Please read & help if you can!!

Hey everyone...okay I am in need of some assistance.  I have IA Medicaid and am trying to get this surgery.  I did EVERYTHING they required in order to get approval and I received a denial letter today stating that I do not meet the age required by Iowa Medicaid Enterprises in order for approval for gastric bypass surgery?  What does this mean?  Anyone heard of this?  I am 25 by the way.  If this was the case, why didnt the insurance dept in my surgeons office let me know this...so that way if I wasnt even going to get approved on that alone..that would have saved a whole lot of time, you know?  Please let me know..any insight on this would be greatly appreciated!
