I'm leaving my job in a few days, and I have significant "in progress" dental expenses.
I haven't received any official COBRA information yet. I'm worried that any appointments after my last day at work will not be covered, and when I elect to continue my dental coverage under COBRA retroactively, the onus will be on me to somehow prove that those expenses were covered (X-rays and forms with doctor's signatures).
How can I avoid these headaches and assure real continuity of coverage? (Please don't say "call the insurer and ask them" -- I am not naive enough to think they are my friends and will give me advice on how to maximize my benefits at their expense)
Is there anything I can do preemptively, while I still have the job, to keep the same insurance plan without interruptions?
(I'm in California, if this is relevant)
