Wiki 19357 Incidental to other cpt

[hallm42]

Aetna insurance is denying my claim, I billed a 19357-50, 19370-50 and 19328-50 and they are saying 19370 and 19328 are incidental to 19357.

First off am I billing correctly and second, has anyone else had this and if so how did you appeal it?

Thank you
