Contact w explosive material, undetermined intent, sequela

This code signifies a long-term health condition or complication arising from an individual's past exposure to explosive material, where the circumstances surrounding that exposure (e.g., accidental, intentional self-harm, assault) could not be determined. It indicates that the original event's intent remains unknown, and the patient is now presenting with a residual effect.

Apply this code when a patient presents with a sequela (e.g., chronic pain, scarring, hearing loss, psychological trauma) directly attributable to a prior contact with explosive material, and medical records lack sufficient information to definitively classify the intent of the original incident. This is used for conditions that manifest after the acute phase of the injury has passed.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., T90.5XXS for sequela of eye injury).
• Ensure documentation clearly links the current condition to a past exposure to explosive material with undetermined intent.
• Do not use this code for acute injuries; it is exclusively for residual effects or complications.
