Contusion of thorax, unspecified, subsequent encounter

This code signifies a bruise or injury to the chest wall, without an open wound, that is being treated or evaluated after the initial encounter. It indicates damage to the soft tissues, such as muscle, fat, and blood vessels, resulting from blunt force trauma to the thoracic region. The specific location of the contusion within the thorax is not documented.

Apply this code when a patient presents for follow-up care, such as wound checks, pain management, or physical therapy, for a previously diagnosed and treated contusion of the chest. This includes scenarios where the patient is returning for re-evaluation of symptoms or complications related to the initial injury.

• Ensure documentation clearly indicates "subsequent encounter" for the contusion.
• If the specific site of the thoracic contusion is known (e.g., breast, rib cage), use a more specific code from the S20.2- series.
• Do not use this code for initial treatment of a new contusion; refer to the "initial encounter" codes.
