About D58.2

D58.2 is the ICD-10-CM diagnosis code for other hemoglobinopathies. It belongs to category D58 (other hereditary hemolytic anemias), block D55-D59 (hemolytic anemias) 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 D58, choose D58.2 (Other hemoglobinopathies) only when documentation doesn't support a more specific option: hereditary spherocytosis (D58.0), hereditary elliptocytosis (D58.1), other specified hereditary hemolytic anemias (D58.8) and hereditary hemolytic anemia, unspecified (D58.9).

Don't report D58.2 together with the conditions in its Excludes1 note: familial polycythemia (D75.0), Hb-M disease (D74.0), hemoglobin E-beta thalassemia (D56.5), hereditary persistence of fetal hemoglobin [HPFH] (D56.4) and 3 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 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 282.7 (other hemoglobinopathies).
