Dissection of aortic arch
ICD-10 I71.011 is a billable code used to indicate a diagnosis of dissection of aortic arch.
Dissection of the aortic arch is a serious cardiovascular condition characterized by a tear in the inner layer of the aorta, leading to separation of the layers of the aortic wall. This condition typically presents with sudden, severe chest pain that may radiate to the back, often described as a 'tearing' sensation. The aortic arch, which is the section of the aorta that curves between the ascending and descending aorta, is particularly vulnerable to dissections. Risk factors include hypertension, connective tissue disorders, and a history of cardiovascular disease. Disease progression can lead to life-threatening complications such as aortic rupture, organ ischemia, or stroke due to compromised blood flow. Diagnosis is primarily through imaging studies such as CT angiography or MRI, which can visualize the dissection and assess its extent. Early recognition and intervention are critical to improving outcomes, as timely surgical or medical management can significantly reduce mortality rates associated with this condition.

I71.011 specifically covers dissection of the aortic arch, which may occur in the context of aortic dissection syndromes, including those associated with Marfan syndrome or other connective tissue disorders.
I71.011 should be used when the dissection specifically involves the aortic arch, as opposed to the ascending or descending aorta, which are covered by different codes (I71.01 and I71.02).
Documentation should include detailed clinical notes describing the patient's symptoms, imaging results confirming the dissection, and any relevant medical history that supports the diagnosis.
