ICD-10 Code D57.818 – Other sickle-cell disorders with crisis with other specified complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D57.818 – Other sickle-cell disorders with crisis with other specified complication
What it is
This code identifies a sickle-cell disorder with an acute crisis plus another specified complication that is not named elsewhere in the category. Use it when the record clearly supports both the crisis and the additional complication.
Clinical signs
Typical crisis findings may include severe pain, anemia-related symptoms, or other acute sickling features. Clinical features vary; refer to documentation for the specific complication prompting this code.
When to use this code
Use D57.818 when the provider documents a sickle-cell disorder in crisis and also names another specified complication that does not fit a more specific code. You should code the documented complication, not infer it from symptoms alone. If the record is vague, check documentation.
Do not use for
Do not use this code for uncomplicated sickle-cell disease, or when a more specific sickle-cell crisis or complication code is documented. Do not assign it if the additional complication is not clearly stated.
Coding tip
Capture the exact crisis type and the named complication together; if either is unclear, query the provider.
