About Y24.0XXA
Y24.0XXA is the ICD-10-CM diagnosis code for airgun discharge, undetermined intent, initial encounter. It belongs to category Y24 (other and unspecified firearm discharge, undetermined intent), block Y21-Y33 (event of undetermined intent) 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 E985.6 (injury by air gun, undetermined whether accidental or purposely inflicted).
