Medicare Part D Prescription Plans


Out of an abundance of caution and to mitigate the spread of the coronavirus, or COVID-19, certain Chickasaw Nation events, classes, facilities, etc., will be postponed, canceled or closed. For a complete list of postponements, cancellations or closures, visit the COVID-19 INFORMATION page. We will continue to update the list as the situation progresses.

Chickasaw citizens eligible to participate in a Medicare Part D prescription drug plan may request unbiased assistance with enrollment in the most suitable plan per their individual needs. Patient Benefit Assistants (PBAs) with the Chickasaw Nation are available to answer questions and help with applications after the following criteria have been met:

You Provide

  • Chickasaw citizenship card
  • Physical address (P.O. Box cannot be accepted)
  • Previous two years’ income information
  • Current and comprehensive prescription medication list


  • Medicare eligible, either age or disability category

Other Information


  • If you already have a Medicare D plan, the plan cannot be changed until open enrollment begins in October.
  • If you are Medicare eligible, and do NOT have an active Medicare D plan, there is no deadline to apply; although Medicare encourages annual open enrollment beginning in October.
