Official Description

Removal of an implantable, patient-activated cardiac event recorder

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The removal of an implantable, patient-activated cardiac event recorder, as described by CPT® Code 33284, is indicated in specific clinical scenarios. These may include:

  • Device Replacement The patient may require a new device due to malfunction or technological advancements.
  • Resolution of Symptoms The patient may no longer experience the symptoms that warranted the initial implantation of the device.
  • Device Complications The patient may experience complications related to the device, such as infection or discomfort, necessitating its removal.
  • Patient Request The patient may request removal for personal reasons or preference.

2. Procedure

The procedure for removing a patient-activated cardiac event recorder involves several key steps, which are detailed as follows:

  • Incision The physician begins by making an incision in the skin directly over the location of the implanted device. This incision is typically made in the left pectoral region, where the device was originally placed.
  • Device Extraction Once the incision is made, the physician carefully dissects the tissue to access the subcutaneous pocket containing the cardiac event recorder. The device is then gently removed from this pocket, ensuring minimal trauma to the surrounding tissues.
  • Closure of Incision After the device has been successfully extracted, the physician closes the incision in the skin. This is typically done using sutures to ensure proper healing and to minimize the risk of infection.

3. Post-Procedure

Following the removal of the implantable cardiac event recorder, the patient may be monitored for any immediate complications related to the procedure. Instructions regarding wound care and signs of infection are typically provided. The patient may also be advised on activity restrictions to promote healing. Follow-up appointments may be scheduled to assess the surgical site and ensure proper recovery.
