Ask Dr. Z

Patient's surgery included aortic valve replacement (mechanical) and left coronary sinus aortic root annuloplasty.

"During the aortic annulus debridement, it was noted that there was gross amount of purulence that was cultured and negative for any bacteria. It was felt that the best course of action would be to patch this left coronary sinus to help strengthen as a result of the chronic inflammatory nature of the native valve, which had been slightly weakened. Therefore a small patch of autologous pericardium was sewn in place as a patch to the left coronary sinus directly below the left coronary ostia to help strengthen the annulus for eventual valve sutures in this area. The valve annulus was then sized with valve specific sizers."

Is there a specific CPT code I should use for the aortic root annuloplasty, or would this be included with code 33405?
