Y22 — Handgun discharge, undetermined intent
Y22 is a non-billable header ICD-10-CM code for handgun discharge, undetermined intent. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Alternative wordings a physician may use in the chart for this same code.

Risk adjustment
Y22 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How Y22 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Y22.

- Undetermined intent›firearm discharge›handgun(pistol) (revolver)
- Discharge›firearm›handgun›stated as undetermined whether accidental or intentional
