I am a biller in a small Family Practice and we have no coder. We have a rejected claim due to an Excludes 1 diagnosis issue. The diagnoses used were E03.9, R53.83, F43.0, R73.9, E78.5, R68.82 and Z79.899. I've looked each of these up but I don't see where any of them show an Excludes 1 issue with any of the others. I could really use some help, please.
