Injury of median nerve at forearm level, unsp arm, init

This code signifies a traumatic injury to the median nerve within the forearm, without specifying the exact location or nature of the injury. It indicates the initial presentation of such an injury, affecting either the right or left arm. This nerve damage can lead to sensory deficits, motor weakness, or pain in the hand and fingers innervated by the median nerve.

Apply this code for new patient encounters involving a suspected or confirmed median nerve injury in the forearm due to trauma, where the specific arm (left or right) is not documented. This is appropriate when the documentation indicates a general injury to the median nerve at this level, such as from a laceration, fracture, or crush injury.

• Ensure documentation clearly states "forearm level" for the median nerve injury.
• Only use this code for the initial treatment of the injury; subsequent encounters will require different seventh characters.
• If the laterality (left or right arm) is specified, a more specific code should be chosen.
