About 33240: Single-lead defibrillator generator insertion
Reports insertion of an implantable defibrillator pulse generator connected to an existing single lead, without placing a new lead.
The service places an implantable cardioverter-defibrillator (ICD) pulse generator and connects it to one previously implanted lead. The lead is retained; this code does not describe placing a new defibrillator lead. Electrophysiologists and cardiac surgeons typically perform the procedure in a hospital operating room or electrophysiology setting when the generator is being inserted separately from lead placement.
Report the code when the operative record supports generator insertion with an existing single-lead system, rather than insertion of a complete system or a generator exchange. Documentation should identify the existing lead and describe generator placement and connection. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. For multiple procedures in one session, CMS pays the highest-valued procedure in full and other procedures at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

33240 billing questions
Does this code include placement of a defibrillator lead?
No. It covers generator insertion connected to an existing single lead; it does not describe placing a new lead.
How does this differ from code 33249?
Use 33240 for generator insertion with an existing single lead. Code 33249 describes insertion or replacement of an ICD system with transvenous lead placement.
Is this the code for replacing an existing generator?
No. For an exchange of the generator in a single-lead system, compare code 33262, which describes removal and replacement of the generator.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code; a single generator and its lead are not a bilateral service.
How does the 90-day global period affect postoperative visits?
The global period includes the day-before preoperative visit and related postoperative care for 90 days after surgery.
Is assistant-at-surgery payment available?
No. CMS lists a statutory restriction on assistant-at-surgery payment for this procedure.
