Help with cpt code 43848

Orignally I had gastric bypass in 2001.I am having a revision done with my doctor using cpt code 43848 .I have regained about 50 lbs. in the last year.Does anyone know what this coding procedure entails.My doctor said he is going in to repair my original surgery.My pouch and stoma is enlarged. My doctor submitted my paper work on Dec 16,2009 and then Bluecross/Blueshield of Tx. requested a  compliant diet history with a prescribed nutrition and exercise program following the original surgery. My doctor office faxed over my diet history I had with weigh****chers from 5-09 to 11-09 and from the time I had been seeing my doctor ,plus my employer has a health program for us to join on line within our company and that was submitted also I have been complying with for the last 2 years.They also ask that my doctor give details of the procedure for the coding of 43848. On my policy code 43848 is covered. My doctor  faxed over the information originally on Dec 22,2009 but they said they never recieved it but as of  Dec 29,2009 it is now posted in their system.(dr. office had to refaxed information. Since this is all they are requesting  I am hopeful it will be approved.What do you think ? Anyone had this revision before?

Hoping you can help me too. Hope you are doing well. I had a 25 year old surgery revised 12/11. BCBS has not paid yet. I know it needs some kind of code besides 43848.  Did you ever get yours resolved.... Seems like ,surely, I not the first person to have had this problem in AL. Maybe someone can help me.......
