Help with code 33256 (MAZE)

  1. Default Help with code 33256 (MAZE)
    Medical Coding Books
    This code states 'with use of cardiopulmonary bypass'. However, you are not allowed to code this with codes 33510-33523, and codes 33533-33548. (bypass codes). Ingenix coding tips suggest the procedure should be reported as 33999 (unlisted) when performed with bypass. Why have a code "used with bypass" when you are not allowed to use it? Is there a way around this mess? How do you code a MAZE with bypass? Thanks
