CPT® Code 61885

Insertion or replacement of cranial neurostimulator pulse generator or receiver, direct or inductive coupling; with connection to a single electrode array

The procedure described by CPT® Code 61885 involves the insertion or replacement of a cranial neurostimulator pulse generator or receiver, utilizing either direct or inductive coupling methods. This procedure is specifically performed with the connection to a single electrode array. In simpler terms, a cranial neurostimulator is a device implanted in the body to deliver electrical impulses to specific areas of the brain, which can help manage various neurological conditions. The process begins with making an incision in the anterior chest, just below the clavicle, allowing access to the subcutaneous tissue where a pocket is created for the device. If the procedure is a replacement, the existing device is accessed through an incision made over it, and the device is carefully removed before a new one is inserted. The new pulse generator or receiver is then connected to the cranial electrode wire(s), which are responsible for transmitting the electrical impulses. After the device is properly positioned and connected, it is programmed to ensure it functions correctly, and the incision is closed in layers, often using sutures or staples. This procedure is critical for patients requiring neurostimulation therapy, and it is essential to follow the specific coding guidelines to ensure accurate billing and reimbursement.
