About W27.8XXA
W27.8XXA is the ICD-10-CM diagnosis code for contact with other nonpowered hand tool, initial encounter. It belongs to category W27 (contact with nonpowered hand tool), 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 hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E920.4 (accidents caused by other hand tools and implements).
