I know cpt code 93623 maybe be reported for IV drug infusion for programmed stimulation and pacing prior to and during ablation procedures. I have tried to explain to a physician that this can be billed at the beginning of a procedure. Now my physician injects isuprel at the end of the ablation procedure to determine if any additional arrhythmias can be invoked and wants me to bill 96365- Intravenous infusion, for therapy, prophylaxis, or diagnosis, initial up to 1 hour at the end of the case. Is it appropriate to bill for this at the end of the ablation procedure with this cpt code 96365? thank you
