How old must an individual be at a minimum for open enrollment of Medicare Supplement insurance?

Open enrollment for Medicare Supplement insurance typically begins when an individual is enrolled in Medicare Part B, which is primarily available to those who are 65 years or older. However, there are situations where younger individuals, such as those under 65 with certain disabilities, can also qualify for Medicare and thus have access to Medicare Supplement insurance. Because of this provision, there is effectively no minimum age requirement established for open enrollment; it can occur as soon as a person qualifies for Medicare, regardless of their age. This flexibility ensures that individuals who are eligible for Medicare, whether they are 65 or younger, can take advantage of the supplemental coverage options available to them.
