Is W03 a billable ICD-10-CM code?

No. W03 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does W03 sit in the tabular list?

External causes of morbidity (V00-Y99), in the block Slipping, tripping, stumbling and falls (W00-W19).

What cannot be coded together with W03?

W03 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

W03 — Other fall on same level due to collision with another person

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.

This code requires a 7th character

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

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.

collision with another person without fall (W51)
crushed or pushed by a crowd or human stampede (W52)
fall involving pedestrian conveyance (V00-V09)
fall due to ice or snow (W00)
fall on same level NOS (W18.30)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Fall due to non-transport collision with other person

Other codes that can never be billed with W03

These codes carry an Excludes1 note pointing at W03. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W03 alone.

V00Pedestrian conveyance accident
W51Accidental striking against or bumped into by another person
W51.XXXAAccidental striking against or bumped into by another person, initial encounter
W51.XXXDAccidental striking against or bumped into by another person, subsequent encounter
W51.XXXSAccidental striking against or bumped into by another person, sequela

Risk adjustment

W03 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.

How W03 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to W03.
