Other codes that can never be billed with Y36.5
These codes carry an Excludes1 note pointing at Y36.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y36.5 alone.
- Y36.2War operations involving other explosions and fragments
- Y36.3War operations involving fires, conflagrations and hot substances
- Y36.7War operations involving chemical weapons and other forms of unconventional warfare
- Y37.3Military operations involving fires, conflagrations and hot substances
- Y37.7Military operations involving chemical weapons and other forms of unconventional warfare
Risk adjustment
Y36.5 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.
