Revision needed, Aetna 2nd time around?

Repeat Bariatric Surgery:

Aetna considers medically necessary surgery to correct complications from bariatric surgery, such as obstruction, stricture, erosion, or band slippage.

Aetna considers repeat bariatric surgery medically necessary for members whose initial bariatric surgery was medically necessary (i.e., who met medical necessity criteria for their initial bariatric surgery), and who meet either of the following medical necessity criteria:

1. Conversion to a RYGB or BPD/DS may be considered medically necessary for members who have not had adequate success (defined as loss of more than 50 percent of excess body weight) two years following the primary bariatric surgery procedure and the member has been compliant with a prescribed nutrition and exercise program following the procedure; or

2. Revision of a primary bariatric surgery procedure that has failed due to dilation of the gastric pouch is considered medically necessary if the primary procedure was successful in inducing weight loss prior to the pouch dilation, and the member has been compliant with a prescribed nutrition and exercise program following the procedure.
