Hi there, we had a patient come in that moved here from another state where she recently had MOHS w/ a flap closure. She just came in for a wound check as she was unsure the site was healing properly - it was just fine when our provider looked at it. We are billing 99202 w/ Z08 as primary dx but it is denying as Z08 cannot be used as a primary diagnosis. Is there any diagnosis that I can use as a primary to get this paid? Thanks!
