I need help coding a valve repair. I seem to have a problem understanding the annuloplasty with ring procedure. The procedure, as listed in the operative report is 1) tricuspid valve repair (Alfieri); 2) tricuspid valve annuloplasty with 33mm duran ring. I looked to repair tricuspud valve, and see 33464 whic includes the annulus ring. Should there be 2 codes billed for this procedure, or is the one code, 33464 the only one I should use?
