Sprain of tarsal ligament of unspecified foot, init encntr

This code signifies a sprain affecting the ligaments connecting the tarsal bones in the foot, without specifying which particular tarsal ligament or the exact foot involved. It indicates that this is the first time the patient is receiving active treatment for this specific injury.

Use this code when a patient presents with a new, acute sprain of an unidentifiable tarsal ligament, and the medical record does not specify whether it's the left or right foot. This is appropriate for initial evaluations and treatments following the injury.

• Ensure documentation clearly states "sprain" and "tarsal ligament" but lacks laterality.
• Only use the "A" seventh character for the initial encounter for active treatment.
• Avoid if a more specific tarsal ligament (e.g., calcaneonavicular) or foot (left/right) is documented.
