COBRA (Consolidated Omnibus Budget Reconciliation Act)
COBRA generally requires that group health plans sponsored by employers with 20 or more employees in the prior year offer employees and their families the opportunity for a temporary extension of health coverage (called continuation coverage) in certain instances where coverage under the plan would otherwise end.

Employee Retirement Income Security Act (ERISA)
Most private sector health plans are covered by the ERISA. Among other things, ERISA provides protections for participants and beneficiaries in employee benefit plans (participant rights), including providing access to plan information.

The Department of Labor's Employee Benefits Security Administration (EBSA) is responsible for administering and enforcing the provisions of ERISA.
