Cpt Code D63.8, Anemia of chronic disease ICD 10 is much more than a billing code; it is a deciding factor in patient complexity, documentation accuracy, and revenue integrity. At Providers Care Billing LLC, we know that correct coding = correct reimbursement + audit immunity, particularly for conditions like anemia in chronic diseases classified elsewhere. This guide equips U.S. healthcare professionals with the skills they need to become the masters of ICD-10, D63.8 specificity, prevent denials, and streamline clinical billing processes.
Have you ever heard that anemia occurs in 30 percent of patients with chronic inflammations—and care providers pay millions of dollars in coding mistakes?
What do you know about Anemia?
Anemia is a blood condition that is normally described by insufficiency of red blood cells, often classified under the ICD-10-CM code D63.8 for anemia in chronic diseases classified elsewhere. In this state, the red blood cell volume would be either below the normal level, or less hemoglobin would be contained in the red blood cell as compared to the normal level, and it usually has a particular diagnosis code. The most affected group is women when it comes to Anemia.
Types of Anemia
1. Iron Deficiency Anemia:
This form of anemia is about a severe deficiency of blood iron. It commonly occurs in females, but it has been mostly attributed to excessive menstrual bleeding. Iron also has a major role to play in the hemoglobin formation of the protein in the red cells (RBCs) responsible for the transportation of oxygen, especially in the chronic disease patients diagnosed with anemia.
2. Sickle Cell Anemia:
Sickle cell anemia is an inherited disorder, and this is because it is crescent-shaped in nature due to RBC. Such abnormally shaped RBCs have a challenge in moving through the blood vessels, and they cannot deliver enough oxygen to the other organs in the body efficiently.
3. Vitamin Deficiency Anemia:
This is an anemia caused due to a lack of the necessities of life, i.e., essential vitamins like folate and B12, and C, as the name suggests. This shortage has direct effects on the current production of healthy RBCs, thus resulting in anemia.
4. Blood Loss Anemia:
Anemia can occur in an individual due losing a loss of blood. As soon as the cause that has led to the bleeding is remedied, the individual is likely to revert to a healthy condition, a condition called anemia, which is described as an acute blood loss.
What Is Anemia of Chronic Disease?
It is also called anemia of inflammation, and it occurs. When chronic diseases such as rheumatoid arthritis, CKD, cancer, or infections affect the production of red cells or the red cell maturation process called erythropoiesis, and lead to ways the body metabolizes iron through hepcidin-mediated processes getting out of control. Ferritin concentrations are normal to high except in the case of TIBC being normal to low, and hemoglobin is below 12 g/dL (in women) or 13 g/dL (in men).
Scenario
A 58 year old dialysis patient who had rheumatoid arthritis also complained of tiredness and pale hues, indicative of anemia in other chronic diseases. Labs: Hb 9.0 g/dL, high ferritin level, raised CRP. He did not have blood loss or iron deficiency as causes of her anemia; rather, he had anemia of chronic disease as a complication of CKD and RA. Both diagnoses done correctly led to optimal reimbursement.
ICD 10 Codes and Guidelines of Anemia
In case anemia exists along with other medical conditions, there are designated guidelines for coding. There is a necessity to choose the right ICD-10 code depending on the cause of anemia at the root and put it in the right order, particularly for anemia in chronic diseases classified.
Since anemia often coexists with liver conditions, it’s important to also understand how to bill for related diagnoses like unspecified liver cirrhosis (ICD-10 Code K74.60) in complex chronic cases.
D63.1—Chronic Kidney Disease and Anemia:
It shows whether CKD is the underlying condition that leads to anemia. It is a display code; first, you must code the underlying CKD. Requirements: documented linkage, eGFR < 60, and Hb < 10 (or as recommended).
D63.0—Anemia due to a malignancy:
It is used in the situation with cancer-induced anemia (e.g., in the case of chemotherapy or inflammation caused by a tumor).
D63.0—Anemia in neoplastic disease:
Billable; set aside for malignancy-related anemia, which may require a different diagnosis code than anemia in chronic diseases classified elsewhere.
D63.8—Anemia of Chronic Diseases:
Anemia, D63.8 due to chronic causes, not kidney-cause or cancer-cause, e.g., autoimmune disease, chronic infections, or heart disease.
D64.9—Anemia, Unspecified:
Preserve in cases in which the cause remains in doubt following adequate workup. It is to be used after the rule of other types is eliminated.
D62—Acute posthemorrhagic anemia:
It is applied in the case of anemia due to severe blood loss, e.g., after operations or due to injury.

Common Coding Difficulties in Anemia Coding:
1. Underlying Cause Identification:
Anemia may be an indication of other underlying issues, including a lack of nutrients, persistent disorders, and hereditary conditions. It is very important to identify the root cause in relation to accurate coding.
2. Specificity of Codes:
The types and causes of anemia are numerous, and all these are linked to various D63.8 ICD-10 codes. It may be difficult to select the right code that portrays the situation of the patient correctly. The ICD-10 coding system is a system that experiences periodic updates, and coders should remain updated on changes and the revisions of codes linked to anemia.
3. Documentation Quality:
Proper coding relies on the results of documentation in the medical record. There may be lacunae or unintelligible documentation, which may render the selection of the correct code hard. In cases where documentation is not so specific as in the case of D63.8, the coders may be obligated to put queries to the healthcare provider so as to seek further information or clarification.
4. Code Sequencing:
When there is another condition combined with anemia, it may be a challenge to rank the codes in the correct order so as to identify the primary diagnosis. e.g., It may be necessary to distinguish between chronic and acute anemia in order to code properly. Chronic anemia could call for continuous treatment and observation.
Conclusion
Proper coding of D63.8, ICD-10 for anemia of chronic disease is necessary, not just to receive reimbursement, but also to comply with the requirements and finally to have clinical clarity. When using the special tools Providers Care Billing LLC offers, you reduce denials, reinforce audits, and ensure document accuracy. Anemia coding should not be your liability but an asset.
FAQS
- Would it be possible to have D63.1 without giving mention of CKD stage?
No. Staging of CKD is to be reported (e.g., N18.4 stage 4) that will support D63.1
- Will we be able to utilize it as D63.8 as be primary?
Yes, where the primary cause of the care is anemia. The second is the chronic disease code.
