W18.0 — Fall due to bumping against object
W18.0 is a non-billable header ICD-10-CM code for fall due to bumping against object. 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 W18
- 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.
- fall on same level due to slipping, tripping, or stumbling with subsequent striking against object (W01.1-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Striking against object with subsequent fall
Other codes that can never be billed with W18.0
These codes carry an Excludes1 note pointing at W18.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W18.0 alone.
- W01Fall on same level from slipping, tripping and stumbling
- W21Striking against or struck by sports equipment
- W22Striking against or struck by other objects
- W25Contact with sharp glass
- W25.XXXAContact with sharp glass, initial encounter
- W25.XXXDContact with sharp glass, subsequent encounter
- W25.XXXSContact with sharp glass, sequela
Risk adjustment
W18.0 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 W18.0
4 child codes. Green means billable.
