Open Enrollment Explained

The Medicare Open Enrollment Period (OEP) is an annual period (October 15 through December 7) when current Medicare users can choose to re-evaluate part of their Medicare coverage (their Medicare Advantage/Part C and/or Part D plan) and compare it against all the other plans on the market. People can choose to add, drop or switch a Medicare Advantage and/or Part D plans.

To get a better understanding of OED try taking the Medicare assessment, which provides free professional advice about Medicare from a licensed advisor who meets the NCOA's Standards of Excellence.

During the OEP the following can occur:

  • Anyone who has (or is signing up for) Medicare Parts A or B can join or drop a Part D prescription drug plan.
  • Anyone with Original Medicare (Parts A & B) can switch to a Medicare Advantage plan.
  • Anyone with Medicare Advantage can drop it and switch back to just Original Medicare (Parts A & B).
  • Anyone with Medicare Advantage can switch to a new Medicare Advantage plan.
  • Anyone with a Part D prescription drug plan can switch to a new Part D prescription drug plan.

Re-evaluating Medicare Coverage During Open Enrollment

Each year, insurance companies can make changes to Medicare plans that can impact out-of-pocket costs— monthly premiums, deductibles, drug costs, and provider or pharmacy “networks.” A network is a list of doctors, hospitals, or pharmacies that negotiate prices with insurance companies. They can also make changes to plan’s “formulary” (list of covered drugs).

Given these yearly changes, it is a good idea to re-evaluate your current Medicare plan each year to make sure it still meets your needs. Below are some additional benefits of re-evaluating coverage during Open Enrollment:

  1. Switching to a prescipription drug plan that better meets your individual needs can reduce out of pocket costs.
  2. Evaluate your plan to make sure that your doctor(s) remain in-network in the upcoming calendar year. If your doctor is no longer considered in-network, you will likely save money by switching plans to make sure your doctors remain in-network.
  3. Find a higher quality plan. Plans with a 5-star rating are considered high quality. If you are enrolled in a plan that is less than 3-stars, consider using OEP to switch.
