Y37.4 — Military operations involving firearm discharge and other forms of conventional warfare
Y37.4 is a non-billable header ICD-10-CM code for military 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.

Risk adjustment
Y37.4 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.
