Sprain of unspecified ligament of left ankle, init encntr

This code signifies an injury to the left ankle involving a sprain of an unspecified ligament. It indicates the initial presentation of this type of injury, meaning the patient is receiving active treatment for the sprain. The "unspecified" nature means the specific ligament involved, such as the anterior talofibular or deltoid, was not documented.

Apply this code when a patient presents with a left ankle sprain and the provider's documentation does not specify which particular ligament was affected. This is appropriate for the initial visit where the injury is diagnosed and treatment begins, such as in an emergency department or urgent care setting.

• Ensure the documentation explicitly states "left ankle" and that the ligament is "unspecified."
• Verify that this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
• If a specific ligament is identified (e.g., deltoid, calcaneofibular), a more precise code should be used.
