About V91.23XA
V91.23XA is the ICD-10-CM diagnosis code for fall due to collision between other powered watercraft and other watercraft or other object, initial encounter. It belongs to category V91 (other injury due to accident to watercraft), block V90-V94 (water transport accidents) 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 E831.9 (accident to watercraft causing other injury to unspecified person).
