ICD-10 Code D57.09 – Hb-SS disease with crisis with other specified complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D57.09 – Hb-SS disease with crisis with other specified complication
What it is
D57.09 identifies sickle cell disease, Hb-SS type, with a crisis and another specified complication that is not named by a more specific code. Use it when the record clearly documents Hb-SS disease plus an additional complication.
Clinical signs
Clinical features vary; refer to documentation. Typical sickle cell crisis findings may include acute pain, anemia-related symptoms, or other crisis-related complications, but the key is the documented “other specified complication.”
When to use this code
Use this code when the provider documents Hb-SS disease with crisis and names a complication that does not fit a more specific sickle cell code. It is appropriate only when the note supports both the crisis and the additional specified complication. Check documentation if the complication is unclear or unspecified.
Do not use for
Do not use D57.09 for Hb-SS disease without crisis, or when a more specific sickle cell complication code is documented. Do not assign it for vague “sickle cell crisis” notes without the qualifying complication.
Coding tip
Code the documented complication as written, and confirm that “other specified complication” is supported when no more specific ICD-10 option applies.
