If my wife is part of my HDHP and I have HSA which includes her, is the HDHP considered a Family or Single plan? Does 1-A on form 1095-C mean anything?

The language for the 1095-C 1-A code is a little confusing, but it sounds like it is coverage for both myself and any dependents and spouse. So does this mean I have HDHP for family?
