But to answer the OP's question....you can have multiple HSA accounts but your total combined annual contributions cannot exceed the contribution limits.

That wasn't exactly the question.

My husband is in the middle of treatment, and is losing Cobra. I have to cover him under a plan that is not my preferred health coverage.

I have had Kaiser for decades, and don't want to change. It is cheaper for me to cover my husband at work, and for me to buy individual coverage.

Is there a conflict with being covered by two high deductible health plans?
