    ICD-10-CM Code For Injury Of Nerves At Wrist And Hand Level: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S64 includes traumatic injuries to the nerves at the wrist and hand level, such as lacerations, crush injuries, and avulsions involving sensory and motor branches. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving peripheral nerve damage in the wrist and hand, capturing severity, laterality, and associated complications. Accurate coding within the ICD-10-CM S64 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM S64: Injury Of Nerves At Wrist And Hand Level Overview

    This group represents traumatic injuries to the peripheral nerves at the wrist and hand level, including lacerations, compressions, and avulsions affecting motor and sensory function. It targets the peripheral nervous system of the upper extremity and the specific nerves supplying the wrist, hand, and fingers. Accurate coding matters because it documents the anatomic site and severity, which supports appropriate clinical records and reimbursement processing.

    Typical Clinical Scenarios

    • An adult presents to the emergency department after sustaining a laceration to the volar wrist from broken glass while falling. The patient has immediate numbness and weakness of thumb opposition and decreased sensation over the palmar thumb and index finger, and exam suggests acute median nerve injury at the wrist; urgent wound care and surgical consultation are performed. A diagnosis from this group is assigned to document the acute nerve injury at the wrist level due to the traumatic laceration. Typical codes: S64.10XA, S64.10XD
    • An office patient with a history of repetitive occupational hand use complains of progressive numbness, tingling, and intermittent weakness in the radial three digits and decreased two-point discrimination; conservative treatment failed and electrodiagnostic testing confirms a chronic compression neuropathy of the median nerve at the wrist. A code from this group is used to capture the chronic nerve injury/entrapment at the wrist for ongoing management and possible surgical planning. Typical codes: S64.11XA, S64.11XD
    • An older patient presents for follow-up after a distal radius fracture treated operatively two months ago; they report persistent neuropathic pain and persistent sensory deficit in the ulnar-sided digits with EMG showing nerve injury related to the prior fracture and surgical fixation. A code in this group is used to document the post-traumatic nerve injury at the hand/wrist as a complication of the prior injury and treatment. Typical codes: S64.20XA, S64.20XD
