Meghan Brennan, M.D. appears in the CMS NPPES registry as a Infectious Disease Physician provider holding M.D. credentials at 600 HIGHLAND AVE, Madison, WI, 53792, with a listed phone of (608) 263-0946. NPI 1033154356 was issued on 06/19/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Brennan 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 176 prescription claims written by this provider, covering 35 Medicare beneficiaries and totaling roughly $33K in drug spend, split 10% brand-name and 90% 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.

Infectious Disease Physician is a mid-sized specialty nationwide, with 8,292 enrolled providers across 54 states and an average of 816 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
