Medicare AEP Closes December 7: What Your Clients Can and Cannot Change

What AEP allows

Start every review by stating the rules the same way each time. The Annual Enrollment Period runs October 15 through December 7, according to Medicare.gov and CMS. During that window a client can switch from one Medicare Advantage plan to another, move from Original Medicare into a Medicare Advantage plan, or leave Medicare Advantage and return to Original Medicare. They can also join, drop, or change a standalone Part D prescription drug plan. Coverage changes made during AEP generally take effect January 1 of the following year, so nothing you submit now changes what the client has today. That point matters in conversation, because some clients assume a new card means new coverage next week. Tell them plainly that their current plan stays in force through December 31, that claims and prescriptions in the meantime are handled under the current plan, and that the new plan begins on January 1. Say it, and put it in your follow-up note for the file.

What AEP does not do

Equally important is what the window does not do. Changes do not start before January 1, so a client who wants relief from a plan problem this month will not get it from an AEP switch. After AEP closes, the next opportunity is much narrower. From January 1 to March 31, the Medicare Advantage Open Enrollment Period, as CMS describes it, lets people already in a Medicare Advantage plan switch plans or return to Original Medicare. It is not a second chance for everyone. A client who stays in Original Medicare cannot use it to join a Medicare Advantage plan, and it does not apply to someone who only has a standalone drug plan. Say this directly: the choice they make by December 7 is the one they should expect to live with at least into the new year. Setting that expectation before you open Plan Finder keeps you from promising a fix the rules do not provide.

A worked example: 17 days, five checks

Walk through a real calendar with a client. Say a client calls you on November 20 with a Medicare Advantage plan and a new prescription. From November 20 to December 7 is 17 days, and that is your working window to compare, enroll, and confirm. Step one, pull the client's current drug list and preferred pharmacy before the call. Step two, run each medication through Plan Finder at Medicare.gov for the plans you can offer, and note which plans cover each drug. Step three, check whether each doctor is in the plan's network. Step four, if the new plan wins, submit the enrollment well before December 7 rather than on it, so a glitch does not eat your last day. Step five, tell the client the new plan begins January 1, and that the January 1 to March 31 Open Enrollment Period is a fallback only if they are in a Medicare Advantage plan. That is one client, 17 days, and five checks.

What agents get wrong

Most AEP errors come from treating the window as a formality. The first is promising timing the rules do not support, such as telling a client a new plan will fix a problem before January 1. The second is reviewing only the plan the client already has, which skips the question of whether to move between Original Medicare and Medicare Advantage at all. The third is leaving Part D out of the conversation. Medicare.gov publishes late-enrollment penalty information, and a client who drops or lets drug coverage lapse can create a cost that lasts, so never treat a drug plan as optional without checking it. The fourth is waiting until the final week to submit. Late submissions leave no room to correct a wrong doctor, pharmacy, or drug entry. The fifth is assuming the January window is open to everyone. It serves only people already in Medicare Advantage. Each of these costs a client money or access. Build them into your intake.

How to check your own files

Before each review, check the file, not your memory. Pull the client's current plan documents, including the plan's notice of changes for next year, and compare them with what the client has now. Confirm the drug list with dosages and the preferred pharmacy, then run them through Plan Finder at Medicare.gov. List every doctor and facility the client uses and verify each against the network. Check the client's current coverage type: Original Medicare, Medicare Advantage, or a standalone drug plan, because that decides which choices are on the table now and whether a fallback exists from January 1 to March 31. Confirm you are appointed and certified for the plans you intend to discuss. Review CMS Medicare Communications and Marketing Guidelines and the rules at 42 CFR 422.2264 and 423.2264 before you contact anyone, and document the scope of the conversation. Finally, set your own deadline several days before December 7 and add every client to it by name.

What to say, and the one takeaway

Here is the conversation to have with every client. Open with the dates: AEP runs October 15 through December 7, and what they choose takes effect January 1. Then ask three questions: which drugs do you take, which doctors do you see, and which pharmacy do you use. Those answers drive the comparison. Close by confirming what happens next, including the date you will submit and the date their new coverage starts. For outreach, follow the Federal Communications Commission's TCPA guidance before you call or text anyone, and keep your marketing consistent with CMS rules so you never imply a plan is endorsed by Medicare. The takeaway for the whole piece is simple: AEP is a dated window with a January 1 start, so set that expectation first, run the comparison from the client's actual drugs and doctors, and submit early. A client who understands the timing and limits is far less likely to be surprised in January.
