JEFFREY NAU, M.D. appears in the CMS NPPES registry as a Otolaryngology Physician provider holding M.D. credentials at 3999 DUTCHMANS LN, SUITE #3A, LOUISVILLE, KY, 40207, with a listed phone of (502) 897-7300. NPI 1184763658 was issued on 02/05/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NAU 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 669 prescription claims written by this provider, covering 250 Medicare beneficiaries and totaling roughly $15K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 2.8%. 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 49.7237/100 for the 2023 performance year (Quality 50.9198, Cost 64.826), compared with the national average of 83.1.

Otolaryngology Physician is a mid-sized specialty nationwide, with 10,895 enrolled providers across 54 states and an average of 509 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.
