Contact with explosive material, undetermined intent (Y25)

The ICD-10 code Y25 is used for documenting cases where a person has had contact with explosive material but the intent behind the incident is not clearly known. This code helps record injuries from explosions when it’s unclear if they were accidental or intentional.

The code set under Y25 includes specific designations like Y25.XXXA for initial encounters, Y25.XXXD for subsequent medical visits, and Y25.XXXS for sequela, which refers to complications or conditions following the original injury. These codes are commonly linked to terms such as "injury of unknown intent by explosives" or "injury due to explosive weapon," helping coders assign the right code even when the cause is uncertain. This category is important for medical professionals and coders to accurately classify injuries related to explosives when intent cannot be determined, supporting detailed medical records and appropriate care follow-up.

Instructional Notations

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.
