ICD-11 LA90.3 — Peripheral arteriovenous malformations

This is a peripheral, abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is widely known because of its occurrence in the central nervous system, but can appear in any location.

Diagnosis with code LA90.3 contains 6 clarifying diagnoses:

1. LA90.30 — Portal vein-hepatic artery fistula
2. LA90.31 — Arteriovenous malformation of precerebral vessels
3. LA90.32 — Uterine arteriovenous malformations
4. 8B22.40 — Arteriovenous malformation of cerebral vessels
5. LA90.3Y — Other specified peripheral arteriovenous malformations
6. LA90.3Z — Peripheral arteriovenous malformations, unspecified

The diagnosis is coded elsewhere:
