ICD 10 codes for Anemia – Anemia Coding Cheat Sheet

Anemia isn’t a one-size-fits-all diagnosis; it comes in various forms, each with its own underlying cause. Some cases are transient, while others become chronic, and the severity can vary significantly. Left untreated, anemia can give rise to serious health complications, ranging from pregnancy-related issues to profound fatigue, heart complications, and in severe instances, even mortality.

Treating anemia encompasses a spectrum of approaches, from simple supplementation with medication to more complex medical procedures. The condition generally arises from one of three key factors: a reduced ability of the body to generate new red blood cells or hemoglobin, an upswing in blood loss typically stemming from bleeding, or an underlying illness triggering accelerated destruction of red blood cells.

However, accurately documenting the different types of anemia for claim submission and reimbursement hinges on a deep understanding of the intricate world of medical billing and coding guidelines. This is where the services of a reputable and experienced medical billing and coding company can prove invaluable, aiding physicians in navigating the complex landscape of claim submission.

What is Anemia?

Anemia is a blood disorder typically characterized by an insufficiency of red blood cells. In this condition, the number of red blood cells falls below the normal range, or the quantity of hemoglobin within each red blood cell is lower than the standard level. Anemia is predominantly observed in women. The deficiency of hemoglobin, a crucial protein, in anemia disrupts the equitable distribution of oxygen to the body’s tissues. Individuals with anemia often experience persistent fatigue, paleness of the skin, shortness of breath, and dizziness, and may notice coldness in their hands and feet. Headaches, irregular heartbeats, and even chest pain can occur in severe cases.

There are several common types of anemia frequently encountered in medical records:

  1. Iron Deficiency Anemia: This type of anemia arises from a significant shortage of iron in the blood. It is often observed in women, primarily attributed to heavy menstrual bleeding. Iron is a crucial element in the production of hemoglobin, the protein in red blood cells (RBCs) responsible for carrying oxygen.
  2. Sickle Cell Anemia: Sickle cell anemia is a genetic disorder characterized by a distinctive crescent shape assumed by RBCs. These abnormally shaped RBCs face difficulty traveling through blood vessels and are incapable of efficiently delivering oxygen to the body’s organs.
  3. Vitamin Deficiency Anemia: As the name implies, this form of anemia stems from a deficiency in essential vitamins such as folate, B12, and C. This deficiency directly impacts the production of healthy RBCs, leading to anemia.
  4. Blood Loss Anemia: An individual can develop anemia due to substantial blood loss. Once the underlying cause of the bleeding is addressed, the person typically returns to a healthy state, referred to as acute blood loss anemia. However, in some cases, such as chronic conditions like stomach ulcers, occult (hidden) blood loss can persist over an extended period, resulting in anemia termed chronic blood loss anemia.

Anemia ICD 10 Codes and Guidelines:

When anemia coexists with another medical condition, specific coding guidelines come into play. It’s imperative to select the appropriate ICD-10 code based on the root cause of anemia and sequence it correctly. In such instances, the medical record must contain clear and concise documentation elucidating the cause of the anemia. Should any ambiguity arise, coders may need to reach out to the healthcare provider for clarification.

Commonly Used Anemia ICD 10 Code List :

Anemia, a condition characterized by a deficiency of red cells or hemoglobin in the blood, has multiple corresponding ICD-10-CM codes:

  • D64.9 – Anemia, unspecified: This code is used when anemia is diagnosed, but its type is not specified.
  • D50.0 – Iron deficiency anemia secondary to blood loss (chronic): This code refers to anemia due to chronic blood loss, usually caused by gastrointestinal bleeding.
  • D50.9 – Iron deficiency anemia, unspecified: This code is used for anemia caused by iron deficiency, but further details are not given.
  • D62 – Acute posthemorrhagic anemia: This code is used for anemia following significant blood loss, such as after surgery or due to injury.
  • D53.9 – Nutritional anemia, unspecified: This code covers anemia resulting from dietary deficiencies, excluding iron deficiency. 

ICD 10 code for iron deficiency and other related codes are as under:

  • 8: Anemia in other chronic diseases classified elsewhere.
  • D64: Other anemias
  • 0: Hereditary sideroblastic anemia
  • 1: Secondary sideroblastic anemia due to disease
  • 2: Secondary sideroblastic anemia due to drugs and toxins
  • 3: Other sideroblastic anemias
  • 4: Congenital dyserythropoietic anemia
  • 8: Other specified anemias
  • 81: Anemia due to antineoplastic chemotherapy
  • 89: Other specified anemias
  • 9: Anemia, unspecified
  • D65: Disseminated intravascular coagulation [defibrination syndrome]
  • D66: Hereditary factor VIII deficiency
  • D67: Hereditary factor IX deficiency
  • D68: Other coagulation defects
  • 0: Von Willebrand disease
  • 00: Unspecified
  • 01: Type 1
  • 02: Von Willebrand disease, type 2


Common Coding Challenges in Anemia Coding:

  1. Underlying Cause Identification: Anemia can be a symptom of various underlying conditions, such as nutritional deficiencies, chronic diseases, or genetic disorders. Identifying the root cause is crucial for accurate coding.
  2. Specificity of Codes: There are numerous types and causes of anemia, each requiring specific ICD-10 codes. Choosing the correct code that accurately reflects the patient’s condition can be challenging. The ICD-10 coding system undergoes regular updates, and coders need to stay informed about changes and revisions to the codes related to anemia.
  3. Documentation Quality: Accurate coding relies on the quality of documentation in the medical record. Incomplete or unclear documentation can make it difficult to select the appropriate code. Coders may need to query healthcare providers for additional information or clarification when documentation lacks specificity.
  4. Code Sequencing: When anemia coexists with another condition, determining the primary diagnosis and sequencing the codes correctly can be tricky. For e.g., differentiating between chronic and acute anemia is important for coding accuracy. Chronic anemia may require ongoing treatment and monitoring.

Addressing these challenges in anemia coding requires a combination of clinical knowledge, accurate documentation practices, ongoing education, and adherence to coding guidelines.
