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

This code signifies a non-traumatic injury to the muscles and/or tendons located in the posterior thoracic region, commonly known as the back wall of the chest. This type of injury involves overstretching or tearing of these soft tissues, leading to pain, tenderness, and sometimes limited movement. It does not involve bone fractures or dislocations.

Apply this code for patients presenting with an acute strain of the back muscles or tendons in the thoracic area, such as those experienced after heavy lifting, sudden twisting movements, or repetitive stress. This code is appropriate for the initial visit where the injury is first diagnosed and treatment is initiated.

• Ensure documentation clearly specifies the "back wall of thorax" and not other back regions (e.g., lumbar, cervical).
• Verify the encounter is indeed the "initial encounter" for this specific injury. Subsequent encounters will require a different seventh character.
• Distinguish from contusions or sprains; a strain specifically refers to muscle/tendon injury.
