Contusion of bilateral back wall of thorax, sequela

This code signifies a bruise or contusion affecting both sides of the posterior chest wall, specifically as a long-term effect or complication of an initial injury. It indicates that the patient is experiencing residual symptoms or conditions directly resulting from a past contusion to this area.

Use this code when documenting a patient presenting with ongoing pain, tenderness, scarring, or other persistent issues on both sides of their back, stemming from a previously sustained blunt force trauma or injury to the thoracic back wall. This applies when the acute phase of the original injury has passed, and the current encounter addresses these lasting effects.

• Requires an additional code to specify the nature of the sequela (e.g., chronic pain, scar formation).
• Ensure documentation clearly links the current bilateral back wall symptoms to a past contusion.
• Do not use for acute injuries; this code is exclusively for sequelae.
