Aortic valve debridement and replacement using 23 mm St Jude mechanical valve. (33405)
Aortic valve annulus abscess incision and drainage, debridement with bovine pericardial patch repair. (?)

I would appreciate any feedback on how to bill for the annulus I&D with bovine patch repair. The bovine patch was placed in the soft tissue defect of the commissure in between the right and left coronary sinus.

Thank you
