Can we code 93655 in addition to 93653 when the initial arrhythmia was atrial tachycardia (AT) in right atrium but then an atrial flutter (atypical) was discovered in the left atrium? Technically, this is a different arrhythmia; however, if both were solo, would they both map to the same 93653?


You would report codes 93653 and 93655 for two separate and distinct mechanisms.  Code 93655 would apply for the second ablation regardless whether it is AT or AT flutter.
