Clinical Information

Specific Coding for Thalassemia

Non-specific codes like D56 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for thalassemia:

  • BILLABLE CODE - Use D56.0 for Alpha thalassemia
  • BILLABLE CODE - Use D56.1 for Beta thalassemia
  • BILLABLE CODE - Use D56.2 for Delta-beta thalassemia
  • BILLABLE CODE - Use D56.3 for Thalassemia minor
  • BILLABLE CODE - Use D56.4 for Hereditary persistence of fetal hemoglobin [HPFH]
  • BILLABLE CODE - Use D56.5 for Hemoglobin E-beta thalassemia
  • BILLABLE CODE - Use D56.8 for Other thalassemias
  • BILLABLE CODE - Use D56.9 for Thalassemia, unspecified

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Patient Education


Thalassemia

Thalassemias are inherited blood disorders. If you have one, your body makes fewer healthy red blood cells and less hemoglobin. Hemoglobin is a protein that carries oxygen to the body. That leads to anemia. Thalassemias occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent.

Thalassemias can be mild or severe. Some people have no symptoms or mild anemia. The most common severe type in the United States is called Cooley's anemia. It usually appears during the first two years of life. People with it may have severe anemia, slowed growth and delayed puberty, and problems with the spleen, liver, heart, or bones.

Doctors diagnose thalassemias using blood tests. Treatments include blood transfusions and treatment to remove excess iron from the body. If you have mild symptoms or no symptoms, you may not need treatment. In some severe cases, you may need a bone marrow transplant.
