2025 ICD-10-CM code J94.2

Hemothorax.

When a hemothorax is caused by trauma, it is important to also code the underlying injury. If both air and blood are present in the pleural cavity (hemopneumothorax), code J94.2 should be used.

Medical necessity for treatment of hemothorax is established by the presence of symptoms, the amount of blood in the pleural space, and the impact on respiratory function.A large hemothorax can compromise breathing and lead to respiratory distress, requiring intervention to drain the blood and restore lung function.A smaller hemothorax might only require monitoring and supportive care.

Diagnosis and treatment of hemothorax typically falls under the purview of pulmonologists, trauma surgeons, or thoracic surgeons, depending on the cause and severity.

In simple words: Hemothorax means blood has collected in the space between your lungs and chest wall.

Hemothorax is an accumulation of blood within the pleural cavity, the space between the lung and the chest wall.

Example 1: A 25-year-old male presents to the emergency room following a motor vehicle accident with blunt chest trauma. Imaging reveals a hemothorax., A 60-year-old female with lung cancer develops a spontaneous hemothorax due to pleural invasion by the tumor., A 30-year-old female undergoes a thoracentesis for a pleural effusion. The procedure is complicated by bleeding, resulting in a hemothorax.

Documentation should include the cause of the hemothorax (traumatic, spontaneous, iatrogenic), the amount of blood accumulated, associated symptoms (chest pain, shortness of breath), treatment provided (chest tube insertion, surgery), and any complications.
