MDIPA, Aetna and Kaiser are the best federal plans for ivf, in that order. However, mDIPA will require primary care referrals for things, and Kaiser is extremely restrictive on where else you can go. I am currently on my spouse's non-federal Aetna plan, which covers 90 percent of infertility services but has a infertility cap of $10,000. I will be switching to MDIPA in November during open season.
To the original poster -- ICSi is usually covered, PGD/CGH is never covered by any of these plans. Pre-authorization for me was relatively painless and should be for you as well given your history. Check your lifetime fertility cap before buying meds with Aetna. I bought mine separately because they will eat into your fertility cap. And aetna does jack up the prices of its meds.
Good luck!
