Injury to cutaneous sensory nerve, upper limb

This code signifies damage to a sensory nerve in the upper extremity that primarily affects the skin's sensation. This injury can result in numbness, tingling, or altered sensation in the affected area of the arm, hand, or fingers, without significant motor deficits. It typically involves superficial nerve branches rather than major nerve trunks.

Apply this code when documentation specifies a traumatic injury to a cutaneous sensory nerve of the upper limb, such as from a laceration, contusion, or compression. Supporting documentation should clearly indicate sensory nerve involvement and localize the injury to the upper limb, differentiating it from motor or mixed nerve damage.

• Ensure the documentation explicitly states "sensory nerve" and not a major mixed nerve or motor nerve.
• Verify the injury site is specifically the upper limb (shoulder, arm, forearm, wrist, hand, fingers).
• Consider additional codes for open wounds, fractures, or other associated injuries.
