ICD-10 Code D65 – Disseminated intravascular coagulation [defibrination syndrome] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D65 – Disseminated intravascular coagulation [defibrination syndrome]
What it is
D65 identifies disseminated intravascular coagulation, a serious clotting disorder in which abnormal widespread coagulation uses up platelets and clotting factors. It is documented when the condition is present, not merely suspected.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see bleeding, bruising, oozing from puncture sites, or signs of both clotting and bleeding in the setting of an underlying illness.
When to use this code
Use D65 when the provider documents disseminated intravascular coagulation, DIC, or defibrination syndrome. Code it when the diagnosis is confirmed during an acute illness, obstetric complication, infection, trauma, or other documented trigger.
Assign the code only when DIC is clearly stated in the record. If the note describes abnormal coagulation tests without a diagnosis, check documentation before coding.
Do not use for
Do not use D65 for isolated bleeding, thrombocytopenia, or a generic “coagulopathy” without documented DIC. Check documentation if the condition is only suspected.
Coding tip
Link D65 to the documented underlying cause when the record supports it, and verify whether the provider states acute DIC, chronic DIC, or defibrination syndrome.
