Were you aware of the hernia prior to surgery? Make sure the hernia repair is not a result of a misguided Lap Band procedure as in my husband's case which resulted in a 2-week delay in having the band placed and a second surgical procedure because he had to wait for the hole in his stomach to heal. Our insurance required a second authorization for the second surgery.
During my procedure, there was also a "hernia" repair involved that was not covered by the insurance because it was not an approved procedure.
