I am on standard and have been calling OB/GYNs to find out about getting the mirena. A few told me that the patient has to pay for it up front then tricare reimburses you. Now I like having standard and don't mind a copay but I can't afford to front the $750 bill of the mirena even if I will be reimbursed. Is this standard practice or do I need to find a different doctor? Tia!
