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).
Erika Hannigan appears in the CMS NPPES registry as a Registered Nurse provider at 18660 BAGLEY RD STE 102B, Cleveland, OH, 44130, with a listed phone of (440) 826-0742. NPI 1215582150 was issued on 08/07/2019.
Medicare Part D records for calendar year 2023 show 2,487 prescription claims written by this provider, covering 392 Medicare beneficiaries and totaling roughly $2.4 million in drug spend, split 16% brand-name and 83% generic by claim count, with an opioid prescribing rate of 2.1%. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 37.1/100 for the 2023 performance year (Quality 14.4, Cost 84.2), compared with the national average of 83.1.
Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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 Registered Nurse peer on Medicare volume and prescribing patterns. Compare providers
