X00.8XXA — Other exposure to uncontrolled fire in building or structure, initial encounter
X00.8XXA is a billable, specific ICD-10-CM code for other exposure to uncontrolled fire in building or structure, initial encounter. It is valid for submission on a claim.

- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes2 inherited from the categories above X00.8XXA
Also inherited, and the opposite of Excludes1: these conditions are not part of X00.8XXA, but a patient can have both, so you may code both.
Other codes that can never be billed with X00.8XXA
These codes carry an Excludes1 note pointing at X00.8XXA. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X00.8XXA alone.

- W13.9XXDFall from, out of or through building, not otherwise specified, subsequent encounter

Risk adjustment
X00.8XXA 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.
Code history
X00.8XXA has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
