Strain of unsp musc/tend at lower leg level, left leg, subs

This code signifies a non-traumatic injury to the muscles and/or tendons in the lower portion of the left leg, such as the calf or shin, where the specific muscle or tendon involved is not documented. It indicates that the patient is receiving follow-up care for this strain after the initial treatment phase.

This code is appropriate for subsequent encounters when a patient is being seen for ongoing management, rehabilitation, or evaluation of a previously diagnosed, unspecified muscle or tendon strain in their left lower leg. This includes visits for physical therapy, re-evaluation of symptoms, or monitoring of recovery progress.

• Ensure documentation specifies "left leg" and that the encounter is not the initial treatment for the injury.
• Only use this code when the specific muscle or tendon involved in the strain is not identified in the medical record.
• Pair with an external cause code (V00-Y99) if the cause of the strain is known and documented.
