What This Code Means

This is a blood disorder where a person has both sickle cell disease and thalassemia (two inherited conditions affecting red blood cells), and they are currently experiencing painful swelling in their fingers or toes called dactylitis. Dactylitis is a painful inflammatory condition of the small bones in the hands and feet.

Coding Tips

• •Verify that the patient has confirmed diagnoses of both sickle-cell disease and thalassemia before assigning this combination code; do not assume one condition based on the other
• •Ensure clinical documentation specifically mentions dactylitis (hand-foot syndrome) as a current manifestation; if dactylitis is not documented, use the appropriate sickle-cell thalassemia code without the dactylitis component

Clinical Significance

Dactylitis in unspecified sickle-cell thalassemia represents painful vaso-occlusive swelling of the hands and feet in patients with combined sickle cell and thalassemia genes where the specific thalassemia type is not documented. As with other sickle cell genotypes, dactylitis is primarily seen in young children and may be the first clinical manifestation leading to sickle-cell thalassemia diagnosis.

Documentation Requirements

• ✓Documentation must confirm the sickle-cell thalassemia genotype and the specific diagnosis of dactylitis with affected extremities identified.
• ✓Query for beta-zero vs.
• ✓beta-plus thalassemia specification.
• ✓Record pain severity, swelling characteristics, any imaging findings, treatment, and clinical course.
• ✓Document the patient's age and whether this presentation led to the initial diagnosis.
