Mark Timm, M.D. appears in the CMS NPPES registry as a Surgery Physician provider holding M.D. credentials at W180N7950 TOWN HALL RD, Menomonee Falls, WI, 53051, with a listed phone of (262) 255-2500. NPI 1093780124 was issued on 02/22/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Timm 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 100 prescription claims written by this provider, covering 70 Medicare beneficiaries and totaling roughly $9K in drug spend, split 39% brand-name and 61% generic by claim count, with an opioid prescribing rate of 19.0%. 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.

Surgery Physician is a mid-sized specialty nationwide, with 36,191 enrolled providers across 56 states and an average of 169 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
