W05 — Fall from non-moving wheelchair, nonmotorized scooter and motorized mobility scooter

Non-billable headerICD-10-CM

W05 is a non-billable header ICD-10-CM code for fall from non-moving wheelchair, nonmotorized scooter and motorized mobility scooter. 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 W05

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 from moving wheelchair (powered) (V00.811)
fall from moving motorized mobility scooter (V00.831)
fall from nonmotorized scooter (V00.141)

Other codes that can never be billed with W05

These codes carry an Excludes1 note pointing at W05. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W05 alone.

V00Pedestrian conveyance accident
V00.811Fall from moving wheelchair (powered)

V00.811SFall from moving wheelchair (powered), sequela
V00.831AFall from motorized mobility scooter, initial encounter
V00.831DFall from motorized mobility scooter, subsequent encounter

Risk adjustment

W05 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 W05

3 child codes. Green means billable.
