W22 — Striking against or struck by other objects
W22 is a non-billable header ICD-10-CM code for striking against or struck by other objects. 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 W22
- 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.
- striking against or struck by object with subsequent fall (W18.09)
Other codes that can never be billed with W22
These codes carry an Excludes1 note pointing at W22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W22 alone.
- W50Accidental hit, strike, kick, twist, bite or scratch by another person
- W67Accidental drowning and submersion while in swimming-pool
- W67.XXXAAccidental drowning and submersion while in swimming-pool, initial encounter
- W67.XXXDAccidental drowning and submersion while in swimming-pool, subsequent encounter
- W67.XXXSAccidental drowning and submersion while in swimming-pool, sequela
Risk adjustment
W22 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 W22
3 child codes. Green means billable.
