About coding trait sickle-cell
The ICD-10-CM code for trait sickle-cell is D57.3 (Sickle-cell trait).
Within D57 (sickle-cell disorders), D57.3 is specifically for sickle-cell trait. Related codes cover Hb-SS disease with crisis (D57.0), sickle-cell disease without crisis (D57.1), Sickle-cell/Hb-C disease (D57.2), sickle-cell thalassemia (D57.4) and other sickle-cell disorders (D57.8).
Use an additional code for any associated fever (R50.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
