CPT® Code 63685

Insertion or replacement of spinal neurostimulator pulse generator or receiver, requiring pocket creation and connection between electrode array and pulse generator or receiver

The CPT® Code 63685 refers to the procedure involving the insertion or replacement of a spinal neurostimulator pulse generator or receiver. This procedure is essential for patients suffering from intractable, chronic pain, as it utilizes an implantable generator that produces electrical impulses. These impulses are directed to electrodes that have been previously implanted in the spine, facilitating pain relief through spinal cord stimulation (SCS). The pulse generator is responsible for generating these electrical signals, while the receiver functions to accept impulses from an external generator, transmitting them to the electrodes. During the procedure described by code 63685, a surgical incision is made at the site where the pulse generator or receiver will be inserted or replaced. A subcutaneous pocket is created to house the device securely. The electrodes, which have been implanted in a prior procedure, are connected to the newly inserted or replaced generator or receiver, and the system is tested to ensure proper functionality. After confirming that the stimulation parameters are set correctly, the device is placed into the pocket, which is then closed with sutures. This procedure is critical for managing chronic pain and improving the quality of life for patients who do not respond to conventional pain management therapies.
