X03 — Exposure to controlled fire, not in building or structure
Is X03 billable?
No — X03 is a non-billable header code. X03 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 15 billable codes beneath X03.

Excludes1 — never code together — inherited from X00-X08
The conditions below can never be reported together with X03 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, but a patient may have both at the same time. When documentation supports it, X03 and the excluded code may both be reported.
