ICD-10 Code E83.820 – Generalized arterial calcification of infancy with unspecified genetic causality (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.820 – Generalized arterial calcification of infancy with unspecified genetic causality
What it is
E83.820 identifies generalized arterial calcification of infancy when the genetic cause is not specified. Use it for a documented inherited disorder causing abnormal calcium buildup in arteries during infancy.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe arterial calcification in infancy with vascular stiffness, ischemic complications, or heart-related findings, but you should code only what is documented.
When to use this code
Use this code when the record states generalized arterial calcification of infancy and does not name a specific genetic variant or causative mutation. It is appropriate for confirmed diagnoses in newborns or infants when the provider documents unspecified genetic causality.
Do not use for
Do not use this code if the chart identifies a specific genetic cause, because a more precise code may apply. Do not use it for other causes of vascular calcification or for suspected cases without confirmed documentation.
Coding tip
Check the genetic documentation carefully and code the most specific cause available; if the cause is not stated, use the unspecified genetic causality code.
