Congratulations!!! Now as soon as you get your DEERs letter? get in contact with the DHA (Defense Health Agency best number:
703.681.1770) and start the process of getting your Timely Filing Waivers in for retrograde Tricare benefits.
Next (as in your next call, do not wait on this step) get in contact with any medical insurance companies you or your spouse/child had and get all EOBs from the time your backdated to now.
Start a file for each family member. Put each EOB in order of date of service (DOS). Your going to have to file these claims, but you need to get that TFW first, otherwise they will all get turned down. Now, as of now, I do not know if they back pay premiums, however they should backpay co-payments. That includes Pharmacy, so if youre like me and went to the same one? Go to there and get whatever list they can give you. That is another claim.
Congrats again and good luck. Feel free to drop me a line if you run into a wall on the Tricare spectrum.
