The problem is, if you’ve already picked an advantage plan then getting A supplemental may not be possible if you’ve had it over a year.

Here are the details?

Trial Period Rights: If you are within your first 12 months of joining a Medicare Advantage plan, or if you left a Medigap plan to join MA for the first time, you have special "trial period" rights, making it easy to switch back.
Guaranteed Issue: If your MA plan terminates coverage or you move outside its service area, you get a 63-day "guaranteed issue" window to purchase specific Medigap policies (A, B, C, F, K, or L) without medical questions.
Underwriting Risk: Outside of guaranteed issue periods, companies can refuse to sell you a Medigap policy due to pre-existing conditions. This is common if you are switching simply because you don't like your current MA plan.
Best Time to Switch: The best time to change is during a "guaranteed issue" period, often within 63 days of losing or changing coverage
