I'm really sorry you have to go through this. I would call your employer and talk to the benefits coordinator and explain that you have a plan that you like etc. Ask if it is possible to continue on Kaiser and have them pay for it. Some of the companies that I deal with will allow employees to keep their own health insurance for just the kind of reasons you state. They then pay the amount that they would pay if the person was on their plan, and the employee has to pay any difference. The disadvantage to this is that when the employer pays for your helath insurance through their plan it is not taxable income to you and any portion that you would pay is usually pre-tax too. When they do it the other way, they usually include the $ in your check, and you get screwed for the taxes.

Also, ask when your companies open enrollment period is. If you really don't want to switch right now, you might be able to stay on Kaiser through COBRA. Ask if you will be eligible to join the PPO during the next open enrollment if you say "no" now. It may be that open enrollment is in a few months. I don't know what your situation is, but it may be worth it to you to pay for Kaiser for a few extra months out of pocket to give you time to find the right Dr on the PPO. Of course, if open enrollment just passed, this may not be viable.

I feel for you because I just went through the whole switch your insurance thing. The company I was with gave me 45 days notice that they were disbanding the group and I would have no coverage as of July 1. I did manage to get coverage, but I haven't met my new PCP, who I picked out of a book and don't know from Adam! Should be interesting.

I hope you find a brilliant Dr!
