After reviewing COBRA enrollees acquired from merger of two companies, discovered the following issue: employee terminated on 06/01/07 and elected COBRA health and dental for himself and spouse, employee enrolled in Medicare coverage on 10/01/07 and continued family dental coverage, spouse remained on single health coverage. As of today's date, both are still enrolled in their coverage elected at that time, employee on family dental and spouse on single health. I believe that both should have had their elected coverage end on 12/01/08. What is the best route to take in correcting this? Any guidance would be much appreciated.
