Sprain of other ligament of unspecified ankle, init encntr

This code signifies a sprain involving a ligament in the ankle other than the common lateral collateral ligaments (anterior talofibular, posterior talofibular, calcaneofibular) or the deltoid ligament, where the specific ligament is not documented. It indicates the initial treatment or evaluation for this injury.

Use this code when documentation confirms an ankle sprain, but the specific ligament involved is not identified, and it's not one of the commonly specified ligaments. This is appropriate for the patient's first visit for this particular injury.

• Ensure the documentation explicitly states "unspecified" or lacks detail regarding the specific ligament sprained.
• Avoid using this code if a more specific ligament (e.g., anterior talofibular, deltoid) is documented; instead, use the appropriate specific sprain code.
• Confirm that this is indeed the initial encounter for the injury; subsequent visits would require a different encounter character.
