Insurance ?- Non Mechanical Failure of Lap Band for Revision to DS

I have decided to proceed with using Dr. K and I have tried searching on the boards and google for anyone who had insurance cover their  revision from Lap Band to DS, but did not have a mechnical failure of their Lap band.  I have medicare and my insurance is BCBS of Oregon, Medadvantage plan and they say they cover revisions as long as it meets medicare's medical necessity and I meet that but I am concerned that they will not approve due to no mechanical failure of the Lap Band.  Any help would be greatly apprecaited.

Thanks!

If they cover revisions and you still meet the original bariatric surgery qualifications, it should work. So, if your BMI is 40+, or 35+ with comorbidities, you qualify. Having a high BMI is a medical necessity.

I was told that BCBS does cover revisions and they follow Medicare's Medical Necsssity guidelines.  I meet all of those, but I just dont feel BCBS will approve that easy.  I hopeing they dont give me issues about no mechanical failure of my Lap Band.  That is the reason I have seen on the boards for people not getting approval.  Time will tell.  Thanks for the adivce.
