Your decision will probably depend on an assessment of current and future healthcare requirements vs. cost. With most Fortune 500 companies if that is the case here, you have the option to continue your health coverage under CORBA for 18 months. Assumming that your health history has been good, the cost will generally be higher than you would pay if you seek other options via www.ehealthinsurance.com
for instance; however, with CORBA, your coverage is as good as the group plan that currently covers you. In addition, if you continue with CORBA then you have the option under HIPPA to convert your group coverage to an individual coverage at the end of 18 months. This is desirable if you're concern with potential health problems or are dealing with pre-existing conditions.
So in general, if you're in poor health or concern about potential health conditions, check into CORBA and policy conversion after CORBA termination. If not, then shop around for HSA or lower premium options.
