Medicare Premium Increase

Apparently, Medicare increased it’s premiums for next year. I only found out after received a billing statement for January 2021. For December, I paid $462.70 for Part B. That has increased to $504.90. Since my work insurance won’t pay for dialysis anymore, I have to continue to pay for Medicare. At this point, I believe Medicare will pay 80% of transplant costs, and Blue Shield will pick up the remaining 20%, hopefully. Because I sold some stock this year, and the proceeds go on my W2 statement, my premiums will likely increase again to the highest tier right after I file my taxes.
