D63.0 is a billable ICD-10-CM diagnosis code for anemia in neoplastic disease. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 811 through 812. The code is a manifestation code that cannot be reported as the principal diagnosis. Coders also document this condition as anemia in malignant neoplastic disease. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Aplastic anemia and Conditions due to neoplasm or the treatment of neoplasm.

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Anemia
If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.

Questions About D63.0Overview
What is the ICD-10 code for anemia in neoplastic disease?
The ICD-10-CM code for anemia in neoplastic disease is D63.0 (sometimes written as D630). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is D63.0 (Anemia in chronic diseases classified elsewhere) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report anemia in neoplastic disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D63.0 group to?
On inpatient claims, anemia in neoplastic disease maps to MS-DRG 811, 812, with relative weights from 0.9182 to 1.4043 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D63.0 be a principal diagnosis?
No. This is a manifestation code: anemia in neoplastic disease describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
What is the ICD-9 equivalent of D63.0?
Under the General Equivalence Mappings, anemia in neoplastic disease converts to ICD-9-CM 285.22 (anemia in neoplastic dis). The mapping is a direct match.
