Drug Costs Depend On
Part D is Medicare-approved coverage for prescription drugs, which you can get through a stand-alone Part D plan or a Medicare Advantage plan.
- The drugs you use.
- The plan you choose.
- Whether you go to a pharmacy in your plan’s network.
- Whether the drugs you use are on your plan’s formulary.
- Whether you get extra help paying your Medicare Part D costs.
If your Medicare Advantage Plan (Part C) includes prescription drug coverage and you join a Medicare Prescription Drug Plan (Part D), you’ll be disenrolled from your Medicare Advantage Plan and returned to Original Medicare. If you decide not to join a Medicare Prescription Drug Plan when you’re first eligible, and you don’t have other creditable prescription drug coverage, or you don’t get Extra Help, you’ll likely pay a late enrollment penalty.
