Injury of cutan sensory nerve at forarm lv, unsp arm, init

This code signifies damage to the superficial nerves responsible for sensation in the forearm, without specifying which arm is affected. This injury typically results in numbness, tingling, or altered sensation in the forearm skin, rather than affecting muscle movement.

Apply this code when a patient presents with a new injury to the cutaneous sensory nerves of the forearm, and the specific arm (left or right) is not documented. This is appropriate for initial evaluations of trauma such as lacerations, contusions, or nerve compression that impact the sensory function of the forearm.

• Ensure documentation clearly indicates a sensory nerve injury, not a motor nerve or a deeper nerve plexus.
• Only use this code when the affected arm is truly unspecified in the medical record. If laterality is known, a more specific code should be used.
• The "A" seventh character indicates an initial encounter for the injury; subsequent care would require different seventh characters.
