Anyone have Cigna and got approve to have band removed to sleeve

Hi I've had the lapband for two years now, after a year I have had nothing but problems with it I can no longer get fills because it makes me so nauseated and bad heartburn. I've lost 80 pounds and since about 8 months I've had no fluid in my band I've gained 10 pounds of that back so my doctor says it needs to come out so has any one have an approval from band to sleeve with Cigna? Plus I will have to wait 6 to 8 weeks to have the sleeve done because my doctor doesn't do the revision at the same time, any thoughts would be helpful.. thanks
