Here is the Anthem Medical Policy regarding revisions or change to different procedure after complications, hope this helps and hope that you will be approved. It will be a fight I am sure but don't give up.
Repeat surgical procedures for revision or conversion to another surgical procedure (that is also considered medically necessary within this document) for inadequate weight loss, (i.e., unrelated to a surgical complication of a prior procedure) are considered medically necessary when all the following criteria are met:
- The individual continues to meet all the medical necessity criteria for bariatric surgery (see page 1); and
- There is documentation of compliance with the previously prescribed postoperative dietary and exercise program; and
- 2 years following the original surgery, weight loss is less than 50% of pre-operative excess body weight and weight remains at least 30% over ideal body weight (taken from standard tables for adult weight ranges based on height, body frame, gender and age, an example is available from the National Heart Lung and Blood Institute [NHLBI] at: http://www.nhlbi.nih.gov/guidelines/obesity/bmi_tbl.htm.
