Program Description

Montana’s Big Sky Rx Program, or BSRx for short, is a state pharmaceutical assistance program that helps seniors by providing financial assistance to cover the costs of their Medicare Part D premiums. Depending on the individual and the Medicare Part D plan in which they are enrolled, the financial assistance could pay as much as the entire monthly premium.  This program is managed by the Montana Department of Public Health and Human Services and is funded by a tax on tobacco products.

To be eligible for this program, seniors must meet the requirements that follow. Note that one’s assets, although requested on the application, are not considered an eligibility factor.

The state of Illinois has two programs designed to provide financial assistance to the elderly to help them purchase their prescription drugs.  Rx Basic is for individuals without Medicare insurance and the Rx Plus is designed for those on Medicare.

Rx Plus is known as a Medicare wraparound program which means the benefits wrap around those benefits provided by a Medicare Part D plan.  When making a prescription purchase, Medicare Part D is the first payer and then this program contributes towards those costs the Part D plan does not cover.
