Strain musc/tend peroneal grp at low leg lev, r leg, subs

This code signifies a non-traumatic overstretching or tearing of the muscle fibers and/or tendons of the peroneal muscle group located in the lower right leg. This injury typically results in pain, swelling, and difficulty with ankle movement, particularly eversion.

Use this code for follow-up encounters for a patient who has previously been diagnosed and is receiving ongoing treatment for a strain of the right peroneal muscles and tendons. This includes visits for physical therapy, re-evaluation of symptoms, or medication adjustments during the healing phase.

• Ensure the documentation clearly specifies the right leg and indicates a subsequent encounter for the injury.
• Distinguish this from initial encounters (A) or sequela (S) codes.
• Verify the injury is a strain, not a sprain (ligamentous injury) or a complete rupture.
