Also known as
Alpha-thalassemia trait
Reduced alpha-globin chain production, usually asymptomatic.
Beta-thalassemia trait
Reduced beta-globin chain production, often mild anemia.
Thalassemia trait, unspecified
Thalassemia trait where type is not specified.

| Alpha thalassemia minor |
Coding Thalassemia Trait without specifying the type (alpha or beta) leads to inaccurate reporting and potential payment errors.
Miscoding Thalassemia Trait (carrier) as Thalassemia Major (disease) impacts severity reporting and resource allocation.
Claims without proper documentation (e.g., lab results, HGB electrophoresis) to support Thalassemia Trait diagnosis can trigger audits and denials.
Patient presents with mild microcytic anemia, identified during routine complete blood count (CBC) testing or pre-operative screening. The patient denies symptoms of anemia such as fatigue, weakness, or shortness of breath. Family history is significant for anemia, specifically possible thalassemia. Physical examination is unremarkable. Laboratory findings reveal microcytosis, hypochromia, and an elevated red blood cell (RBC) count with a mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) below the reference range. Peripheral blood smear demonstrates anisocytosis and poikilocytosis with target cells. Hemoglobin electrophoresis or high-performance liquid chromatography (HPLC) confirms the diagnosis of thalassemia trait, specifically alpha or beta thalassemia minor, showing reduced levels of either alpha or beta globin chains respectively. Iron studies, including serum ferritin and iron saturation, are normal, ruling out iron deficiency anemia. Genetic counseling may be considered for family planning purposes. Patient education provided regarding the benign nature of thalassemia trait, emphasizing that no specific treatment is typically required. Follow-up is not routinely indicated unless the patient develops symptoms or other hematologic abnormalities. ICD-10 code D56.9 (Thalassemia, unspecified) may be used if further specification of alpha or beta thalassemia minor is not documented. CPT codes for the laboratory tests performed, such as 85025 (CBC), 85018 (peripheral blood smear), and 83020 (hemoglobin electrophoresis), should be included for billing purposes.
