Hi Jessica,
I have no personal knowledge of the Cheneau, but Chris (mamandcrm) has had an amazing result so far with her daughter's Cheneau through Luke, and I recall they had some insurance coverage of the brace.
Hopefully Chris will pop in soon and give you more info. You can also search through the threads for Cheneau and find her old posts about their experience with the brace and insurance. It seems like Luke's office should also be able to give you more info about this.
Good luck!
