. credentials at 4301 W MARKHAM ST # 523, LITTLE ROCK, AR, 72205, with a listed phone of (501) 686-8000. NPI 1528278322 was issued on 05/23/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PEMBERTON 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 337 prescription claims written by this provider, covering 159 Medicare beneficiaries and totaling roughly $9K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 14.8%.

Ophthalmic Plastic and Reconstructive Surgery Physician is a narrow specialty nationwide, with 291 enrolled providers across 46 states and an average of 624 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.
