ICD-10 Anemia | ICD-10 Anemia Coding Guidelines

Introduction to ICD-10 Anemia

ICD 10 code for anemia varies depending on the specific type and cause. The most commonly used ICD codes for Anemia are D64.9, D50.0, D53.9, D59.9, and D61.9.

What is Anemia?

Anemia is a blood disorder associated with a low red blood cell (RBC) count in the blood.

A low RBC count can occur due to many reasons:

The body doesn’t make sufficient red blood cells (as in a bone marrow disorder or nutritional deficiency)
It destroys many red blood cells (even the healthy cells) (as in autoimmune diseases).
It loses many red blood cells ( for example, excessive blood loss)

Symptoms of Anemia:

Most of the symptoms of anemia are associated with the lack of oxygen in the body. Following are some symptoms of anemia:

Headache and lethargy
Lightheadedness or dizziness
Pounding heartbeats and arrhythmias
Body aches ( including joint pain and muscle aches)
Growth issues
Pale skin
Shortness of breath

ICD-10-CM Coding for Anemia:

ICD (International Classification of Diseases) coding is introduced by the World Health Organization (WHO). This coding system makes the documentation process simple and efficient. It covers the diagnosis, treatment, and healthcare services in a healthcare system, including billing and insurance.

ICD-10 Anemia Coding Guidelines:

ICD-10 Anemia – Anemia Coding Guidelines

Anemia associated with malignancy:

When a patient is admitted for management id anemia associated with malignancy, the treatment is only for anemia. Appropriate code for malignancy is sequenced as the principal diagnosis or first-listed Dx, followed by the code for Anemia.

Anemia Associated with chemotherapy, radiation therapy, and immunotherapy:

When the reason for admission is the management of anemia associated with the adverse effect of administration of chemotherapy or immunotherapy and the only treatment for anemia. Then always code anemia as a principal or first-listed diagnosis, followed by the appropriate code for neoplasm and then the adverse effect.

List of All ICD-10 codes for anemia and related blood disorders:

What are the 4 Types of Anemia?

Types of anemia differ according to the causes of a low red blood cells count in the body. Following are some specific types of anemia:

#1 What is an Iron Deficiency Anemia?

As evident from its name, iron deficiency anemia refers to the deficiency of Iron in the body. Iron is an essential part of hemoglobin. Hemoglobin is a protein that binds oxygen in red blood cells. It acts as a carrier of oxygen.

#2 What is an Aplastic Anemia?

Aplastic anemia is an acquired or inherited disorder related to bone marrow dysfunction. The bone marrow cannot produce sufficient red blood cells in this kind of anemia. It is because the bone marrow produces different types of blood cells. People undergoing chemotherapy or having diseases that damage bone marrow are at risk of developing this kind of anemia other than those who inherit the causes. Its treatment is more aggressive, including blood transfusions, bone marrow transplants, and medicines.

#3 What is a Pernicious Anemia?

Pernicious anemia is associated with vitamin B12 deficiency in the body. This deficiency can be because of the lesser uptake of vitamin B12 in food or the malabsorption of vitamin B12 in the intestines. Vitamin B12 deficiency leads to decreased production of red blood cells. People having malnutrition and intestinal issues with the absorption of vitamin B12 are at risk of developing this type of anemia. Vitamin B12 supplements and dietary modifications are defined to improve the condition.

#4. What is a Hemolytic Anemia?

Hemolytic anemia refers to the destruction of red blood cells before they complete their standard lifespan (120 days). This destruction can be due to an autoimmune disorder, or it can be inherited (mutation in genes that control red blood cell production and lysis). Treatment of underlying causes, blood transfusions, and medicines may prove helpful.
