X03.1 — Exposure to smoke in controlled fire, not in building or structure
Is X03.1 billable?

Excludes1 — never code together — inherited from X00-X08
The conditions below can never be reported together with X03.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- arson (X97)
Excludes2 — not included here — inherited from X00-X08
The conditions below are not part of X03.1, but a patient may have both at the same time. When documentation supports it, X03.1 and the excluded code may both be reported.
