Do I really need supplemental insurance (Medigap) with Medicare?
About 41% of Original Medicare beneficiaries had Medicare Supplement Insurance, or Medigap, in 2021, according to a February 2023 report summarizing enrollment data from AHIP, a national health insurance trade association. For the other 59%, Medicare has some “gaps” that could be costly. “There are many gaps in Medicare that a beneficiary has to pay if they don’t have a Medigap,” Kelli Jo Greiner, Minnesota State Health Insurance Assistance Program director, said in an email.
