Sprain of deltoid ligament of left ankle, initial encounter

This diagnosis code signifies a sprain, or stretching/tearing of the ligaments, specifically affecting the deltoid ligament complex located on the medial (inner) side of the left ankle. This injury typically results from an eversion mechanism, where the foot rolls outward. Patients often present with pain, swelling, and tenderness over the medial malleolus.

Use this code for a patient presenting with a newly diagnosed sprain of the deltoid ligament in their left ankle. This applies when the patient is receiving initial active treatment for the injury, such as evaluation, immobilization, or referral for physical therapy. It is appropriate for the first encounter related to this specific injury.

• Ensure documentation clearly specifies the left ankle and the deltoid ligament.
• Verify that the encounter is indeed the "initial encounter" for this specific injury.
• Distinguish from other ankle sprains (e.g., lateral ligaments) and fractures.
