Ask Dr. Z

I have 2 coding situations that, no matter what codes I use, there is a zero edit. Both deal with removal and replacement of a device and, at the same time, capping an old lead and implanting a new lead. 1. A BI V ICD was removed and replaced with a new BI V ICD. They also had their old LV lead capped and a new LV lead placed. 2. Old single chamber pacemaker removed and RV lead capped. New single chamber Pacemaker and RV lead implanted. Am I totally missing something or are the codes for PM and ICD missing something? Thank you for your help.
