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).

CAITLIN ANDRYKA, PA-C is a Physician Assistant provider practicing in LITTLE ROCK, Arkansas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: PA-C. NPI: 1326449182. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

CAITLIN ANDRYKA, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 6 SHACKLEFORD DR, LITTLE ROCK, AR, 72211, with a listed phone of (501) 500-5001. NPI 1326449182 was issued on 09/11/2014.

Medicare Part D records for calendar year 2023 show 562 prescription claims written by this provider, covering 104 Medicare beneficiaries and totaling roughly $1.4 million in drug spend, split 40% brand-name and 60% generic by claim count.

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.
