A Part D plan may be purchased by anyone who has Medicare Part A and/or Part B and lives in a plan’s service area.

Although enrollment in a Part D plan is not required, a Part D plan may help lower your prescription drug expenses, as well as protect you against higher costs in the future. Even people who do not currently take any medications should consider joining a plan for three reasons:

  1. You may be charged a late-enrollment penalty (LEP) if you decide to join Part D at a later date unless you have had creditable coverage that is, coverage that meets Medicare's minimum standards since it is expected to pay, on average, at least as much as Medicare's standard prescription drug coverage.
  2. Illnesses and/or accidents are not uncommon even while practicing healthy lifestyle habits. Medications needed to treat an unplanned medical event could be expensive.
  3. Advances in pharmaceuticals continue to bring us effective medications, but many of these drugs carry a high price.

Not everyone needs a Part D plan, however. Some people on Medicare don’t need one of these plans because they already have other drug coverage, such as through a current or former employer.
