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).

MARK BIELAWSKI, APRN appears in the CMS NPPES registry as a Primary Care Nurse Practitioner provider holding APRN credentials at VETERANS ADMINISTRATION, NEWINGTON, CT, 06111, with a listed phone of (866) 808-7921. NPI 1326371261 was issued on 09/10/2009.

Medicare Part D records for calendar year 2023 show 85 prescription claims written by this provider, covering 23 Medicare beneficiaries and totaling roughly $11K in drug spend.
