Ask Dr. Z

I thought I read something about a change. The patient has known CAD, and the only procedure done is an IVUS of the left main and LAD. "Patient's groin was prepped, and a 5 French sheath was placed and guide advanced. Wire was placed down to the LAD, and IVUS of the left main and LAD was done." I have documentation of the IVUS findings. Catheter as well as sheath were removed. IVUS would be reported with codes 92978 and 92979, but current edits indicate a base code is needed. We don't have a base code. Was there a change so this can be coded, or is there another code that we are to add? Or is the claim going to be denied?
