What This Code Means

Sickle cell disease with an acute crisis causing severe pain and swelling in the hands and feet due to blocked blood vessels in these areas.

Coding Tips

• •Dactylitis (hand-foot syndrome) is often seen in children; document affected extremities and clinical presentation
• •Ensure acute crisis status is documented; this code indicates dactylitis as the crisis complication

Clinical Significance

Dactylitis (hand-foot syndrome) in Hemoglobin SS disease is a painful vaso-occlusive crisis affecting the small bones of the hands and feet, often the earliest clinical manifestation of sickle cell disease appearing in infants between 6 months and 2 years of age. It presents with bilateral painful swelling of the dorsal aspects of the hands and feet with underlying bony infarction. While typically self-limiting, it is a predictor of severe sickle cell disease course and may be the presenting symptom that leads to diagnosis.

Documentation Requirements

• ✓Documentation must confirm Hemoglobin SS genotype and the specific diagnosis of dactylitis with description of affected extremities, swelling, tenderness, and imaging findings if obtained (radiographic periosteal elevation or bony changes).
• ✓Record pain management administered, clinical course, and any concurrent fever or infection.
• ✓Note the patient's age at presentation as this carries prognostic significance for disease severity.
