ICD-10-CM D58.2
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

D58.2 is a billable ICD-10-CM diagnosis code for other hemoglobinopathies. 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. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Hemolytic anemia.

D58.2 no longer risk-adjusts for Medicare Advantage: it mapped to HCC 48 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 48, ESRD (V21) category 48, and ESRD (V24) category 48 for payment year 2026.

Clinical InformationClinical

  • Hemoglobinopathies

    a group of inherited disorders characterized by structural alterations within the hemoglobin molecule.

  • Pseudoxanthoma Elasticum

    an inherited disorder of connective tissue with extensive degeneration and calcification of elastic tissue primarily in the skin, eye, and vasculature. at least two forms exist, autosomal recessive and autosomal dominant. this disorder is caused by mutations of one of the atp-binding cassette transporters. patients are predisposed to myocardial infarction and gastrointestinal hemorrhage.

  • Hemoglobin C Disease

    a disease characterized by compensated hemolysis with a normal hemoglobin level or a mild to moderate anemia. there may be intermittent abdominal discomfort, splenomegaly, and slight jaundice.

  • Hemoglobin E Disease

    a condition characterized by the presence of a variant of normal hemoglobin (hemoglobin e), which is caused by mutation(s) in the gene encoding the beta subunit of the hemoglobin molecule.

  • Sickle Cell-Hemoglobin E Disease|Hemoglobin SE Disease

    a variant of sickle cell disease due to heterozygosity for hemoglobin s and hemoglobin e mutations. patients present with the symptoms of sickle cell disease but the symptoms are less frequent and severe compared to patients with hemoglobin ss disease.

  • ABCC6 wt Allele|ABC34|ARA|ATP-Binding Cassette, Sub-Family C (CFTR/MRP), Member 6 wt Allele|ATP-Binding Cassette, Subfamily C, Member 6 Gene|EST349056|GACI2|MLP1|MOAT-E|MOATE|MRP6|PXE|PXE1|Pseudoxanthoma Elasticum Gene|URG7

    human abcc6 wild-type allele is located in the vicinity of 16p13.1 and is approximately 75 kb in length. this allele, which encodes multidrug resistance-associated protein 6, plays a role in the active transport of drugs across the plasma membrane. mutation of the gene is associated with pseudoxanthoma elasticum and generalized arterial calcification of infancy type 2.

  • Pseudoxanthoma Elasticum

    a rare, progressive, autosomal recessive inherited disorder caused by mutations in the abcc6 gene. it is characterized by calcification and fragmentation of the elastic fibers of the skin, retina, and cardiovascular system. signs and symptoms include skin plaques and bumps, thickened skin, retinal hemorrhage and obstruction of the blood vessels.

  • Spastic Paraplegia 56|Autosomal Recessive Spastic Paraplegia-56 with or without Pseudoxanthoma Elasticum|SPG56

    an autosomal recessive subtype of hereditary spastic paraplegia caused by mutation(s) in the cyp2u1 gene, encoding cytochrome p450 2u1.

  • Hemoglobin C Disease

    an autosomal recessive hemoglobinopathy with a mild clinical course. most patients are asymptomatic. when symptoms appear, they include mild hemolytic anemia and occasionally jaundice.

  • Sickle Cell-Hemoglobin C Disease|HbSC|Hemoglobin SC Disease|Hemoglobin SC Disease

    a hemoglobinopathy that is considered a hybrid of sickle cell disease and hemoglobin c disease. patients present with the symptoms of sickle cell disease but the latter are less frequent and severe compared to sickle cell disease.

  • Vaso-Occlusive Crisis in Sickle Cell-Hemoglobin C Disease|Vaso-Occlusive Crisis in Hemoglobin SC Disease|Vaso-Occlusive Crisis of Hemoglobin SC Disease|Vaso-Occlusive Crisis of Sickle Cell-Hemoglobin C Disease

    sickle cell-hemoglobin c disease exacerbated by sudden pain caused by sickled erythrocytes impeding blood flow within a vessel.

Patient EducationClinical

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 D58.2Overview

What is the ICD-10 code for other hemoglobinopathies?

The ICD-10-CM code for other hemoglobinopathies is D58.2 (sometimes written as D582). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Is D58.2 (Other hereditary hemolytic anemias) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other hemoglobinopathies on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does D58.2 group to?

When other hemoglobinopathies is the principal diagnosis on an inpatient stay, it groups to MS-DRG 811, 812, with relative weights from 0.9182 to 1.4043 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of D58.2?

Under the General Equivalence Mappings, other hemoglobinopathies converts to ICD-9-CM 282.7 (hemoglobinopathies NEC). The mapping is approximate, so confirm the match fits the documentation.

Does D58.2 risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. D58.2 mapped to HCC 48 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 48 (Coagulation Defects and Other Specified Hematological Disorders), ESRD (V21) category 48 (Coagulation Defects and Other Specified Hematological Disorders), and ESRD (V24) category 48 (Coagulation Defects and Other Specified Hematological Disorders).
