Excludes1 inherited from the categories above T80.39XA

These are not written on T80.39XA, but they bind it: a note on a category applies to every code beneath it. Billing T80.39XA with anything listed here is a denial.

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

Excludes2 inherited from the categories above T80.39XA

Also inherited, and the opposite of Excludes1: these conditions are not part of T80.39XA, but a patient can have both, so you may code both.

bone marrow transplant rejection (T86.01)
febrile nonhemolytic transfusion reaction (R50.84)
fluid overload due to transfusion (E87.71)

Risk adjustment

T80.39XA 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.

Medicare coverage

T80.39XA is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
