Injury of tibial nerve at lower leg level, left leg, subs

This code signifies a non-traumatic injury to the tibial nerve in the lower portion of the left leg. This injury affects the nerve responsible for sensation and motor function to the calf muscles and sole of the foot. It indicates a stage of care following the initial treatment of the injury.

This code is appropriate for encounters where a patient is receiving ongoing care for a previously diagnosed injury to the left tibial nerve at the lower leg level. This includes follow-up visits, rehabilitation sessions, or management of complications arising from the initial injury. It should be used when the patient is no longer in the acute phase of treatment.

• Ensure documentation specifies the left leg and the lower leg level of the tibial nerve injury.
• Verify the encounter is for subsequent care, not the initial treatment or sequelae.
• Look for documentation of the cause of the injury to potentially add an external cause code.
