Wrist drop, left wrist

This code signifies a condition characterized by the inability to extend the left wrist and fingers, resulting in a dropped or flexed position of the hand. It typically indicates radial nerve palsy or injury affecting the extensor muscles of the wrist.

Apply this code when documentation clearly states "wrist drop" affecting the left wrist. This diagnosis is often supported by neurological examination findings consistent with radial nerve dysfunction, such as weakness in wrist and finger extension.

• Ensure laterality is accurately documented; distinguish between left, right, and bilateral wrist drop.
• Investigate underlying causes (e.g., fracture, compression neuropathy) and code them additionally if documented.
• Do not confuse with general wrist pain or weakness without the specific "drop" presentation.
