Strain of muscle and tendon of front wall of thorax, init

This code signifies a non-traumatic overstretching or tearing of the muscle fibers or tendons located in the anterior chest wall. This injury typically results in localized pain, tenderness, and possibly swelling or bruising in the affected area. It does not involve a fracture or dislocation.

Apply this code for patients presenting with an acute strain of the pectoral muscles, intercostal muscles, or other soft tissues of the chest wall. This is appropriate for the initial visit where the injury is diagnosed and treatment is initiated. Examples include strains from heavy lifting, vigorous coughing, or athletic activities.

• Ensure documentation specifies "strain" and not a contusion or sprain, and clearly indicates the anterior chest wall.
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from rib fractures or other bony injuries, which would be coded separately.
