About D57.41

D57.41 is the ICD-10-CM diagnosis code for sickle-cell thalassemia, unspecified, with crisis. It belongs to category D57 (sickle-cell disorders), 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 a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within D57.4, choose D57.41 (unspecified, with crisis) only when documentation doesn't support a more specific option: without crisis (D57.40), beta zero without crisis (D57.42), beta zero with crisis (D57.43), beta plus without crisis (D57.44) and beta plus with crisis (D57.45).

To report this condition, pick the subcode that matches the documentation: D57.411 (syndrome), D57.412 (sequestration), D57.413 (involvement), D57.414 (dactylitis), D57.418 (with other specified complication) and D57.419 (crisis).

Use an additional code for any associated fever (R50.81).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (title revised).
