Connecticut Medigap notes

Connecticut requires Medigap insurers to offer guaranteed issue year-round, which is broader than most states.

Outside of guaranteed issue periods, most Medigap insurers can use medical underwriting. Check whether Connecticut offers a birthday rule or anniversary window before assuming you can switch plans freely.
