ICD-10-PCS Code for Accessory Nerve: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 00SR includes procedures performed to reposition structures in the accessory nerve within the central nervous system and cranial nerves. These ICD-10-PCS codes are used for inpatient documentation when a clinician repositions all or a portion of the accessory nerve to its normal or another suitable location due to malposition or injury. Accurate coding within the ICD-10-PCS 00SR group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Accessory Nerve Reposition Procedure Overview

Procedures in this group involve repositioning all or a portion of the accessory nerve within the central nervous system and cranial nerves body system to its normal or another suitable location. These interventions correct displacement or malposition of the accessory nerve to restore function or relieve symptoms. Accurate ICD-10-PCS coding of these procedures ensures proper inpatient documentation and supports appropriate reimbursement.

When to Use

Use a code from this group when a surgical or procedural intervention repositions the accessory nerve because of displacement, injury, or other clinical indications requiring relocation. These codes apply when the primary operative action is moving the accessory nerve to its normal anatomical position or another suitable location.

Typical Clinical Scenarios

An adult presents after a traumatic neck injury from a motor vehicle collision with shoulder droop and weakness of trapezius and sternocleidomastoid function; imaging and intraoperative findings show the accessory nerve displaced or entrapped by scar and bone fragments, necessitating surgical repositioning to restore alignment and prevent progressive denervation. This is treated as an acute inpatient surgical repair with open exposure to mobilize and move the nerve back to its anatomical location. Typical codes: 00SR0ZZ
A middle-aged patient with chronic iatrogenic malposition of the accessory nerve following prior cervical or posterior triangle surgery presents electively with persistent shoulder dysfunction and pain; planned operative intervention involves percutaneous or targeted release and repositioning of the nerve to a more suitable location to improve function. This is managed as an elective inpatient procedure when direct repositioning cannot be accomplished in the outpatient setting. Typical codes: 00SR3ZZ, 00SR0ZZ
A patient develops progressive fibrosis and tethering of the accessory nerve weeks to months after radiation therapy for a head and neck malignancy, resulting in restricted neck motion and progressive denervation; the inpatient procedure addresses the complication by freeing and repositioning the affected segment of the accessory nerve, often using minimally invasive endoscopic assistance to reduce additional tissue trauma. Typical codes: 00SR4ZZ, 00SR3ZZ
