Truth :
Medicare Part B is permanent once you are eligible, but you can lose it if you stop paying your premium or meet certain other conditions. Most people pay 202.90/month for part B in 2026(or more if the income is above the threshold).
After three delinquent notices, Medicare will terminate your coverage if you do not pay the past-due amount. If your balance exceeds $10 past due after the third notice, there is no protection.
Tip/Trick:
If you miss payment, you get a grace period (about 90 days) to catch up. So, contact your local Social Security office as soon as possible. Reenrolling after termination usually happens during General Enrollment but comes with late enrollment penalties.
For Part B, this means a 10% increase in your premium for each full year you delayed, lasting as long as you have coverage. Part D penalties add 1% of the national average premium per month without creditable coverage rounded to the nearest ten cents.
