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).

SANDRA HERRINGTON, M.D. appears in the CMS NPPES registry as a Radiation Oncology Physician provider holding M.D. credentials at 803 W MARKET ST, LIMA, OH, 45805, with a listed phone of (419) 996-5063. NPI 1104809904 was issued on 11/25/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HERRINGTON 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 132 prescription claims written by this provider, covering 48 Medicare beneficiaries and totaling roughly $2K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 26.5%. 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 68.1616/100 for the 2023 performance year (Quality 42.112), compared with the national average of 83.1.

Radiation Oncology Physician is a mid-sized specialty nationwide, with 6,018 enrolled providers across 52 states and an average of 186 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.
