Unspecified sprain of left thumb, initial encounter

This code signifies an injury to the ligaments of the left thumb, where the specific ligament involved or the exact nature of the sprain (e.g., partial tear, complete tear) is not documented. It indicates that the patient is receiving initial active treatment for this injury.

Use this code when a patient presents with a left thumb sprain, and the medical record lacks detailed information about the specific ligament affected or the severity of the sprain. It is appropriate for the first encounter for treatment of this injury, such as an emergency room visit or initial physician consultation.

• Ensure the documentation clearly specifies the left thumb and that the injury is a sprain, not a fracture or dislocation.
• Confirm that this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• If the specific ligament or severity is later identified, a more specific code should be used for subsequent encounters.
