Y36 — Operations of war
Y36 is a non-billable header ICD-10-CM code for operations of war. 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.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category Y36
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Includes
Conditions this code covers.
- injuries to military personnel and civilians caused by war, civil insurrection, and peacekeeping missions
Other codes that can never be billed with Y36
These codes carry an Excludes1 note pointing at Y36. 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 alone.
- V90Drowning and submersion due to accident to watercraft
- V91Other injury due to accident to watercraft
- V92Drowning and submersion due to accident on board watercraft, without accident to watercraft
- V93Other injury due to accident on board watercraft, without accident to watercraft
- V94Other and unspecified water transport accidents
- W32Accidental handgun discharge and malfunction
- W33Accidental rifle, shotgun and larger firearm discharge and malfunction
- W40Explosion of other materials
Risk adjustment
Y36 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.
