What 33240 covers

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.

How to choose

33230ICD generatorExisting dual leads
33230 is the generator-only insertion code for an existing dual-lead system; 33240 is for an existing single lead.
33249Defibrillator implantComplete transvenous system
33249 covers ICD system insertion or replacement with transvenous lead placement. Use 33240 when the existing single lead is retained and only the generator is inserted.
33262Defibrillator exchangeSingle-lead system
33262 describes removal and replacement of a generator in a single-lead system. Code 33240 describes generator insertion, not generator exchange.
33241ICD generator removalGenerator only
33241 describes removal of an ICD pulse generator without insertion of a new generator; 33240 describes generator insertion with an existing single lead.

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.
