Excludes1 inherited from the categories above T74.31

These are not written on T74.31, but they bind it: a note on a category applies to every code beneath it. Billing T74.31 with anything listed here is a denial.

Written on T74 — Adult and child abuse, neglect and other maltreatment, confirmed

abuse and maltreatment in pregnancy (O9A.3-, O9A.4-, O9A.5-)
adult and child maltreatment, suspected (T76.-)

Other codes that can never be billed with T74.31

These codes carry an Excludes1 note pointing at T74.31. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T74.31 alone.

Z04.71Encounter for examination and observation following alleged adult physical abuse
Z04.72Encounter for examination and observation following alleged child physical abuse
T76Adult and child abuse, neglect and other maltreatment, suspected

Risk adjustment

T74.31 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.
