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

This diagnosis code indicates a non-traumatic injury to the muscles or tendons located in the anterior chest wall, such as the pectoralis muscles or intercostal muscles. It specifically refers to a strain, which is a stretching or tearing of these soft tissues.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed strain of the front wall of the thorax. This includes subsequent office visits, physical therapy sessions, or other treatments related to the healing and recovery phase of the injury.

• Ensure documentation clearly states "subsequent encounter" or indicates ongoing treatment for the initial injury.
• Verify the injury is a strain and not a sprain, contusion, or fracture.
• Confirm the anatomical location is specifically the front wall of the thorax.
