I am Tricare North, and even though it isn't stated in the policy that a 6-month diet/exercise plan is required, it is definitely required in NC. I am also standard. I spoke with a nurse that handles the authorization packages as well as a lead policy manager at Tricare. I was told they will kick it back denied if there isn't enough medical documentation for failed weight loss attempts, and this is covered with a 6 month plan. I hope that helps some!
