These ICD-10-CM diagnosis codes are used to document congenital venous anomalies that affect venous return, may require surgical or interventional management, and capture anatomic detail and clinical complexity.

ICD-10-CM Q26: Congenital Malformations Of Great Veins Overview
This code group represents congenital malformations affecting the major systemic veins, including anomalies of the superior vena cava, inferior vena cava, and their major tributaries. These conditions target the circulatory system and often present in neonatal or pediatric settings but may be identified later in life. Accurate coding matters for appropriate clinical documentation and reimbursement because it captures the anatomic abnormality and potential complexity of care required.
