Exposure to ignition of highly flammable material (X04)

ICD-10 code X04 is used to classify injuries resulting from exposure to the ignition of highly flammable materials. This includes various scenarios where substances like gasoline, kerosene, or liquid paraffin catch fire, often leading to burns or related injuries.

These codes cover different stages of care: X04.XXXA denotes the initial encounter with injuries caused by ignition of highly inflammable materials, such as accidental fires involving clothing or household liquid paraffin gas cookers. The code X04.XXXD applies to subsequent encounters during ongoing treatment, while X04.XXXS records sequela, or complications and late effects, from the original exposure. Using synonyms like “ignition of benzine with ignition of clothing” or “ignition of paraffin with ignition of clothing” helps clarify that these codes specifically address accidental fire exposures to materials that catch fire easily, aiding medical coders in selecting the precise code for such incidents. Understanding the correct use of ICD-10 code for exposure to ignition of highly flammable material ensures accurate documentation of these unique external causes of injury.

Instructional Notations

Inclusion Terms

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

  • Exposure to ignition of gasoline
  • Exposure to ignition of kerosene
  • Exposure to ignition of petrol

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • exposure to ignition or melting of nightwear X05
  • exposure to ignition or melting of other clothing and apparel X06

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to code X04

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.
