Conclusion
Medicare Part D is a Medicare plan that helps you pay for prescription medications that are not under original Medicare (parts A and B). You can combine certain private medication plans with your original Medicare coverage, or select a Medicare Advantage plan (Part C) with drug coverage. You can also receive certain coverage for your vision and dental health.
