Not billable

Is X00 billable?

No — X00 is a non-billable header code. X00 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 21 billable codes beneath X00.

  • any associated cataclysm

Excludes2 — not included here

The conditions below are not part of X00, but a patient may have both at the same time. When documentation supports it, X00 and the excluded code may both be reported.

  • Exposure to ignition or melting of nightwear (X05)
  • Exposure to ignition or melting of other clothing and apparel (X06.-)
  • Exposure to other specified smoke, fire and flames (X08.-)

Conditions classified to X00.

  • conflagration in building or structure

Excludes1 — never code together — inherited from X00-X08

The conditions below can never be reported together with X00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes2 — not included here — inherited from X00-X08

The conditions below are not part of X00, but a patient may have both at the same time. When documentation supports it, X00 and the excluded code may both be reported.

  • explosions (W35-W40)
  • lightning (T75.0-)
  • transport accident (V01-V99)
