How MIPS and board certification work
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).
Melanie Halker appears in the CMS NPPES registry as a Family Nurse Practitioner provider at 1250 S WASHINGTON ST, Van Wert, OH, 45891, with a listed phone of (419) 238-2390. NPI 1679134092 was issued on 06/26/2019.
Medicare Part D records for calendar year 2023 show 1,813 prescription claims written by this provider, covering 372 Medicare beneficiaries and totaling roughly $53K in drug spend, split <1% brand-name and >99% generic by claim count, with an opioid prescribing rate of 39.5%. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 88.3/100 for the 2023 performance year (Quality 83.4, Cost 77.6), compared with the 83.5 average among clinicians with a measured score.

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.

Before you book an appointment
Use this federal record as your verification checklist, not as a recommendation.
- Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
- Check the active license and any disciplinary history with the Ohio medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Family Nurse Practitioner peer on Medicare volume and prescribing patterns. Compare providers
