Dissection of thoracoabdominal aorta
ICD-10 I71.03 is a billable code used to indicate a diagnosis of dissection of thoracoabdominal aorta.
Dissection of the thoracoabdominal aorta is a serious cardiovascular condition characterized by a tear in the inner layer of the aortic wall, leading to the separation of the layers of the aorta. This condition primarily affects the thoracoabdominal aorta, which is the section of the aorta that runs through the chest and abdomen. Clinical presentation often includes sudden onset of severe chest or back pain, which may be described as a tearing or ripping sensation. Patients may also exhibit signs of shock, such as hypotension and tachycardia, due to compromised blood flow. The disease can progress rapidly, leading to complications such as aortic rupture, organ ischemia, or even death if not promptly diagnosed and treated. Diagnostic considerations include imaging studies such as CT angiography, MRI, or transesophageal echocardiography to confirm the presence and extent of the dissection. Timely intervention is critical, and treatment may involve surgical repair or endovascular techniques depending on the severity and location of the dissection.

I71.03 specifically covers dissection of the thoracoabdominal aorta, which may occur in the context of aortic aneurysms or other vascular diseases. It is crucial to differentiate it from other types of aortic dissections, such as those affecting the ascending or descending aorta.
I71.03 should be used when the dissection specifically involves the thoracoabdominal aorta. If the dissection is limited to the ascending or descending aorta, the appropriate codes I71.01 or I71.02 should be selected instead.
Documentation should include detailed clinical notes describing the patient's symptoms, imaging results confirming the dissection, and any interventions performed. It is essential to document the location and extent of the dissection clearly.
