Which of these is your situation?
5 situations. Pick the one that matches and it will explain the rule, what it costs, and what you can still do.
- 2027 Medicare Advantage Plan Changes: What to Do Find your current 2026 Medicare Advantage plan, understand your 2027 notice, and see your next step. Includes enrollment dates and a separate 2027 plan catalog.
- Switching From Medicare Advantage Back to Medigap Check your Medigap rights, application dates and drug coverage before leaving Medicare Advantage. Learn what changes when your plan ends or you leave voluntarily.
- Opted Out of Medicare Part B: What It Costs to Get Back In You turned Part B down, or dropped it later, and now you need it. Getting back in usually means waiting until January, months with no coverage in between, and a higher monthly bill for the rest of your life. Here is what that actually costs.
- HSA Contributions After Medicare: The 6-Month Lookback Medicare Part A can start up to six months before you applied, reducing your annual HSA contribution limit. Learn how to compare contributions with that limit and ask about correcting any excess.
- Small Employer: Medicare Should Have Paid First At 65 or older, a small employer plan may expect Medicare to pay first. Learn how to enroll in Part B, ask about backdating, and meet the deadline for old claims.
