SANTHOSH MANNEM, MD appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding MD credentials at 6500 HOSPITAL DR, HANNIBAL, MO, 63401, with a listed phone of (573) 629-3300. NPI 1518242957 was issued on 10/17/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MANNEM 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 3,810 prescription claims written by this provider, covering 394 Medicare beneficiaries and totaling roughly $405K in drug spend, split 13% brand-name and 87% 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 79.2637/100 for the 2023 performance year (Quality 92.172, Cost 29.642), compared with the national average of 83.1.

Interventional Cardiology Physician is a narrow specialty nationwide, with 3,382 enrolled providers across 53 states and an average of 2,984 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.
