W30Contact with agricultural machinery

W30 is the ICD-10-CM diagnosis code for contact with agricultural machinery. It belongs to block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: W30.0 (harvester), W30.1 ((PTO)), W30.2 (derrick), W30.3 (elevator), W30.8 (machinery) and W30.9 (machinery).

Don't report W30 together with the conditions in its Excludes1 note: agricultural transport vehicle accident (V01-V99), explosion of grain store (W40.8) and exposure to electric current (W86.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
