Can I enroll in an HMO Medicare Advantage plan and then add prescription drug coverage through a stand-alone Medicare Part D plan?

No.  Medicare Advantage plans are available in two general varieties: Medicare Advantage plans with prescription drug coverage (MAPDs) and Medicare Advantage plans without prescription drug coverage (MAs).

If you enroll in an “MA” plan (a Medicare Advantage plan with no drug coverage), you are not able to add a separate Medicare Part D plan unless the MA plan is a Private Fee-for-Service (PFFS) Medicare Advantage plan without drug coverage or a Medical Savings Account (MSA) plan.

If you are enrolled in a Medicare Advantage HMO or Medicare Advantage PPO  plan, enrolling in stand-alone Medicare Part D  plan will automatically disenroll you from your Medicare Advantage plan and return you to original Medicare Part A and Medicare Part B.

Likewise, if you have a stand-alone Medicare Part D plan (PDP) and try to join a Medicare Advantage HMO or PPO plan, you will lose your Medicare Part D coverage automatically.

A few more details...

Since you cannot join an HMO or PPO Medicare Advantage plan that does not provide prescription coverage and also enroll in a stand-alone Medicare Part D plan, why would anyone enroll in an HMO or PPO MA?  The HMO or PPO MA may be an option for Medicare beneficiaries who already receive their prescription drug coverage from another source other than a stand-alone Medicare Part D plan.

The Medicare & You Handbook describes each type of Medicare Advantage plan and each has a section
Are prescription drugs covered?

  • HMO plans - it states, "In most cases, yes. If you want Medicare drug coverage, you must join an HMO plan that offers prescription drug coverage."

  • PPO plans -  "In most cases, yes. If you want Medicare drug coverage, you must join a PPO plan that offers prescription drug coverage."

  • PFFS plans - are a different story. "Sometimes. If your PFFS plan doesn't offer drug coverage, you can join a stand-alone Medicare Prescription Drug plan (PDP) to get coverage."

  • SNP - "Yes. All SNPs must provide Medicare prescription drug coverage (Part D).
If you wish to find the Medicare Advantage plans in your area, you can use our MA-Finder: MA-Finder.com. To see if a Medicare Advantage plan includes prescription drug coverage.

You can also browse for a Medicare Advantage plan by the counties in your state. Here is an example of the Medicare Advantage plans for Florida counties: MA-Finder.com/FL or Texas using MA-Finder.com/TX, etc.

And a bit of Medicare history...
The 2010 Medicare & You Handbook is a little confusing.  On page 43 it notes that for Medicare Advantage plans “like an HMO or PPO” you need, as the second step to “Decide If You Want Prescription Drug Coverage (Part D)” and "[i]f you want prescription drug coverage, and it’s offered by your plan, in most cases you must get it through your plan. If your plan doesn’t offer drug coverage, you can choose and join a Medicare Prescription Drug Plan. See pages 55–57."

However, on page 55 of the 2010 Medicare & You Handbook, the subject of HMO and PPO Medicare Advantage plans are addressed and the handbook notes more directly that: “If you want drug coverage, you must join an HMO Plan that offers prescription drug coverage.

We conclude that the earlier page 43 of the 2010 Medicare & You handbook is referring to Medicare Advantage plans in the form of Private Fee for Service plans (PFFS) - that may allow you to join a separate stand-alone Medicare Part D plan along with the Medicare Advantage plan.

Here is a quote from an earlier Medicare & You Handbook that provides the information more clearly:

"If you belong to a Medicare Advantage HMO or PPO, you can only get Medicare prescription drug coverage from your plan (if offered). If you join a stand-alone Medicare Prescription Drug Plan, you will be automatically disenrolled from your Medicare HMO or PPO and returned to the Original Medicare Plan."

As a note, in the early days of the Medicare Part D program (2005-2006), we heard from a number of Medicare advocates wondering why people joining Medicare Advantage HMOs immediately lost their Medicare Part D prescription drug coverage.

Bottom Line...
If you wish to join a Medicare Advantage plan HMO or PPO, then you should look for an HMO PPO MAPD plan that also covers prescription drugs.
