ICD-10-PCS Code For Phrenic Nerve: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 01R2 includes procedures performed to replace biological or synthetic material that takes the place and function of all or a portion of the phrenic nerve in the peripheral nervous system. These ICD-10-PCS codes are used for inpatient documentation when a phrenic nerve has been substituted with grafts, conduits, or prosthetic material to restore diaphragmatic innervation. Accurate coding within the ICD-10-PCS 01R2 group is essential for proper inpatient reimbursement, as it captures the specific replacement procedure performed and supports clinical documentation accuracy and appropriate case mix assignment.

Phrenic Nerve Replacement Procedure Overview

Procedures in this ICD-10-PCS code group involve replacing all or part of the phrenic nerve with biological or synthetic material. These operations target the peripheral nervous system and restore or substitute phrenic nerve function. Accurate ICD-10-PCS coding ensures inpatient records reflect the extent of nerve replacement and supports appropriate reimbursement and case mix assignment.

R	Operation	Replacement
2	Body Part	Phrenic Nerve

When to Use

Use a code from this group when the operative intent is to replace the phrenic nerve with a graft or prosthetic material rather than repair, resection, or other actions. These codes are appropriate when documentation clearly indicates replacement as the root operation and specifies the phrenic nerve as the body part.

Typical Clinical Scenarios

A young adult suffers a high-velocity trauma to the neck with brachial plexus and phrenic nerve avulsion resulting in diaphragmatic paralysis and progressive respiratory compromise requiring inpatient stabilization and surgical restoration of diaphragmatic innervation; when intraoperative findings confirm a segmental loss of phrenic nerve continuity and the surgeon replaces the damaged segment with the patient’s own nerve or fascial graft to reestablish function, an open replacement procedure is performed. Typical codes: 01R207Z
An adult with slow-onset unilateral diaphragmatic paralysis from prior cervical tumor resection returns electively for reconstruction after conservative measures fail to improve pulmonary symptoms; during a planned inpatient operation, the surgeon substitutes the diseased portion of the phrenic nerve with a synthetic conduit to restore nerve conduction and improve respiratory mechanics. Typical codes: 01R20JZ
A patient with a prior nerve graft for phrenic nerve injury develops graft degeneration and recurrent hypoventilation, prompting inpatient revision; the operative plan is to remove the failed nonautologous graft and replace it endoscopically with a new nonautologous tissue substitute to reestablish diaphragmatic innervation. Typical codes: 01R24KZ
