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 DANZ, WHNP appears in the CMS NPPES registry as a Women's Health Nurse Practitioner provider holding WHNP credentials at 13526 CRESCENT MOON DR, BIGFORK, MT, 59911, with a listed phone of (218) 779-7623. NPI 1386073716 was issued on 11/06/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DANZ most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 133 prescription claims written by this provider, covering 73 Medicare beneficiaries and totaling roughly $14K in drug spend, split 63% brand-name and 37% generic by claim count.

Women's Health Nurse Practitioner is a mid-sized specialty nationwide, with 9,452 enrolled providers across 55 states and an average of 262 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.
