Medigap polices are generally not sold to people under 65. There are some states, however, in which individuals under 65 can purchase a Medigap policy. Individuals enrolled in a Medicare Advantage Plan should not be sold a Medigap policy.
It is illegal to sell a Medigap policy to anyone enrolled in a Medicare Advantage (MA) Plan unless that individual is switching to Original Medicare. If you have a MA plan and someone approaches you with the intention of selling you a Medigap policy, obtain that person’s information and report it to your State’s Insurance Department.
If you are enrolled in Original Medicare and have a Medigap policy, switching to a Medicare Advantage (MA) plan does not automatically cancel your Medigap policy. You should call your Medigap insurance company and ask them to cancel your Medigap policy because you have enrolled into a MA plan. Keeping your Medigap policy while enrolled in a MA plan, is of no advantage to you since your Medigap policy cannot be used in conjunction with a MA plan. Keep in mind that once you drop your Medigap policy and enroll in a MA plan, you will not be able to get it back unless you switch back to Original Medicare.
Special rights are granted to you if you join a MA Plan for the first time and are unhappy with it. You have the right to return to Original Medicare and you have the right to purchase a Medigap policy. However, your switch from the MA plan back to Original Medicare must take place within 12 months of your joining the MA plan.
If you had a Medigap policy before you joined the MA plan, you may be able to enroll back into the same policy if the company still offers it. If it is no longer offered, you may purchase a different Medigap policy. Important to know is that the Medigap policy cannot have prescription drug coverage, even if you had it before. In this case, you must purchase a stand-alone Prescription Drug Plan.
