Macrocytic Anemia ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Macrocytic Anemia

Macrocytic anemia is a type of anemia characterized by abnormally large red blood cells. Here are commonly used ICD-10-CM codes for macrocytic anemia, along with brief clinical descriptions:

• D51.0 - Vitamin B12 deficiency anemia due to selective vitamin B12 malabsorption with protein-bound vitamin B12: Used when macrocytic anemia is caused by selective vitamin B12 malabsorption with a specific protein-bound vitamin B12 deficiency.
• D51.1 - Vitamin B12 deficiency anemia due to selective vitamin B12 malabsorption with intrinsic factor deficiency: Applied when macrocytic anemia results from selective vitamin B12 malabsorption with intrinsic factor deficiency, affecting vitamin B12 absorption.
• D51.2 - Transcobalamin II deficiency: Utilized for macrocytic anemia caused by a deficiency in transcobalamin II, a protein involved in vitamin B12 transport.
• D51.3 - Other dietary vitamin B12 deficiency anemia: Used when macrocytic anemia is related to dietary vitamin B12 deficiency, not specifically due to malabsorption issues.
• D51.8 - Other vitamin B12 deficiency anemias: Applied for other types of vitamin B12 deficiency-related macrocytic anemias not classified under the previous codes.
• D51.9 - Vitamin B12 deficiency anemia, unspecified: Utilized when macrocytic anemia is due to vitamin B12 deficiency, but the specific cause is unspecified.

Which Macrocytic Anemia ICD Codes are Billable

The billable status of the mentioned ICD-10 codes for macrocytic anemia varies:

• D51.0 - Vitamin B12 deficiency anemia due to selective vitamin B12 malabsorption with protein-bound vitamin B12: Yes, billable. Medical expenses for this type of vitamin B12 deficiency-related macrocytic anemia can be claimed.
• D51.1 - Vitamin B12 deficiency anemia due to selective vitamin B12 malabsorption with intrinsic factor deficiency: Yes, billable. Costs associated with macrocytic anemia due to intrinsic factor deficiency can be reimbursed.
• D51.2 - Transcobalamin II deficiency: Yes, billable. Medical expenses for macrocytic anemia resulting from transcobalamin II deficiency can be claimed.
• D51.3 - Other dietary vitamin B12 deficiency anemia: Yes, billable. Expenses related to dietary vitamin B12 deficiency-related macrocytic anemia can be claimed.
• D51.8 - Other vitamin B12 deficiency anemias: Yes, billable. Medical expenses for other vitamin B12 deficiency-related macrocytic anemias can be claimed.
• D51.9 - Vitamin B12 deficiency anemia, unspecified: Yes, billable. Costs associated with unspecified vitamin B12 deficiency-related macrocytic anemia can be reimbursed.

Clinical Information

• Macrocytic Anemia is a type of anemia characterized by abnormally large red blood cells (macrocytes).
• It's typically diagnosed through a complete blood count (CBC) and peripheral blood smear, which reveals the enlarged red blood cells.
• The most common causes of macrocytic anemia are deficiencies in vitamin B12 or folic acid, which can result from poor dietary intake, malabsorption, or other medical conditions.
• Treatment often involves identifying and addressing the underlying cause of the vitamin deficiency, including dietary changes, oral supplements, or injections.
• In cases where the anemia is severe or rapidly progressing, blood transfusions and additional medical interventions may be necessary.
• Healthcare practitioners should emphasize the importance of treatment adherence and regular follow-up to monitor red blood cell counts and address the underlying cause.
