Y36.4 — War operations involving firearm discharge and other forms of conventional warfare
Y36.4 is a non-billable header ICD-10-CM code for war operations involving firearm discharge and other forms of conventional warfare. 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.

These codes carry an Excludes1 note pointing at Y36.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y36.4 alone.
Risk adjustment
Y36.4 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.
