CPT® Code 33284

Deleted

The procedure described by CPT® Code 33284 involves the removal of an implantable, patient-activated cardiac event recorder, commonly known as an implantable loop recorder (ILR). This device is designed to monitor and record the heart's rhythm, particularly during episodes of cardiac symptoms such as palpitations, dizziness, or fainting. The ILR is surgically implanted in a subcutaneous pocket in the chest, where it continuously tracks heart activity and allows the patient to activate it manually when symptoms occur. Upon activation, the device captures and stores the heart rhythm for several minutes, providing valuable data for diagnosing cardiac conditions. The recorder can also be programmed to automatically capture events based on preset criteria. The removal procedure, as indicated by CPT® Code 33284, entails making an incision over the previously implanted device, extracting it from the subcutaneous pocket, and subsequently closing the incision. This procedure is essential for patients who no longer require the device or who may need to replace it due to malfunction or other medical reasons.
