ICD-10-CMLaceration with foreign body of right front wall of thorax without penetration into thoracic cavity, initial encounter
This code describes a traumatic injury to the right anterior chest wall characterized by a deep cut or tear of the skin and underlying soft tissues, accompanied by the presence of an embedded foreign object. Importantly, the injury does not extend into the thoracic cavity, indicating no compromise to the lungs or other intrathoracic organs. This is an initial encounter for treatment of the acute injury.
Apply this code for patients presenting with an open wound on the right front of the chest, where a foreign body (e.g., glass, metal shard, wood splinter) is visible or confirmed within the laceration, and clinical assessment or imaging rules out penetration into the chest cavity. This is appropriate for the initial visit where definitive treatment, such as foreign body removal and wound repair, is performed.
