Injury of blood vessels of thorax (S25) ICD-10-CM

About the S25 Code Range

The ICD-10 code section S25 covers injuries to the blood vessels of the thorax, including arteries and veins such as the thoracic aorta, innominate or subclavian vessels, superior vena cava, pulmonary vessels, intercostal vessels, and other specified thoracic vessels. These codes differentiate by the specific vessel injured, severity (minor or major laceration), and the phase of care (initial, subsequent, or sequela).

This range includes detailed codes for traumatic conditions like traumatic rupture of thoracic aorta, also known by synonyms such as "traumatic tear," "aortocaval fistula," or "dissection of thoracic aorta," specified under codes like S25.00XA. Injuries to the innominate or subclavian arteries and veins are coded with side specificity (right, left, or unspecified) and may include terms such as "injury of right subclavian artery" or "traumatic injury of left brachiocephalic vein." The section also includes injuries to pulmonary blood vessels, intercostal vessels (arteries and veins), and other thoracic vessels such as the azygos or internal mammary vessels. The ICD-10 codes precisely document injury type—unspecified, minor, major, or other specified—and encounter stage to support accurate clinical reporting and billing for thoracic blood vessel trauma.
