The late enrollment penalty is an amount that may be added to a person’s monthly Part D premium. A person enrolled in a Medicare drug plan may owe a late enrollment penalty if he or she goes without Part D or other creditable prescription drug coverage after the end of his or her Initial Enrollment Period for Part D coverage.
It is not required by federal law for insurance companies to sell Medigap policies to people under 65 years of age. Many states, however, have separate laws that require a Medigap option for Medicare-eligible individuals who are under 65. That means that under 65 individuals may or not be able to purchase a Medigap plan depending on which state you live in.
Most states allow seniors to switch Medigap plans at anytime of the year by answering health questions. Washington State, on the other hand, allows you to switch your Medigap to another Medigap without going through medical underwriting. This can also be done all year long and the only exception is Medigap Plan A, which does not offer this chance.
