Ralf Habermann, MD appears in the CMS NPPES registry as a Geriatric Medicine (Internal Medicine) Physician provider holding MD credentials at 3601 THE VANDERBILT CLINIC, Nashville, TN, 37232, with a listed phone of (615) 322-3000. NPI 1750394060 was issued on 08/15/2006.

Medicare Part D records for calendar year 2023 show 261 prescription claims written by this provider, covering 33 Medicare beneficiaries and totaling roughly $30K in drug spend, split 19% brand-name and 74% 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 97.1/100 for the 2023 performance year (Quality 85.6), compared with the national average of 83.1.

Geriatric Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 4,161 enrolled providers across 52 states and an average of 4,450 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
