My BMI....

I'm looking to have this done at Sparrow in Lansing, MI. If you have can you tell me who did it and how many have they done. Any info or questions that I should ask? Did your insurance pay for it?

Has any one had gastric sleeve done at Sparrow Hospital in Lansing MI? I would like to know if your insurance covered it and who did the surgery. Do you know how many of the sleeves they have done? Or any other information you think I might need to know. Thank you in advance for your reply.
