  • Delayed serologic transfusion reaction (DSTR) from ABO incompatibility
  • Other ABO incompatible blood transfusion
  • Other reaction to ABO incompatible blood transfusion

Risk adjustment

T80.39 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.
