I have HDHP coverage for my family and HSA for the entire 2020. I have Medicare (Plan A only) as secondary insurance for the month of November and December for myself only. It is applicable to me due to a medical condition for the next 36 months, not because of my age.
By selecting "None" in the "Type of HDHP Coverage" for the last two months, it reduced the annual HSA contribution limit. If I continue to have HDHP as a primary and Medicare Plan A as a secondary for the entire 2021, am I going to have $0 HSA contribution limit? Medicare Part A only covers inpatient hospital stays, thus most of the medical cost is still covered by HDHP. With zero HSA contribution limit, I think it will increase tax for next year. Any way to have the HSA contribution limit even with Medicare?
