About coding Faber's anemia
The ICD-10-CM code for Faber's anemia is D50.9 (Iron deficiency anemia, unspecified).
Within D50, choose D50.9 (unspecified) only when documentation doesn't support a more specific option: secondary to blood loss (chronic) (D50.0), Sideropenic dysphagia (D50.1) and other iron deficiency anemias (D50.8).
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.
