What This Code Means

A rare sickle-cell disorder with splenic sequestration, where blood becomes trapped in the spleen causing organ enlargement and anemia.

Coding Tips

• •Splenic sequestration is a medical emergency in children; verify documentation of spleen involvement and hemoglobin drop
• •This complication requires urgent medical intervention and should be clearly documented

Clinical Significance

Other sickle-cell disorders with splenic sequestration describes a medical emergency in rare sickle-cell variants where sickled red blood cells become trapped in the spleen, causing rapid splenic enlargement, severe anemia, and potentially fatal hypovolemic shock. This complication is most common in young children before autosplenectomy occurs and can progress rapidly from onset to cardiovascular collapse. Immediate transfusion and potentially emergent splenectomy may be required.

Documentation Requirements

• ✓Document the specific sickle-cell variant and evidence of splenic enlargement on physical examination or imaging.
• ✓Record hemoglobin drop from baseline (typically a decrease of 2 g/dL or more), platelet count, and reticulocyte count.
• ✓Include vital signs demonstrating hemodynamic stability or instability.
• ✓Document any transfusion therapy administered, fluid resuscitation, and whether splenectomy was performed or planned.
