What this code represents

The code Y25.XXXD represents a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase after the active treatment phase for the explosive contact injury has ended. 2

This diagnosis code falls under the parent concept Y25, which broadly categorizes contact with explosive material of undetermined intent within the ICD-10-CM terminology structure. 1

Coding details

For external cause codes, the seventh character D identifies a subsequent encounter, distinguishing it from character A for initial encounters and character S for sequelae in the ICD-10-CM coding system. 2

The terminology record for Y25.XXXD lists an alternative published abbreviation as contact with explosive material, undetermined intent, subs, and confirms the concept has narrower child concepts. 1 4

Documentation considerations

When the intent of an injury is not known or not well documented in the medical record, ICD-10-CM codes for undetermined intent, such as Y25.XXXD, may be assigned to capture the event. 2

What the sources add

While the terminology record defines the code hierarchy and semantic type, the national health statistics report adds operational context by explaining how the seventh character D designates the recovery phase for external cause codes. 1 2
