GREGORY LARRIEUX appears in the CMS NPPES registry as a Transplant Surgery Physician provider at 9200 W WISCONSIN AVE, MILWAUKEE, WI, 53226, with a listed phone of (414) 805-8632. NPI 1699118174 was issued on 04/15/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LARRIEUX 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 195 prescription claims written by this provider, covering 45 Medicare beneficiaries and totaling roughly $27K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 16.9%. 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 83.8451/100 for the 2023 performance year (Quality 84.5974, Cost 58.6394), compared with the national average of 83.1.

Transplant Surgery Physician is a narrow specialty nationwide, with 1,026 enrolled providers across 48 states and an average of 275 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
