Hernia and diastasis detected by physical exam but not in CT-Scan - is this a problem for insurance coverage of hernia repair?

I have been to both a gastro and a board certified plastic surgeon who both felt diastasis recti and a small umbilical hernia. I am also seeing a general surgeon next week ( to coordinate with plastic surgeon to fix hernia and diastasis at same time) I know the diastasis is not covered but that the hernia repair part should be - since the ct scan did not show the hernia is that going to be a problem for insurance coverage or is the physical exam of the doctors enough to give coverage of hernia
