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).
Charissa Montgomery appears in the CMS NPPES registry as a Medical-Surgical Registered Nurse provider at 333 COTTMAN AVE, Philadelphia, PA, 19111, with a listed phone of (215) 728-6900. NPI 1326558503 was issued on 10/02/2017.
Medicare Part D records for calendar year 2023 show 275 prescription claims written by this provider, covering 58 Medicare beneficiaries and totaling roughly $909K in drug spend, split 51% brand-name and 49% generic by claim count, with an opioid prescribing rate of 15.6%.

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 Pennsylvania medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Medical-Surgical Registered Nurse peer on Medicare volume and prescribing patterns. Compare providers
