X05 — Exposure to ignition or melting of nightwear
Is X05 billable?
No — X05 is a non-billable header code. X05 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 3 billable codes beneath X05.

Excludes2 — not included here
The conditions below are not part of X05, but a patient may have both at the same time. When documentation supports it, X05 and the excluded code may both be reported.
- exposure to uncontrolled fire in building or structure (X00.-)
- exposure to uncontrolled fire, not in building or structure (X01.-)
- exposure to controlled fire in building or structure (X02.-)
- exposure to controlled fire, not in building or structure (X03.-)
- exposure to ignition of highly flammable materials (X04.-)
Excludes1 — never code together — inherited from X00-X08
The conditions below can never be reported together with X05 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 X05, but a patient may have both at the same time. When documentation supports it, X05 and the excluded code may both be reported.
