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).

TERESA WILLIE, CNM appears in the CMS NPPES registry as a Advanced Practice Midwife provider holding CNM credentials at CORNER OF ROUTE N12 AND N7, FORT DEFIANCE, AZ, 86504, with a listed phone of (928) 729-8000. NPI 1417008541 was issued on 01/16/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WILLIE 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 51 prescription claims written by this provider, covering 22 Medicare beneficiaries and totaling roughly $11K in drug spend, split 75% brand-name and 25% generic by claim count.

Advanced Practice Midwife is a mid-sized specialty nationwide, with 10,893 enrolled providers across 55 states and an average of 99 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.
