What This Code Means

A blood disorder combining sickle cell disease and hemoglobin C disease with a sudden crisis episode, but the specific type of complication is not documented or specified.

Coding Tips

• •This is a default code when crisis is documented but the specific complication type cannot be determined from the record
• •Query the provider if possible to identify the specific crisis type for more precise coding

Clinical Significance

This unspecified crisis code for sickle-cell/Hemoglobin C disease indicates the patient experienced an acute exacerbation but the specific type of crisis complication was not documented. Hemoglobin SC crises are generally less frequent and less severe than Hemoglobin SS crises but still carry significant morbidity. This code represents a documentation improvement opportunity -- providers should specify the crisis type whenever possible.

Documentation Requirements

• ✓Documentation must confirm the Hemoglobin SC genotype and that an acute crisis is occurring during the encounter.
• ✓Record pain location and severity, vital signs, laboratory findings, treatment administered, and clinical course.
• ✓Query the provider to specify the crisis type (acute chest syndrome, splenic sequestration, cerebral vascular involvement, dactylitis, or other) for more precise coding.
