I am on Tricare standard but I believe it works the same for standard & prime. I am currently on the 3 month medically supervised diet program, 2 months in. I am just over a 40 BMI and my comorbidities are not on the list but the doc says they count for Tricare. Mine are GERD, osteoarthritis in my back and a hiatal hernia. I will be having my final doc appointment in October and hopefully scheduling my surgery soon after. Your doc will go over all of the comorbidities etc with you, but you will likely need to have the 3 months supervised diet, psych eval, you will need to attend a support group meeting and a lot of med testing as well. You will have to have 1 comorbidity if you are BMI of 35-39.9 and if you are 40.0 and up there are no required comorbidities.
