If you don’t connect with a representative right away, you will be given the option to save your place in line and be called back once a representative is available.

They know their coverage rules best. If you enrolled in a Bronze or Bronze Plus medical coverage level, check out the HSA User's Guide (PDF) for additional contacts during the year.
