I77.71 is a billable ICD-10 code used to specify a medical diagnosis of dissection of carotid artery. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Bilateral carotid artery dissection
- Dissection of carotid artery
- Dissection of external carotid artery
- Dissection of extracranial carotid artery
- Dissection of internal carotid artery
- Dissection of intracranial artery
- Dissection of intracranial carotid artery
- Dissection of left carotid artery
- Dissection of right carotid artery
- Arterial Dissection-. a tear within the wall of the artery.
- Significant Arterial Dissection-. a dissection that impairs flow. this includes type c (a persisting contrast medium extravasation) in the presence of ischemia, type d (a spiral filling defect with delayed but complete distal flow), type e (persistent filling defect with delayed antegrade flow) and type f (filling defect with impaired flow and total occlusion).

An aneurysm is a bulge or "ballooning" in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.
Most aneurysms occur in the aorta, the main artery that runs from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke.
Aneurysms can develop and become large before causing any symptoms. Often doctors can stop aneurysms from bursting if they find and treat them early. They use imaging tests to find aneurysms. Often aneurysms are found by chance during tests done for other reasons. Medicines and surgery are the two main treatments for aneurysms.
