Does Medicare Advantage include Part D, or do I need a separate plan?

Most Medicare Advantage plans already include Part D drug coverage. If yours does, do not add a separate drug plan, because that can get you dropped from Advantage.

Key points

There are two ways to get Medicare drug coverage, and most Medicare Advantage plans already include it.
If your Advantage plan covers drugs and you sign up for a separate Part D plan, Medicare will usually drop you from the Advantage plan and send you back to Original Medicare.
One two minute call to your plan's member services line tells you for sure whether your plan includes Part D.

Most Medicare Advantage plans already include Part D drug coverage, so you do not need a separate drug plan. If you stay on Original Medicare instead, you add a standalone Part D plan, a drug plan sold on its own.

Route one: drug coverage bundled in an Advantage plan (MAPD)

Most Medicare Advantage plans include prescription coverage. These are called Medicare Advantage Prescription Drug plans, or MAPD plans. You get one plan and one card for both the doctor and the pharmacy.

The drug side still has its own rules. It has a formulary, the plan's list of covered drugs, and tiers, the price groups those drugs are sorted into. It also has its own deductible, the amount you pay before the plan starts paying, and its own yearly cap on what you pay out of pocket. All of that is separate from what you pay for doctor visits and hospital care.

Route two: a standalone Part D plan with Original Medicare

If you stay on Original Medicare, usually with a Medicare Supplement, a policy that pays the bills Medicare leaves to you, you add a standalone Part D plan. That plan is separate. It has its own premium, the monthly bill for the coverage, and its own card. See how Part D works.

The mistake that disenrolls people from their Advantage plan

Say your Advantage plan already includes drug coverage, and you sign up for a standalone Part D plan on top of it. Medicare will usually drop you from the Advantage plan and send you back to Original Medicare.

Medicare does this on purpose. It treats a new standalone drug plan as a sign that you want to leave the Advantage plan. You are left with no supplement, no cap on your medical costs, and no easy way back until the next enrollment window.

There are a few narrow exceptions, mainly certain preferred provider organization (PPO) plans and private fee for service plans that are sold without drug coverage. Confirm your plan type before you assume either way.

Which route fits which situation

The drug route follows from the bigger choice you make between Medicare Advantage and Original Medicare.

If you choose Advantage, take a plan with drugs included unless you have a specific reason not to.
If you choose Original Medicare with a supplement, you need a standalone plan, and you can pick it purely for your medications.

See how the two paths compare.

One advantage of the standalone route

You can change drug plans every year based only on your medications. Your doctors and your medical coverage stay the same.

With a bundled plan, the drug coverage and the medical network, the list of doctors and hospitals the plan has contracts with, come as one package. If the drug list gets worse but the doctors are still good, you have to choose between them.

How to tell what you have

Look at your member card and your plan name. If it says MAPD, or if you use the same card at the doctor and at the pharmacy, your drugs are bundled. If you carry a separate card just for the pharmacy, you have a standalone plan.

When in doubt, call member services and ask whether your plan includes Part D. It takes two minutes.

Common follow-up questions

What happens if I enroll in both?

You will usually be dropped from the Advantage plan and sent back to Original Medicare, with no supplement to cover the gaps. Call your plan before you sign up for anything new.

Can I keep my standalone drug plan if I join an Advantage plan?

Usually not, if the Advantage plan includes drug coverage. The bundled coverage takes its place.

Which gives better drug coverage?

Neither one is better on its own. A standalone plan lets you choose purely for your medications, which helps if your drug list is unusual.
