About this data. The prescription history for DR. ELIZABETH DENNIS D.O. 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.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter.

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