AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2016 Issue 4; ICD-10-CM NEW/REVISED CODES
Arterial Tortuosity Syndrome
A unique code has been created to identify arterial tortuosity syndrome (Q87.82). Arterial tortuosity syndrome (ATS) is an uncommon autosomal recessive connective tissue disorder characterized by tortuosity, elongation and stenosis, of large and medium sized arteries. Tortuosity arises from the abnormal elongation of the arteries, particularly tortuosity of the vessels carrying blood from the heart to the arteries. Other blood vessel abnormalities include constriction, stenosis, aneurysms, and enlarged clusters of vessels underneath the skin. Complications resulting from ATS can be life-threatening. Rupture or dissection of an aneurysm can result in massive blood loss. Blockage of blood flow to...

Article Overview
This article covers arterial tortuosity syndrome as a rare connective tissue disorder and notes the introduction of a specific ICD-10-CM diagnosis code. It is relevant to coders, clinicians, and researchers who need to understand the condition at a high level, its major systemic features, and why the new code matters for studying and tracking the disorder. The article also includes a brief clinical scenario illustrating the diagnosis context.
Why This Topic Matters
The article highlights a newly available diagnosis code for a rare condition, supporting more consistent documentation, research, and future guidance development without requiring broad use of nonspecific coding options.
