While it is relatively easy for a Medicare beneficiary to enroll into and disenroll from a Medicare Advantage (MA) plan on an annual basis, there are limited windows of opportunity to join a Medigap plan. This means that people who want to switch from MA to traditional Medicare may not have the option for supplemental coverage they need, which may lock them into MA coverage. In order for Medicare beneficiaries to have true freedom of choice concerning their coverage options, Medigap plan access must be strengthened.
