Non-billable headerICD-10-CM

W03 is a non-billable header ICD-10-CM code for other fall on same level due to collision with another person. 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.

The appropriate 7th character is to be added to code W03

  • fall involving pedestrian conveyance (V00-V09)
  • fall due to ice or snow (W00)
