Inj muscle and tendon of back wall of thorax, sequela

This code signifies a long-term or late-effect complication arising from a previous injury to the muscles or tendons located in the posterior thoracic wall. These sequelae can manifest as chronic pain, weakness, restricted range of motion, or other persistent functional impairments directly attributable to the initial trauma. The injury itself is no longer acute, but its lasting consequences are being addressed.

Utilize this code when documenting conditions that are residual effects of an old injury to the back muscles or tendons of the chest wall. This includes situations where a patient presents with chronic symptoms such as persistent muscle stiffness, scar tissue formation, or ongoing functional limitations months or years after the initial acute injury has healed. It is appropriate when the current encounter is focused on managing these long-term complications.

• Always assign a secondary code to identify the specific nature of the sequela, if known (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a past injury of the specified anatomical site.
• Do not use for acute or current injuries; this code is exclusively for late effects.
