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).

AJAY LINGIREDDY, MD appears in the CMS NPPES registry as a Hematology & Oncology Physician provider holding MD credentials at 301 UNIVERSITY BOULEVARD, GALVESTON, TX, 77555, with a listed phone of (832) 505-1910. NPI 1841814365 was issued on 06/01/2020.

Medicare Part D records for calendar year 2023 show 234 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $27K 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.

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.
