X97 — Assault by smoke, fire and flames
X97 is a non-billable header ICD-10-CM code for assault by smoke, fire and flames. 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.

Other codes that can never be billed with X97
These codes carry an Excludes1 note pointing at X97. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X97 alone.
- X96Assault by explosive material
Risk adjustment
X97 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 X97 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 X97.
