How can I qualify for a tummy tuck surgery paid by insurance?

Unfortunately for you insurance does not cover a tummy tuck since it is a cosmetic procedure. Some patients have diseased and infected skin at the lower abdomen and it can be covered by insurance as a procedure known as a "panniculectomy".

 By definition a tummy tuck or Abdominoplasty  is a cosmetic operation and is not covered by any insurance carrier. 
You might however be able to qualify for a panniculectomy which is covered by insurance. The best bet is to look on your carriers website and see what their criteria are for approval for the panniculectomy and see a plastic surgeon in your area that takes your insurance. 

An abdominoplasty is a cosmetic procedure, and not covered by health insurance. Some health insurance plans will cover a panniculectomy, with proper documentation, however, this procedure is different from an abdominoplasty. I recommend setting up a consult with a boards certified plastic surgeon to discuss the difference between these procedures.
