What This Code Means

Sickle cell disease with an acute crisis and a complication other than splenic sequestration, stroke, or hand-foot syndrome, such as acute chest syndrome or kidney problems.

Coding Tips

• •Use this code when crisis is documented with complications not covered by D57.02, D57.03, or D57.04
• •Clearly document the specific complication (acute chest syndrome, renal infarction, etc.) in the medical record

Clinical Significance

This code captures Hemoglobin SS disease crises with specified complications that do not fall into the acute chest syndrome, splenic sequestration, cerebral vascular involvement, or dactylitis categories. These may include priapism, hepatic sequestration, aplastic crisis (often triggered by parvovirus B19), renal complications, or other organ-specific vaso-occlusive events. Each of these complications carries significant morbidity and may require specialized management.

Documentation Requirements

• ✓Documentation must confirm Hemoglobin SS genotype and identify the specific crisis complication present.
• ✓The provider should clearly describe the complication type (e.g., priapism, hepatic sequestration, aplastic crisis, acute kidney injury), supporting clinical findings, laboratory results, imaging if applicable, and treatment administered.
• ✓Record the clinical course and any resulting organ damage.
