Ask Dr. Z

Is this reported with code 93619 or 93620? "Indication: Persistent atrial flutter with symptoms of congestive heart failure and slow ventricular response. An octapolar catheters and placed in the coronary sinus and quadripolar catheters were placed in the RV and His bundle region. A 20 pole catheter was then placed around the tricuspid annulus and baseline measurements were made revealing an AA interval of 280 ms, and R-R interval 950 ms and HV of 52. Pacing was performed from the coronary sinus and demonstrated a PPI minus TCL interval of approximately 55 ms. Pacing from the right atrium however demonstrated PPI minus TCL of over 200 ms suggesting this was not typical CTI flutter. The cardioversion was then performed to restore sinus rhythm and with further pacing maneuvers, we were able to demonstrate the continued presence of both clockwise and counterclockwise block. Significantly, the patient developed AV Wenkebach at cycle length 710 ms in sinus node recovery times were performed at 500 ms resulting in an SNRT of 3090 ms with a corrected CNS RT of over 1700 ms which was blatantly abnormal."
