Not billable

Is W34 billable?

No — W34 is a non-billable header code. W34 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 30 billable codes beneath W34.

Excludes1 — never code together — inherited from W20-W49

The conditions below can never be reported together with W34 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • assault (X92-Y09)
  • contact or collision with animals or persons (W50-W64)
  • exposure to inanimate mechanical forces involving military or war operations (Y36.-, Y37.-)
  • intentional self-harm (X71-X83)
