They pay the cost of the health-insurance premium, if someone has health insurance. We have not yet seen what it will look like. The principle makes sense, but we do not know about income rules, etc. It could change from other areas when it is implemented here.

Social security has two programs.
The Social Security Disability Insurance, SSDI, is disability insurance. Basically what you are doing is gaining access to your old-age pension income early, via an insurance clause. The amount you get reflects what you paid into the system, via the FICA payroll tax. It's not the most effective program available now. We have found more successful ways to assist people.
