About this data. The prescription history for DR. OFER ZIMMERMAN MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release.

Always confirm current medications and costs directly with the provider and your plan.
