About W30.9

W30.9 is the ICD-10-CM diagnosis code for contact with unspecified agricultural machinery. It belongs to category W30 (contact with agricultural machinery), 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 3 subcodes must be used instead.

Within W30, choose W30.9 (unspecified agricultural machinery) only when documentation doesn't support a more specific option: combine harvester (W30.0), power take-off devices (PTO) (W30.1), hay derrick (W30.2), grain storage elevator (W30.3) and other specified agricultural machinery (W30.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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