D57 — Sickle-cell disorders

Non-billable headerICD-10-CM

D57 is a non-billable header ICD-10-CM code for sickle-cell disorders. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

other hemoglobinopathies (D58.-)

Use additional code

Add a secondary code to capture the detail described below.

code for any associated fever (R50.81)

Other codes that can never be billed with D57

These codes carry an Excludes1 note pointing at D57. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D57 alone.

D56.1Beta thalassemia
D56.3Thalassemia minor
D56.5Hemoglobin E-beta thalassemia
D56.8Other thalassemias

Risk adjustment

D57 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.

Code to one of these instead D57

6 child codes. Green means billable.
