Non-billable headerICD-10-CM

The appropriate 7th character is to be added to each code from category Y35

Includes

Conditions this code covers.

any injury sustained as a result of an encounter with any law enforcement official, serving in any capacity at the time of the encounter, whether on-duty or off-duty. Includes: injury to law enforcement official, suspect and bystander

Other codes that can never be billed with Y35

These codes carry an Excludes1 note pointing at Y35. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y35 alone.

W32Accidental handgun discharge and malfunction
W33Accidental rifle, shotgun and larger firearm discharge and malfunction
W40Explosion of other materials
W40.8Explosion of other specified explosive materials
W40.8XXAExplosion of other specified explosive materials, initial encounter
W40.8XXDExplosion of other specified explosive materials, subsequent encounter
W40.8XXSExplosion of other specified explosive materials, sequela

Y35 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 Y35

7 child codes. Green means billable.
