Ask Dr. Z

When performing a procedure such as an A-fib ablation or left atrial appendage closure, would the physician be able to bill separately for an angioplasty of the intra-atrial septum? This is performed to make it easier to cross. Would CPT code 92992 be appropriate? If not, would we be able to append a -22 modifier for the extra time involved for performing this procedure? Sometimes, the physician has to perform this angioplasty twice in one session.
