T80.3

T80.3 — ABO incompatibility reaction due to transfusion of blood or blood products

Non-billable headerICD-10-CM

T80.3 is a non-billable header ICD-10-CM code for abo incompatibility reaction due to transfusion of blood or blood products. 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.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category T80

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1 — never code together

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

minor blood group antigens reactions (Duffy) (E) (K) (Kell) (Kidd) (Lewis) (M) (N) (P) (S) (T80.A-)

Other codes that can never be billed with T80.3

These codes carry an Excludes1 note pointing at T80.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T80.3 alone.

T80.5Anaphylactic reaction due to serum
T80.91Hemolytic transfusion reaction, unspecified incompatibility

Risk adjustment

T80.3 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 T80.3

3 child codes. Green means billable.
