Federal legislation allowing an employee or an employee's dependents to maintain group health insurance coverage through an employer's health insurance plan, at the individual's expense, for up to 18 months in certain circumstances. COBRA coverage may be extended beyond 18 months in certain circumstances. COBRA rules typically apply when an employee loses coverage through loss of employment (except in cases of gross misconduct) or due to a reduction in work hours. COBRA benefits also extend to spouses or other dependents in case of divorce or the death of the employee. Children who are born to, adopted, or placed for adoption with the covered employee while he or she is on COBRA coverage are also entitled to coverage. All companies that have averaged at least 20 full-time employees over the past calendar year must comply with COBRA regulations.
