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).

ANNA COX, PMHNP-BC appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding PMHNP-BC credentials at 8041 E BURNSIDE ST, PORTLAND, OR, 97215, with a listed phone of (503) 252-3304. NPI 1447313937 was issued on 12/18/2006.

Medicare Part D records for calendar year 2023 show 447 prescription claims written by this provider, covering 26 Medicare beneficiaries and totaling roughly $24K in drug spend, split 3% brand-name and 97% generic by claim count.

Psychiatric/Mental Health Nurse Practitioner is a mid-sized specialty nationwide, with 39,953 enrolled providers across 54 states and an average of 927 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.
