ICD-10-CM Code M31.4
Aortic arch syndrome [Takayasu]

M31.4 is a billable ICD code used to specify a diagnosis of aortic arch syndrome [Takayasu]. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code M314 is used to code Takayasu's arteritis

Takayasu's disease (also known as "aortic arch syndrome", "nonspecific aortoarteritis" and the "pulseless disease":841) is a form of large vessel granulomatous vasculitis with massive intimal fibrosis and vascular narrowing, affecting often young or middle-aged women of Asian descent. It mainly affects the aorta (the main blood vessel leaving the heart) and its branches, as well as the pulmonary arteries. Females are about 8–9 times more likely to be affected than males. Those with the disease often notice symptoms between 15 and 30 years of age. In the Western world, atherosclerosis is a more frequent cause of obstruction of the aortic arch vessels than Takayasu's arteritis. Takayasu's arteritis is similar to other forms of vasculitis, including giant cell arteritis which typically affects older individuals. Due to obstruction of the main branches of the aorta, including the left common carotid artery, the brachiocephalic artery, and the left subclavian artery, Takayasu's arteritis can present as pulseless upper extremities (arms, hands, and wrists with weak or absent pulses on the physical examination) which may be why it is also commonly referred to as the "pulseless disease". Involvement of renal arteries may lead to presentation as renovascular hypertension.

Takayasu's disease (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 446.7 was previously used, M31.4 is the appropriate modern ICD10 code.
