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).

Angela Mark, MD appears in the CMS NPPES registry as a Student in an Organized Health Care Education/Training Program provider holding MD credentials at 1000 CENTRAL ST STE 880, Evanston, IL, 60201, with a listed phone of (847) 570-2570. NPI 1225155955 was issued on 03/26/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Mark 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 894 prescription claims written by this provider, covering 173 Medicare beneficiaries and totaling roughly $207K in drug spend, split 16% brand-name and 84% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 93.1/100 for the 2023 performance year (Quality 80.8), compared with the national average of 83.1.

Student in an Organized Health Care Education/Training Program is a high-volume specialty nationwide, with 331,761 enrolled providers across 55 states and an average of 459 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.

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 Illinois medical board — federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Student in an Organized Health Care Education/Training Program peer on Medicare volume and prescribing patterns. Compare providers
