Sprain of tibiofibular ligament of right ankle, init encntr

This code signifies a sprain affecting the tibiofibular ligament in the right ankle. This ligament connects the tibia and fibula bones, and a sprain indicates an injury where the fibers of this ligament are stretched or torn. Patients typically experience pain, swelling, and difficulty bearing weight on the affected ankle.

Apply this code for the initial encounter of a patient presenting with a diagnosed sprain of the tibiofibular ligament in their right ankle. This includes new injuries, whether from a sports accident, fall, or other trauma, where the patient is receiving active treatment for the first time.

• Ensure documentation specifies the right ankle and explicitly mentions the tibiofibular ligament.
• The "A" seventh character indicates an initial encounter for active treatment.
• Differentiate from other ankle ligament sprains (e.g., deltoid, calcaneofibular) based on physician documentation.
