IRVIN TANTUCO, MD appears in the CMS NPPES registry as a Sleep Medicine (Internal Medicine) Physician provider holding MD credentials at 1213 HERMANN DR STE 610, HOUSTON, TX, 77004, with a listed phone of (713) 524-3900. NPI 1508025412 was issued on 06/05/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TANTUCO 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 2,646 prescription claims written by this provider, covering 287 Medicare beneficiaries and totaling roughly $517K in drug spend, split 15% brand-name and 85% generic by claim count, with an opioid prescribing rate of 4.1%. 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 78.8739/100 for the 2023 performance year (Quality 91.487, Cost 33.4335), compared with the national average of 83.1.

Sleep Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 857 enrolled providers across 52 states and an average of 1,310 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.
