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).

SARATH KUMAR JAGANATHAN JAISHANKAR, MD appears in the CMS NPPES registry as a Vascular Neurology Physician provider holding MD credentials at 530 NE GLEN OAK AVE, PEORIA, IL, 61637, with a listed phone of (309) 655-2000. NPI 1306465893 was issued on 04/14/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JAGANATHAN JAISHANKAR 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 161 prescription claims written by this provider, covering 37 Medicare beneficiaries and totaling roughly $15K in drug spend, split 7% brand-name and 93% 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.

Vascular Neurology Physician is a narrow specialty nationwide, with 555 enrolled providers across 47 states and an average of 378 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.
