Sherald is trying to look up the CPT code for a left arm cyst biopsy. She has found the code, but how can she show that the procedure took place on the left side? Sherald also came across CPT code 32491 (removal of lung, pneumonectomy), but she needs to also code for the repair of a portion of the bronchus. The code has a (+) in front of it; what does this mean?
