D63.8Anemia in other chronic diseases classified elsewhere

D63.8 is the ICD-10-CM diagnosis code for anemia in other chronic diseases classified elsewhere. It belongs to category D63 (anemia in chronic diseases classified elsewhere), block D60-D64 (aplastic and other anemias and other bone marrow failure syndromes) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D63, choose D63.8 (other chronic diseases classified elsewhere) only when documentation doesn't support a more specific option: neoplastic disease (D63.0) and chronic kidney disease (D63.1).

Code first underlying disease, such as: diphyllobothriasis (B70.0), hookworm disease (B76.0-B76.9), hypothyroidism (E00.0-E03.9), malaria (B50.0-B54) and 2 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 811 (Red Blood Cell Disorders with MCC, relative weight 1.3988) and DRG 812 (Red Blood Cell Disorders without MCC, relative weight 0.9234), in MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 285.29 (anemia of other chronic disease).
