T80.910Acute hemolytic transfusion reaction, unspecified incompatibility

Non-billable headerICD-10-CM

T80.910 is a non-billable header ICD-10-CM code for acute hemolytic transfusion reaction, unspecified incompatibility. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Excludes1 inherited from the categories above T80.910

These are not written on T80.910, but they bind it: a note on a category applies to every code beneath it. Billing T80.910 with anything listed here is a denial.

Written on T80.91 Hemolytic transfusion reaction, unspecified incompatibility

  • ABO incompatibility with hemolytic transfusion reaction (T80.31-)
  • Non-ABO incompatibility with hemolytic transfusion reaction (T80.A1-)
  • Rh incompatibility with hemolytic transfusion reaction (T80.41-)

Excludes2 inherited from the categories above T80.910

Also inherited, and the opposite of Excludes1: these conditions are not part of T80.910, but a patient can have both, so you may code both.

Written on T80 Complications following infusion, transfusion and therapeutic injection

  • bone marrow transplant rejection (T86.01)
  • febrile nonhemolytic transfusion reaction (R50.84)
  • fluid overload due to transfusion (E87.71)
  • posttransfusion purpura (D69.51)
  • transfusion associated circulatory overload (TACO) (E87.71)
  • transfusion (red blood cell) associated hemochromatosis (E83.111)
  • transfusion related acute lung injury (TRALI) (J95.84)

Risk adjustment

T80.910 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.

How T80.910 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to T80.910.

Questions about T80.910

Is T80.910 a billable ICD-10-CM code?
No. T80.910 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
Where does T80.910 sit in the tabular list?
Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Complications of surgical and medical care, not elsewhere classified (T80-T88).
What cannot be coded together with T80.910?
T80.910 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above T80.910 (T80.91) and apply to it just the same.
