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

This code signifies a follow-up encounter for an injury to the median nerve within the forearm, where the specific arm affected is not documented. This type of injury can result in sensory deficits, motor weakness, or pain in the hand and fingers innervated by the median nerve.

Apply this code when a patient presents for ongoing treatment, rehabilitation, or follow-up care related to a previously diagnosed median nerve injury in the forearm. This is appropriate when the initial injury occurred, and the current visit is not for the initial acute treatment.

• Ensure documentation clearly indicates a subsequent encounter, not an initial treatment.
• Only use this code when the affected arm (left or right) is truly unspecified in the medical record.
• Always look for more specific codes if the laterality of the injury is documented.
