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).

CATHERINE MILLER, APRN, CNP appears in the CMS NPPES registry as a Psychiatric/Mental Health Clinical Nurse Specialist provider holding APRN, CNP credentials at 632 WAGNER AVE, GREENVILLE, OH, 45331, with a listed phone of (937) 365-2275. NPI 1972295038 was issued on 05/25/2023.

Medicare Part D records for calendar year 2023 show 196 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $55K in drug spend, split 18% brand-name and 82% generic by claim count.

Psychiatric/Mental Health Clinical Nurse Specialist is a narrow specialty nationwide, with 980 enrolled providers across 50 states and an average of 1,050 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.
