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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 01HY includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in the peripheral nerve. These ICD-10-PCS codes are used for inpatient documentation when an implanted or placed device targets a peripheral nerve to provide monitoring, stimulation, or functional support. Accurate coding within the ICD-10-PCS 01HY group is essential for proper inpatient reimbursement, as it captures the specific insertion procedure performed and supports clinical documentation accuracy.

Peripheral Nerve Insertion Procedure Overview

This procedure group covers insertion of nonbiological appliances that monitor, assist, perform, or prevent physiologic function in the peripheral nerve. Procedures target the peripheral nervous system and involve placing devices such as nerve stimulators, monitors, or neuroprosthetic leads into or adjacent to peripheral nerves. Accurate ICD-10-PCS coding of these insertions ensures inpatient records reflect the specific operation and device, which affects case mix and reimbursement.

When to Use

Use these codes when an implanted or placed nonbiological device specifically targets a peripheral nerve for monitoring, stimulation, or functional assistance during an inpatient encounter. Do not use these codes for procedures that revise, remove, or replace such devices; select the appropriate revision or removal code group instead.

Typical Clinical Scenarios

A patient is admitted after a traumatic limb injury with acute neuropathic pain localized to the median nerve distribution that is refractory to conservative management. The surgical team places a neurostimulator lead adjacent to the injured peripheral nerve to provide targeted electrical stimulation for pain control during the inpatient stay and to evaluate efficacy before potential permanent implantation. The procedure is performed using a percutaneous approach under imaging guidance. Typical codes: 01HY3MZ
An adult with long-standing diabetic peripheral neuropathy experiences disabling, chronic paresthesia and motor dysfunction in a specific peripheral nerve distribution. During a planned inpatient admission for device placement, a neurostimulator lead is implanted via an open surgical approach adjacent to the affected peripheral nerve to provide ongoing neuromodulation therapy. The procedure is elective and intended to improve function and reduce neuropathic symptoms. Typical codes: 01HY0MZ
A patient with recurrent focal seizures of peripheral nerve origin undergoes inpatient placement of a monitoring device directly into a peripheral nerve to capture neurophysiologic signals after noninvasive studies were inconclusive. The monitoring device is introduced using a percutaneous endoscopic approach to allow short-term inpatient telemetry and to guide further therapeutic planning. This is performed because precise peripheral nerve monitoring is required to localize the source. Typical codes: 01HY42Z
