Will medical insurance cover a Tummy Tuck if there has been muscle damage?

I am sorry about the problem you are experiencing. Sometimes, insurance companies may authorize  exploratory procedures to rule out neuroma as a source of your abdominal wall pain after C-section. I have never had them authorize  tummy tuck surgery. In other words, insurance companies do not consider this operation medically necessary. Sometimes, however insurance companies will cover excision of lower abdominal wall skin/apron;  this operation is called a panniculectomy. Best wishes.

You should be seen by a pain specialist to accurately diagnose your pain.  It is not clear to me how pain after a C-Section would be treated by an abdominoplasty.  If the scar iteslf is causing you pain, then perhaps a more simple scar revision would help.
