W49 — Exposure to other inanimate mechanical forces
Is W49 billable?
No — W49 is a non-billable header code. W49 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 18 billable codes beneath W49.

Conditions classified to W49.
- exposure to abnormal gravitational [G] forces
- exposure to inanimate mechanical forces NEC
Excludes1 — never code together — inherited from W20-W49
The conditions below can never be reported together with W49 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
