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).

KIRA MAILEY, M.D. is a Nephrology Physician provider practicing in SAINT LOUIS, Missouri, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1457348286. 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.

KIRA MAILEY, M.D. appears in the CMS NPPES registry as a Nephrology Physician provider holding M.D. credentials at 18 CHAPEL HILL EST, SAINT LOUIS, MO, 63131, with a listed phone of (636) 939-3166. NPI 1457348286 was issued on 10/06/2005.

Medicare Part D records for calendar year 2023 show 141 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $14K in drug spend, split 21% brand-name and 79% generic by claim count.

Nephrology Physician is a mid-sized specialty nationwide, with 10,534 enrolled providers across 55 states and an average of 1,454 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.
