What ICD-10 Codes are Used for Macrocytosis?
Macrocytosis refers to the presence of larger than normal red blood cells, often seen in blood tests. While it can be an indication of a variety of medical conditions, its accurate coding is vital for patient care, research, and medical billing. The ICD-10-CM offers standardized codes for this hematological finding.
Commonly Used ICD-10-CM Codes for Macrocytosis:
D75.81 - Primary polycythemia
A condition where the body produces too many red blood cells, leading to increased blood volume and viscosity.
D75.82 - Secondary polycythemia
Similar to primary polycythemia, but as a response to another condition like chronic hypoxia or tumors secreting erythropoietin.
R71.0 - Polycythemia vera
A type of blood cancer where the bone marrow produces too many red blood cells.
R71.1 - Excessive erythrocytosis
An increase in the number of red blood cells in the blood, which can lead to blood thickening.
(Note: Macrocytosis, as a descriptive term for larger red blood cells, is often a laboratory finding and might not always have a direct ICD-10-CM code. The physician would code for the underlying condition causing the macrocytosis.)

Clinical Information
- Macrocytosis denotes the presence of enlarged red blood cells (RBCs) without an increase in the number of RBCs.
- Often detected during a complete blood count (CBC) test.
- Potential causes include vitamin B12 or folic acid deficiency, alcohol consumption, certain medications, liver disease, and bone marrow disorders.
- Macrocytosis can be a sign of megaloblastic anemia, where the bone marrow produces fewer, but larger RBCs.
- Treatment and management depend on identifying and addressing the underlying cause of macrocytosis.
Synonyms Include:
- Megalocytic anemia
- Macrocytic anemia
- Large red blood cell disorder
- Enlarged erythrocytes
- RBC macrocytosis
Commonly asked questions
A Macrocytosis ICD code should be used when a patient's blood test reveals the presence of abnormally large red blood cells and when there is a related medical diagnosis.
Treatment usually targets the underlying cause. This could range from vitamin supplementation (in the case of deficiency) to medication adjustments or addressing liver disease or alcohol consumption.
A diagnosis code for Macrocytosis signifies the presence of larger-than-normal red blood cells in a patient, which can indicate various underlying conditions.
