About W29.8XXA
W29.8XXA is the ICD-10-CM diagnosis code for contact with other powered hand tools and household machinery, initial encounter. It belongs to category W29 (contact with other powered hand tools and household machinery), block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "A" means initial encounter: use it while the patient is receiving active treatment for the condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (title revised).
Before ICD-10, this condition was coded in ICD-9-CM as E920.1 (accidents caused by other powered hand tools).
