Sprain of calcaneofibular ligament of right ankle, init

This code signifies an injury to the calcaneofibular ligament, a key stabilizing structure on the outer side of the right ankle. This type of sprain typically results from an inversion injury, where the foot rolls inward, stretching or tearing the ligament. Patients often present with pain, swelling, and difficulty bearing weight on the affected ankle.

Apply this code when documenting an acute sprain of the calcaneofibular ligament in the right ankle, specifically for the initial evaluation and treatment of the injury. This is appropriate for new injuries, not for follow-up care or chronic conditions. It is used when the patient is first seen for this specific sprain.

• Ensure documentation clearly specifies the right ankle and the calcaneofibular ligament.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from other ankle ligament sprains (e.g., anterior talofibular ligament) as they have separate codes.
