Which code is correct? Open 27403 or Scope 29882? Operative documentation states access as " A longitudinal incision was made over the lateral aspect of the knee just posterior to the lateral collateral ligament". The inside out technique requires an incision. After which surgeon reports "I then placed the arthroscopy back in the knee" If access to surgical site is through an open incision then the procedure is considered open? The incision did not open to the joint, only provided access to it. The actual bucket-handle tear repair of the lateral meniscus was performed through the scope.
