D58.2 — Other hemoglobinopathies

Billable / specific codeICD-10-CM

D58.2 is a billable, specific ICD-10-CM code for other hemoglobinopathies. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

familial polycythemia (D75.0)
Hb-M disease (D74.0)
hemoglobin E-beta thalassemia (D56.5)
hereditary persistence of fetal hemoglobin [HPFH] (D56.4)
high-altitude polycythemia (D75.1)
methemoglobinemia (D74.-)
other hemoglobinopathies with thalassemia (D56.8)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Abnormal hemoglobin NOS
Congenital Heinz body anemia
Hb-C disease
Hb-D disease
Hb-E disease
Hemoglobinopathy NOS
Unstable hemoglobin hemolytic disease

Other codes that can never be billed with D58.2

These codes carry an Excludes1 note pointing at D58.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D58.2 alone.

D56.5Hemoglobin E-beta thalassemia
D56.8Other thalassemias

Risk adjustment

D58.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

D58.2 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
