So, what’s covered? Basics of Medicare Part D

Medicare Part D plays a crucial role in providing prescription drug coverage for Medicare beneficiaries. In this comprehensive guide, we’ll explore the intricacies of Medicare Part D, including what it is, what it covers, and how to enroll.

What is Medicare Part D?

Medicare Part D is a prescription drug coverage program offered by private insurance companies. It is designed to help Medicare beneficiaries manage the costs of prescription medications. Enrollees can choose a standalone Part D plan to complement their Original Medicare coverage (Part A for hospital insurance and Part B for medical insurance). Or they can opt for a Medicare Advantage plan that includes prescription drug coverage.

What drugs does Medicare Part D cover?

Every Medicare Part D plan is required to offer a minimum of two medications from the majority of drug categories, ensuring a broad range of coverage. Additionally, these plans must encompass all available drugs within specific crucial categories, including antidepressants, antipsychotic medications, immunosuppressant drugs, HIV/AIDS treatment, and anticancer drugs. This mandate ensures that beneficiaries have access to essential medications across these vital therapeutic areas, promoting comprehensive healthcare coverage under Medicare Part D.

You’ll find that Medicare Part D covers a wide range of prescription drugs, including both brand-name and generic medications. Your Part D coverage includes medications that are medically necessary to treat various health conditions —  drugs that are typically categorized into different tiers, each with a different cost-sharing amount. It’s important for beneficiaries to review the formulary (list of covered drugs) of their chosen plan to ensure their medications are included.

Here’s a list of drug types covered by Medicare Part D:

  • Generic and Brand-Name Drugs: Both generic and brand-name prescription drugs are covered, offering beneficiaries a range of options.
  • Vaccines: Some vaccines that are not covered by Medicare Part B may be covered under Part D.
  • Specialty Medications: Part D plans often cover high-cost specialty medications for chronic or complex conditions.
  • Mail-Order Prescriptions: Many Part D plans offer the convenience of mail-order services for prescription refills.

What Medicare Part D Won’t Cover

While Medicare Part D provides substantial coverage for prescription drugs, there are certain exclusions. It’s important for beneficiaries to be aware of what Medicare Part D doesn’t cover:

  • Over-The-Counter (OTC) Medications: Most OTC medications are not covered by Part D.
  • Certain High-Cost Drugs: Some very high-cost medications may not be fully covered, and beneficiaries may face significant out-of-pocket expenses.
  • Drugs Covered by Other Parts of Medicare: Medications administered in a hospital or doctor’s office, typically covered under Medicare Part B, are not covered by Part D.

How to Enroll in Medicare Part D

Enrolling in Medicare Part D involves a few key steps:

  1. Eligibility: To enroll in Part D, individuals must be eligible for Medicare. Most people become eligible when they turn 65, but individuals under 65 with specific disabilities may also qualify.
  2. Open Enrollment Periods: Beneficiaries can enroll in or make changes to their Part D coverage during three specific periods, such as the Initial Enrollment Period, the Annual Enrollment Period, and the Open Enrollment Period. Plus, there is a fourth, more fluid time: the Special Enrollment Period.
  3. Choosing a Plan: Researching and comparing Part D plans offered by different insurance companies is a necessary step. Factors to consider include the plan’s formulary, cost-sharing structure, and pharmacy network.
  4. Enrollment Options: Beneficiaries can enroll in Medicare Part D by contacting individual insurance companies directly or by calling 1-800-MEDICARE. Or why not have Guided Solutions do the legwork for you
