CPT Code 33221 | Description & Clinical Information

CPT 33221 describes the placement of a new pacemaker pulse generator in a subcutaneous pocket in front of the chest by the provider primarily for the artificial regulation of heart beats in patients with arrhythmia, who have a lead in at least three chambers of the heart.

Official Description

The CPT book defines CPT code 33221 as: “Insertion of pacemaker pulse generator only; with existing multiple leads”.

Billing Guidelines

Reporting of CPT codes 33212, 33213, and 33221 should not be done together with CPT codes 33216 and 33217.

When removing and replacing a pacemaker pulse generator, it is not appropriate to report 33212, 33213, 33221, and 33233 together. Instead, use 33227-33229 as appropriate for pulse generator replacement.

If both the insertion of a generator and epicardial lead placement are done, it is necessary to report CPT codes 33202, 33203 along with 33212, 33213, and 33221.

Clinical Information

The procedure described by CPT code 33221 is used in patients who require a multiple lead system implanted for their cardiac condition. The provider must ensure the patient is appropriately prepped and under anesthesia before starting the procedure.

The first step is to create an incision on the skin in the subclavicular region, extending to the subpectoral region. This allows for access to the pectoralis fascia, which is the sheath covering the muscle in front of the chest, or just below the pectoral muscle. A subcutaneous pocket is then created to house the device.

Next, the provider carefully frees the ends of the existing leads from the fibrous adhesions surrounding them. It is crucial to protect the leads from any damage during this process. The pocket is irrigated with saline to ensure cleanliness before placing the new generator for the multiple lead system into the pocket.

The existing lead is tested for proper functionality and attached to the new pulse generator. Hemostasis, which is the stoppage of bleeding, is achieved before closing the skin pocket with sutures. Alternatively, staples or tissue adhesive may be used to close the pocket.

Finally, the device is programmed for functionality. It is crucial to ensure proper programming to achieve the desired outcomes for the patient.

The procedure outlined in CPT code 33221 requires a high level of skill and precision from the provider. There are potential risks associated with the procedure, including bleeding, infection, and damage to the leads. However, when performed correctly, the procedure has a high success rate and can significantly improve the quality of life for patients with cardiac conditions.

It is essential for patients to understand the procedure, including the risks and benefits. Patients should communicate with their provider about any concerns they may have before undergoing the procedure. It is also crucial to follow post-procedure care instructions to ensure successful outcomes.

In conclusion, CPT code 33221 outlines a procedure used in patients who require a multiple lead system implanted for their cardiac condition. The provider must use a high level of skill and precision to ensure successful outcomes. Patients should communicate with their provider about any concerns and follow post-procedure care instructions for the best results.
