Other codes that can never be billed with O9A.4

These codes carry an Excludes1 note pointing at O9A.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O9A.4 alone.

  • T74Adult and child abuse, neglect and other maltreatment, confirmed
  • T76Adult and child abuse, neglect and other maltreatment, suspected

Risk adjustment

O9A.4 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 O9A.4
