Injury of other nerves at forarm lv, unspecified arm, init

This code signifies damage to any nerve in the forearm, excluding the median, ulnar, or radial nerves, when the specific arm (left or right) is not documented. It indicates the initial presentation of such an injury.

Apply this code for patients presenting with nerve damage symptoms in the forearm, such as paresthesia, weakness, or pain, where diagnostic testing or clinical examination points to a nerve other than the major three, and the affected side is not specified. This is appropriate for the initial evaluation and treatment of the injury.

• Ensure documentation clearly states "unspecified arm" if laterality is unknown.
• Avoid using this code if the median, ulnar, or radial nerve is specifically identified as injured; use more specific codes for those.
• Confirm this is the patient's first encounter for this particular injury. Subsequent encounters will require a different seventh character.
