Tricare and the DS
Tricare only currently covers RNY. They do not cover the DS because it is still deemed by most insurance companies as being "experimental" and most insurances fear that they will have to pay for complications from DS that are associated with the greater malabsorbtion that occurs with it. I have attached a link for the Champus/Tricare policies regarding WLS, I hope it answers your questions!
