Your Spouse Dies and Medicare Stays — But the Single-Filer Switch Can Raise Your Premium Two Years Later

Losing a spouse can change more than a retiree’s household income.

Losing a spouse doesn’t end your Medicare coverage, but it can quietly change the math used to determine what you pay for it. One potential surprise involves the Medicare IRMAA, the income-related surcharge added to Medicare Part B and Part D premiums for beneficiaries whose income exceeds certain thresholds.
