Sprain of chondrosternal joint, initial encounter

This code signifies a sprain, or ligamentous injury, affecting the joint between a rib cartilage and the sternum. It indicates the initial episode of care for this specific type of chest wall injury.

Apply this code when a patient presents with pain and tenderness localized to a chondrosternal joint due to a sprain, often following trauma, sudden movement, or strenuous activity. This is appropriate for the first time the patient is being treated for this particular injury.

• Ensure documentation clearly specifies a sprain of the chondrosternal joint, not a fracture or dislocation.
• Confirm the "A" seventh character is appropriate for the initial encounter for this injury.
• Distinguish from costochondritis, which is an inflammatory condition rather than a sprain.
