Blue cross patients are required to wear compression stockings for a three-month timeframe as a conservative measure before treatment can begin. They require that the patient have supervised use over this three-month trial period. This means that the patient most follow up at least one time a month for the three months. During the follow up appointments the stockings will be checked to verify that they are the appropriate size and worn correctly. The patients’ symptoms will also be documented at these follow-ups along with any other problems or complications. After the three-month trial period, all of the documentation will be sent in for authorization and approval.
