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).

KAREN COZELOS, NP-C appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding NP-C credentials at 2845 SIENA HEIGHTS DR STE 21002200, HENDERSON, NV, 89052, with a listed phone of (702) 877-5199. NPI 1912655523 was issued on 03/13/2022.

Medicare Part D records for calendar year 2023 show 423 prescription claims written by this provider, covering 171 Medicare beneficiaries and totaling roughly $23K in drug spend.

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.
