Explosion of other specified explosive materials, sequela

This code signifies a long-term or late-occurring health condition resulting from an explosion involving explosive materials other than fireworks, firearms, or other specified types. These sequelae are the residual effects of the initial injury, which may manifest months or years after the original explosive event.

Use this code when documenting chronic pain, scarring, neurological deficits, hearing loss, or psychological trauma that is directly attributable to an explosion of unspecified explosive materials. This code is appropriate for follow-up encounters where the initial injury has healed, but its lasting consequences are being treated or monitored.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure the medical record clearly links the current condition to the past explosion event.
• Do not use this code for acute injuries from an explosion; use the appropriate acute injury code with the initial encounter or subsequent encounter seventh character.
