Don't not forget Manhattan (Standard Life and Casualty). Mine has paid me in excess of $32K so far. Just filed another claim today. When you consider the premium is offset by a $600 per RX reimbursement per year.They're close but not quite the same.
STC is more transitional. From hospital to the home. Usually a few weeks.
HHC is more long range. After you get home and can last a year or more.
Most supplemental companies have them. GTL, Aetna and Heartland have them. Humana says they have one but I haven't looked at it.
