Official Description

Insertion or replacement of pulse generator only, permanent implantable synchronized diaphragmatic stimulation system for augmentation of cardiac function, with connection to existing lead(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 0680T involves the insertion or replacement of a pulse generator as part of a permanent implantable synchronized diaphragmatic stimulation (SDS) system. This advanced medical device is specifically designed to augment cardiac function, particularly in patients suffering from moderate to severe heart failure while maintaining preserved ventricular synchrony. The SDS system operates by stimulating the diaphragm in synchronization with the cardiac cycle, which helps modify chest pressure. This modification facilitates improved filling and emptying of the heart, ultimately enhancing blood flow without placing additional stress on the heart muscle itself. The system comprises two bipolar active fixation leads that are implanted on the underside of the diaphragm, a pulse generator, and programming software. The pulse generator is responsible for sending small electrical shocks to stimulate a targeted area of the diaphragm, ensuring that normal breathing is not affected. A subcutaneous pocket is created in the abdominal area to securely house the pulse generator, which continuously monitors cardiac activity. It is important to note that this code specifically pertains to the insertion or replacement of the pulse generator only, with the connection to existing leads already in place, thereby streamlining the procedure for patients who have previously undergone implantation of the SDS system.

1. Indications

The insertion or replacement of a pulse generator for a permanent implantable synchronized diaphragmatic stimulation (SDS) system is indicated for patients experiencing moderate to severe heart failure with preserved ventricular synchrony. This procedure is particularly beneficial for individuals whose cardiac function can be augmented through diaphragmatic stimulation, thereby improving overall cardiac output and quality of life.

  • Moderate to Severe Heart Failure Patients diagnosed with moderate to severe heart failure may benefit from this procedure as it aids in enhancing cardiac function.
  • Preserved Ventricular Synchrony The procedure is indicated for those with preserved ventricular synchrony, ensuring that the stimulation aligns with the heart's natural rhythm.

2. Procedure

The procedure for the insertion or replacement of the pulse generator involves several critical steps to ensure proper implantation and functionality of the synchronized diaphragmatic stimulation system.

  • Step 1: Preparation The patient is positioned appropriately, and the area of the abdomen where the pulse generator will be implanted is cleaned and sterilized to minimize the risk of infection.
  • Step 2: Incision and Pocket Creation A small incision is made in the abdominal area to create a subcutaneous pocket. This pocket is designed to securely hold the pulse generator, ensuring it is positioned correctly for optimal function.
  • Step 3: Connection to Existing Leads The existing leads, which have been previously implanted on the diaphragm, are carefully connected to the new or replacement pulse generator. This connection is crucial for the system to function effectively.
  • Step 4: Testing the System Once the leads are connected, the pulse generator is tested to confirm that it is functioning properly and that the leads are delivering the appropriate stimulation to the diaphragm.
  • Step 5: Closure After confirming the functionality of the system, the pulse generator is inserted into the newly created pocket. The incision is then closed, ensuring that the generator is securely sutured to the underlying tissue and that the skin pocket is properly closed over the generator.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any signs of complications, such as infection or discomfort at the incision site. Patients may be advised to avoid strenuous activities for a specified period to allow for proper healing. Follow-up appointments are essential to assess the functionality of the SDS system and to make any necessary adjustments to the programming of the pulse generator. Additionally, patients should be educated on signs of potential complications and the importance of adhering to follow-up care to ensure the long-term success of the implanted device.
