ICD-10-CM Code For Injury Of Nerves At Ankle And Foot Level: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S94 includes injuries to peripheral nerves located at the ankle and foot, such as lacerations, contusions, crush injuries, and traumatic amputations affecting nerve structures. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving nerve damage at the distal lower extremity, capturing severity, laterality, and associated soft tissue or bony injury when present. Accurate coding within the ICD-10-CM S94 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM S94: Injury Of Nerves At Ankle And Foot Level Overview

This group includes traumatic and nontraumatic injuries to peripheral nerves at the ankle and foot level, affecting sensory and motor function in the distal lower extremity. It targets peripheral nervous system injuries associated with ankle and foot trauma, entrapment, or iatrogenic causes. Accurate coding supports appropriate payment and reflects clinical severity for care planning and reimbursement.

When to Use

Use a code from this group when clinical documentation identifies a nerve injury localized to the ankle or foot, including documented sensory or motor deficits attributable to trauma or iatrogenic causes. Select codes that specify laterality, encounter type, and any associated fractures, dislocations, or soft tissue injuries to accurately reflect the clinical scenario.

Typical Clinical Scenarios

A middle-aged patient presents to the emergency department after a household fall in which their lateral ankle was forcefully twisted and they report immediate burning pain, numbness, and tingling radiating to the dorsum of the foot. Physical exam reveals sensory loss in the superficial peroneal nerve distribution and focal tenderness over the lateral ankle; imaging excludes fracture. A traumatic nerve injury at the ankle/foot level is documented and an acute external cause code from this group is assigned. Typical codes: S94.11XA, S94.11XD
An elderly patient with a history of peripheral neuropathy and a chronic diabetic foot ulcer develops progressive worsening localized foot numbness and neuropathic pain after repeated debridements and local tissue trauma; the neuropathic signs are persistent and interfere with rehabilitation. The clinician documents an iatrogenic or chronic injury to a nerve at the ankle/foot level as a complication of repetitive procedures and chronic tissue breakdown, so a subsequent or sequela code from this group is used. Typical codes: S94.12XS, S94.12XD
A young athlete presents to outpatient orthopedics several weeks after an ankle laceration from a glass injury sustained during competition; they report ongoing focal numbness on the plantar surface and motor weakness with toe flexion. Because this is a delayed presentation seeking evaluation for nerve dysfunction related to the prior injury (non-acute follow-up), a sequela or encounter for follow-up nerve injury code from the group is selected to capture the residual impairment. Typical codes: S94.90XS, S94.90XD
