If my spouse has a family HDHP with an HSA, and I lose coverage under my individual HDHP, can I still contribute to my HSA?

If my spouse has a family HDHP with an HSA, and I lose coverage under my individual HDHP, can I still contribute to my HSA?: If you lose HDHP coverage during a tax year, you must prorate the maximum contribution for the number of months you had eligible coverage. You have until the tax filing deadline for that year to make those contributions.
