I do not know because I dont have medicare. i would suggest you asking the question on
www.obesityhelp.com
What I did think but not sure if accurate is that with medicare you have a 6 month monitored diet & then you can be approved/denied for surgery. After that time then you can do you testing which does not take long. You may want to call Medicare & ask them. Because if you do need a 6 mon. diet you will want to start asap.
I have lapband so feel free to ask any questions you may have. Also, look under the Diet/Exercise Buddies for the WLS Diva thread.
