ICD-10 Code D68.311 – Acquired hemophilia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D68.311 – Acquired hemophilia
What it is
D68.311 identifies acquired hemophilia, a rare bleeding disorder caused by autoantibodies that interfere with normal clotting. It is not inherited hemophilia; you code it when documentation specifically states acquired factor VIII inhibitor or acquired hemophilia.
Clinical signs
Patients often present with unexpected bleeding, such as bruising, soft tissue hemorrhage, mucosal bleeding, or prolonged bleeding after procedures. Clinical features vary; refer to documentation, and confirm the diagnosis is acquired rather than congenital.
When to use this code
Use this code when the record clearly documents acquired hemophilia, acquired factor VIII inhibitor, or a similar diagnosis confirmed by the provider. It may also apply when the note describes an autoimmune bleeding disorder with an acquired clotting factor inhibitor. If the chart only says “hemophilia” without clarification, check documentation before coding.
Do not use for
Do not use D68.311 for congenital hemophilia A or B, or for nonspecific bleeding symptoms without a diagnosed inhibitor disorder. Check documentation if the provider has not explicitly identified the condition as acquired hemophilia.
Coding tip
Code the condition only when the provider documents acquired hemophilia or an acquired clotting factor inhibitor, and query if the record is ambiguous.
