Can I still make changes to my Medicare coverage for 2023?

Can I still make changes to my Medicare coverage for 2023?

A: Although Medicare open enrollment concluded on December 7, 2022, beneficiaries enrolled in Medicare Advantage have an additional opportunity to change their 2023 coverage during the Medicare Advantage open enrollment period.

This window runs from January 1 to March 31, and during that time, a Medicare Advantage enrollee is allowed to make one plan change: either switching to a different Medicare Advantage plan, or switching to Original Medicare.

In addition to those two enrollment windows, some Americans have other opportunities to enroll or make changes to their coverage:

Special enrollment for those affected by a natural disaster

The federal government allows a special enrollment period for people who live in (or rely on enrollment help from someone who lives in) an area that experiences a FEMA-declared major disaster or emergency.

In general, if, because of the disaster, you were unable to complete your enrollment during the window that was originally available to you (either a regular enrollment window or one specific to you because you experienced a qualifying event), you’ll have additional time to complete your enrollment. Your disaster-related enrollment window will continue for four months after the start of the FEMA-declared emergency period.

Hurricane season overlaps with the Medicare annual election period in the fall, which can sometimes lead to some areas having additional time to enroll after December 7. There are also FEMA-declared disaster areas due to other situations each year, such as wildfires, tornadoes, and floods.

It’s important to understand, however, that a special enrollment period is only allowed if the timing of the disaster prevented you from enrolling during the scheduled enrollment window or special enrollment period. So for example, although Hurricane Ian wreaked havoc in Florida in 2022, the storm struck a few weeks before the start of the Medicare annual election period, and thus did not trigger any widespread special enrollment periods. (It would, however, trigger a special enrollment period for someone who was in their initial enrollment window at that point, or in a special enrollment period triggered by another qualifying life event.)

What is the 5-star special enrollment period?

If there’s a Medicare Advantage or Medicare Part D plan in your area that has earned the government’s 5-star (excellent) rating, you’re allowed to switch onto that plan anytime between December 8 and November 30. This is called the 5-star special enrollment period, and you’re allowed to utilize it one time during that period.

For 2023, there are a total of 62 Medicare contracts that have a five-star rating, down from 87 contracts in 2022. Most are Medicare Advantage plans with integrated Part D coverage, but the list includes three Medicare cost plans and two stand-alone Part D plans.

Who can use the Medicare General Enrollment Period?

From January 1 to March 31 each year, during the General Enrollment Period, people who are eligible for Medicare Parts A and B but not yet enrolled can sign up for coverage. Coverage will take effect the month after you enroll (the effective date use to be July 1, but that changed as of 2023 as a result of the BENES Act). If you didn’t sign up for Part B when you were first eligible and you haven’t had creditable coverage from an employer plan in the meantime, you’ll have to pay an additional premium for your Part B plan, as a late enrollment penalty.

If you sign up for Medicare during the General Enrollment Period, you have the option to use Original Medicare or Medicare Advantage, just like anyone else signing up during their initial enrollment period. Note that if you already had Part A and used the General Enrollment Period to sign up for Part B, you’ll have to wait until the fall open enrollment period to buy a Part D plan. That’s because you were already eligible to enroll in Part D when you had just Part A, so you can’t use the General Enrollment Period to buy Part D. However, if you have to pay a premium for Part A and you’re using the General Enrollment Period to enroll in both Part A and Part B, you can then select a Part D plan when you enroll in Medicare during the general enrollment period.

And once you’re enrolled in Medicare Part B (and at least 65 years old), you’ll have a one-time six-month enrollment window during which Medigap plans in your area are guaranteed issue. In most states, Medigap plans will be medically underwritten if you apply after that six-month window ends.

When can I enroll in a Medicare Special Needs Plan?

If you develop a condition that makes you eligible for a Medicare Special Needs Plan (SNP) and an applicable SNP is available in your area, you can join it at any time, but once you join, your special enrollment period ends.

If I am a dual eligible, when can I make changes to my Medicare coverage?

If you’re covered by both Medicare and Medicaid, you can switch plans at any time during the year. This applies to Medicare Advantage as well as Medicare Part D.

Note that there are SNPs designed for people who are dual-eligible for Medicaid and Medicare, and there are also SNPs for people who are institutionalized.

When can I enroll in a Medigap plan?

You can apply for a Medicare supplemental insurance (Medigap) plan at any time during the year. If you’re within the six-month open enrollment window that begins as soon as you’re at least 65 and enrolled in Medicare Part B, the coverage is guaranteed issue. That is also the case if you’re in a special enrollment period triggered by a qualifying event. (Be aware that not all of the special enrollment periods for Medicare Advantage or Medicare Part D apply to Medigap plans).

You can still apply for a Medigap plan outside of open/special enrollment periods; just be aware that in most states, the carrier will use medical underwriting to determine whether to accept your application, and how much to charge you.

Some states have created annual windows during which enrollees can switch to a different Medigap plan without medical underwriting, but this is the exception rather than the rule; federal law does not grant any sort of annual open enrollment period for Medigap plans (you can click on your state on this map to see how Medigap plans are regulated).
