ICD-10 Code D57.813 – Other sickle-cell disorders with cerebral vascular involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D57.813 – Other sickle-cell disorders with cerebral vascular involvement
What it is
This code identifies a sickle-cell disorder complicated by cerebral vascular involvement, meaning the brain’s blood vessels are affected. Use it when documentation links the sickle-cell condition to cerebrovascular disease or related neurologic involvement.
Clinical signs
Clinical features vary; refer to documentation. Findings may include neurologic deficits, stroke, transient ischemic symptoms, or other evidence of cerebral vessel involvement in a patient with a sickle-cell disorder.
When to use this code
Use this code when the provider documents a sickle-cell disorder with cerebral vascular involvement, such as stroke or cerebrovascular complications attributed to the condition. It may also apply when imaging or specialist notes support cerebral vessel disease in the setting of sickle-cell disease. Check documentation for the specific sickle-cell type if stated.
Do not use for
Do not use it for uncomplicated sickle-cell disease without cerebral vascular involvement. Do not assign it when the record only mentions neurologic symptoms without a documented cerebrovascular link; check documentation.
Coding tip
Always code the sickle-cell disorder and the cerebrovascular involvement only when the provider clearly connects them.
