ICD-10 Code D68.62 – Lupus anticoagulant syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D68.62 – Lupus anticoagulant syndrome
What it is
D68.62 identifies lupus anticoagulant syndrome, a clotting disorder linked to antiphospholipid antibodies. Despite the name, it is associated with thrombosis risk rather than bleeding.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include venous or arterial thrombosis, recurrent pregnancy loss, or laboratory evidence of lupus anticoagulant positivity in the appropriate clinical context.
When to use this code
Use D68.62 when the provider documents lupus anticoagulant syndrome or confirms antiphospholipid-related hypercoagulability. It may apply during evaluation or follow-up when the diagnosis is established and supported by the record. Check documentation if the note only mentions a positive test without a diagnosed syndrome.
Do not use for
Do not use this code for isolated abnormal coagulation tests without a diagnosed syndrome. Also avoid it when another specific coagulation disorder is documented instead.
Coding tip
Code only when the chart clearly links lupus anticoagulant findings to the syndrome, not to a temporary or incidental lab result.
