Anemia ICD 10 Code: D64.9 Unspecified
Also known as a low blood count, anemia is a common condition that affects people of all ages. It occurs when the body does not have enough healthy red blood cells or hemoglobin to carry oxygen from the lungs to the rest of the body.
A lack of healthy red blood cells can lead to several health problems, including:
- Fatigue
- Headaches
- Weakness
- Dizziness
- Shortness of breath
- Irregular Heartbeat
Several factors can cause anemia. These include nutritional deficiencies caused by an unhealthy or poor diet, blood loss due to heavy periods, internal bleeding, intestinal problems, chronic diseases, genetic conditions, and infections. People with anemia often feel tired and weak.
Microcytic Anemia
Microcytic anemia is often caused by and is identified by smaller-than-normal red blood cells. Other common causes include thalassemia, lead poisoning, and anemia related to chronic diseases.
Normocytic Anemia
Normocytic anemia is characterized by red blood cells that are normal in size. Unlike microcytic anemia, which involves smaller red blood cells, and macrocytic anemia, which involves larger ones, this type has red blood cells of a normal size but in lower numbers. It can develop due to conditions such as chronic kidney disease, cancer, bone marrow problems, and the use of certain medications.
Macrocytic Anemia
As the name suggests, macrocytic anemia is characterized by larger-than-normal red blood cells. It is commonly caused by a deficiency of vitamin B12 or folic acid. Other possible causes include liver disease, alcoholism, and the use of certain medications.
Understanding The D64.9 Diagnosis Code for Anemia
Before exploring the different types of anemia and the ICD-10 codes used to classify them, let’s take a closer look at ICD-10 Code D64.9 – Anemia, Unspecified.
What is D64.9: Anemia, Unspecified
In medical billing, D64.9 is a billable ICD-10 code used to identify ‘anemia, unspecified’. This code falls under the chapter covering diseases of the blood and blood-forming organs, as well as disorders of the immune mechanism.
Brief Explanation of D64.9
Healthcare providers generally use this code in medical records when a patient has anemia, but the specific type or cause has not been identified. D64.9 indicates that the documentation does not specify the exact cause or type of anemia. It may be used when complete diagnostic testing has not been performed or when the available test results do not provide a clear diagnosis.
Symptoms of D64.9 Anemia Explained
The symptoms of anemia can vary depending on its underlying cause. When a chronic disease causes anemia, its symptoms may be difficult to recognize because they can overlap with those of the underlying condition. In some cases, anemia is discovered during tests performed for another health problem.
Some patients may not experience noticeable signs or symptoms, depending on the cause and severity of their anemia. Common symptoms include weakness, pale skin, irregular heartbeat, fatigue, shortness of breath, lightheadedness, chest pain, headaches, and cold hands or feet.
Here are some of the most common symptoms of anemia.
Fatigue and Weakness
Fatigue and weakness are among the most common signs of anemia. People with this condition often feel tired, lack energy, and struggle to complete their daily activities. This happens because the blood cannot carry enough oxygen to different parts of the body. As a result, the person may experience low energy, exhaustion, and drowsiness.
Shortness of Breath
When a person has anemia, the body may try to make up for the lack of oxygen in the tissues by increasing the heart rate and breathing rate.
As a result, patients may experience shortness of breath during physical activities. For example, they may start breathing heavily after climbing stairs, walking quickly, or performing physically demanding tasks.
Pale or Yellowish Skin
Anemia reduces the number of healthy red blood cells or the amount of hemoglobin available to carry oxygen. This can affect blood circulation and the appearance of the skin and mucous membranes. As a result, people with anemia may develop pale skin. In some cases, certain types of anemia can also cause a yellowish appearance of the skin.
Dizziness and Lightheadedness
When the blood does not carry enough oxygen to the body’s tissues, a person may experience weakness and fatigue. If the brain does not receive an adequate oxygen supply, dizziness and lightheadedness may also occur. These symptoms can be more noticeable when a patient stands up suddenly or performs physical activities.
Fast or Irregular Heartbeat
A fast or irregular heartbeat can also be a sign of anemia. An irregular heartbeat is known as arrhythmia and should not be ignored. Although it can occur for several reasons, including stress, excessive caffeine consumption, and certain medications, anemia can also contribute to this problem.
Important: The symptoms described above can vary from person to person depending on their overall health, the type of anemia, and its severity. If you or someone you know experiences these symptoms, consult a healthcare provider for an accurate assessment and appropriate treatment.
ICD-10 Codes for Different Types of Anemia
If you want to learn about the different types of anemia and their specific ICD-10 codes, the following section provides an overview of the main categories and their related codes.
Iron Deficiency Anemia
Iron deficiency anemia occurs when the body does not have enough iron. Iron is an essential mineral that helps the body produce hemoglobin, which allows red blood cells to carry oxygen. When iron levels are too low, the body may not produce enough hemoglobin for healthy red blood cells.
Possible causes of iron deficiency anemia include malnutrition, frequent blood donation, digestive conditions such as Crohn’s disease, intense endurance training or physical exercise, and surgical removal of part of the digestive tract.
ICD-10 Code for Iron Deficiency Anemia: D50
The following ICD-10 codes are associated with iron deficiency anemia:
- D50.0: Iron deficiency anemia secondary to blood loss (chronic)
- D50.1: Sideropenic dysphasia
- D50.8: Other iron deficiency anemias
- D50.9: Iron deficiency anemia, unspecified
Vitamin Deficiency Anemia
Vitamin deficiency anemia occurs when the body does not have enough essential vitamins, particularly vitamin B12 and folate, to produce healthy red blood cells. Healthcare providers may recommend dietary changes, vitamin supplements, or other treatments to address deficiencies in folic acid and vitamin B12.
ICD-10 Codes for Vitamin Deficiency Anemia: D51
- D51.0: Intrinsic factor deficiency causing lack of vitamin B12
- D51.1: Lack of vitamin B12 anemia due to malabsorption of B12 with proteinuria.
- D51.2: Transcobalamin II deficiency
- D51.3: Other dietary vitamin B12 deficiency anemia
- D51.8: Other vitamin B12 deficiency anemias
- D51.9: Vitamin B12 deficiency anemia, unspecified
Folate Deficiency Anemia
Folate deficiency anemia develops when the body does not have enough folic acid. Folate is a type of B vitamin that helps produce healthy red blood cells. A deficiency can reduce the number of red blood cells or cause them to become larger than normal. Common symptoms of folate deficiency anemia include fatigue, pale skin, and a sore or tender tongue.
ICD-10 Codes for Folate Deficiency Anemia: D52
- D52.0: Dietary folate deficiency anemia
- D52.1: Drug-induced folate deficiency anemia
- D52.8: Other folate deficiency anemias
- D52.9: Folate deficiency anemia, unspecified
Other Nutritional Anemias
Nutritional anemias develop when the body lacks the vitamins and minerals needed to produce healthy red blood cells. Common examples include megaloblastic anemia and iron deficiency anemia, although these conditions have different underlying causes. Megaloblastic anemia may result from a deficiency of folate or vitamin B12, while iron deficiency anemia develops when the body does not have enough iron. Other possible causes include deficiencies in vitamins A, B2, B6, C, D, and E, as well as zinc and copper.
ICD-10 Codes for other nutritional anemias: D53
- D53.0 – Protein deficiency anemia
- D53.1 – Other megaloblastic anemias, not elsewhere classified
- D53.2 – Scorbutic anemia
- D53.8 – Other specified nutritional anemias
- D53.9 – Nutritional anemia, unspecified
Hemolytic Anemia
Hemolytic anemia occurs when red blood cells are destroyed faster than the body can replace them. This process is known as hemolysis. It can result from inherited conditions, infections, certain medications, or autoimmune disorders.
Common symptoms of hemolytic anemia include fatigue, jaundice, dark urine, pale skin, fever, weakness, confusion, and dizziness. There are several types of hemolytic anemia, including conditions associated with sickle cell disease, thalassemia, enzyme disorders, and other inherited conditions.

Aplastic Anemia
Aplastic Anemia is a rare but serious blood disorder. It occurs when the bone marrow cannot produce enough new blood cells for the body to function properly. Depending on its severity, aplastic anemia may develop gradually or progress quickly.
Several factors can cause this condition, including long-term exposure to toxic chemicals, viral infections, inherited disorders, cancer treatments, and certain medications. One possible treatment is a blood transfusion, which helps increase the number of red blood cells in the body.
Doctors may also recommend a bone marrow transplant when the patient’s bone marrow is damaged or unable to produce healthy blood cells. The following codes help healthcare providers document the condition and claim their reimbursements from the payors.
ICD-10 Codes for Aplastic Anemia: D60
- D60 – Acquired pure red cell aplasia [erythroblastopenia]
- D61 – Other aplastic anemias and other bone marrow failure syndromes
- D61.0 – Constitutional aplastic anemia
- D61.1 – Drug-induced aplastic anemia
- D61.2 – Aplastic anemia due to other external agents
- D61.3 – Idiopathic aplastic anemia
- D61.8 – Other specified aplastic anemias and other bone marrow failure syndromes
- D61.9 – Aplastic anemia, unspecified
Anemia for Chronic Disease
Anemia for Chronic Disease, also known as ACD, occurs when chronic illnesses, infections, or other medical conditions cause inflammation in the body. This inflammation can affect red blood cell production and the way the body uses iron, leading to anemia. ACD is often mild to moderate, and some patients may not experience noticeable symptoms.
There is no single treatment that works for every case of this condition. Instead, doctors usually focus on treating the underlying disease. If the patient has severe symptoms, doctors may consider synthetic erythropoietin injections. Erythropoietin is a hormone normally produced by the kidneys that helps the body make red blood cells. Treatment may help improve red blood cell production and reduce fatigue.
ICD-10 Codes for Anemia Due to Chronic Disease classified elsewhere: D63
- D63.0: Anemia in neoplastic disease
- D63.1: Anemia in chronic kidney disease
- D63.8: Anemia in other chronic diseases classified elsewhere

- D64.0: Genetic sideroblastic anemia
- D64.1: Secondary sideroblastic anemia due to disease
- D64.2: Secondary sideroblastic anemia due to drugs and toxins
- D64.3: Other sideroblastic anemia
- D64.8: Other specified anemias
- D64.9: Anemia, unspecified
Coding for Anemia: Challenges Faced by Healthcare Providers
Healthcare providers, medical billers, and coders face several challenges when documenting and billing for anemia. Some of the most common coding challenges in medical billing are explained below.
Identifying The Root Cause
Anemia can develop due to several underlying conditions. These may include nutritional deficiencies, chronic diseases, or inherited disorders. To ensure correct coding and timely reimbursements for the services provided, healthcare providers must identify the underlying cause whenever possible and document the appropriate ICD-10 code.
Coding accuracy
As discussed above, anemia has many different types and causes, and each type may require a specific ICD-10 code. Selecting the correct code that accurately represents the patient’s condition can be challenging.
The International Classification of Diseases system is regularly updated. Therefore, healthcare providers, medical billers, and coders must stay current with the recent updates related to anemia and its classification. Keeping up with these changes helps maintain accurate records, protect practice credibility, stay away from denials, and ensure proper reimbursement for medical services.
Accurate Coding and Documentation
Accurate coding depends on complete and clear documentation. If either one is incorrect or incomplete, it can create problems with the entire billing process. For example, a claim may be denied because the medical records lack important details, even when the correct code has been selected.
Similarly, incorrect coding can prevent reimbursement even when the documentation is complete and accurate. To avoid these problems, medical billers and coders should work closely with healthcare providers to obtain all the necessary information, including the specific type of anemia being treated.
Code Sequencing
When anemia occurs alongside another medical condition, selecting the correct primary diagnosis and sequencing codes can be challenging. Physicians and medical coders must understand which condition should be listed first and how the other diagnoses should be reported.
For example, failing to distinguish between Hemolytic Anemia and Aplastic Anemia can lead to coding errors during documentation and claim preparation.
These mistakes can affect revenue collection from the payors for the medical services provided. Similar challenges arise when distinguishing between acute and chronic anemia, as these conditions may have different coding requirements and treatment approaches.
Managing these situations requires proper knowledge, accurate documentation, regular training, and compliance with coding guidelines. By following the correct coding procedures, healthcare providers can reduce billing errors and improve reimbursement outcomes.
Conclusion
Anemia is a common health condition that affects millions of Americans and people around the world. Its different types, causes, and levels of severity can make diagnosis, treatment, and medical billing challenging. Healthcare providers, medical billers, and coders may sometimes struggle to manage the various ICD-10 codes required to identify and document each type of anemia accurately.
