During Medicare Advantage open enrollment, people can switch plans or move to original Medicare through March 31.
Switching to original Medicare can backfire if Medigap insurers deny coverage using medical underwriting based on health history.
Many switch because MA networks are smaller, prior authorization can be heavy, and some plans have exited areas.
Guaranteed Medigap access exists for limited windows, including initial Part B enrollment, trial rights, and some state rules.
Advocates suggest free SHIP counseling, as underwriting has tightened and drug-history checks increasingly drive decisions.
I’m seeing more people consider leaving Medicare Advantage for original Medicare, but Medigap access can be a hurdle. Underwriting, limited guaranteed windows, and plan exits make counseling and timing especially important.
