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).

VIMAL MASTER SANKAR RAJ, MD appears in the CMS NPPES registry as a Pediatric Nephrology Physician provider holding MD credentials at 530 NE GLEN OAK AVE, PEORIA, IL, 61637, with a listed phone of (309) 624-8884. NPI 1336339597 was issued on 07/25/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MASTER SANKAR RAJ 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 34 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $24K in drug spend. 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 87.0887/100 for the 2023 performance year (Quality 70.7998, Cost 52.8291), compared with the national average of 83.1.

Pediatric Nephrology Physician is a narrow specialty nationwide, with 723 enrolled providers across 50 states and an average of 97 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.
