Helicopter explosion injuring occupant, sequela

This code signifies a long-term health condition or complication resulting from an occupant being injured in a helicopter explosion. It indicates that the initial traumatic event has led to persistent issues requiring ongoing medical attention or management.

Apply this code when documenting a current health problem directly attributable to a past helicopter explosion injury sustained by an occupant. This is appropriate for follow-up encounters where the sequela of the original injury is being treated, such as chronic pain, neurological deficits, or scar contractures.

• Always sequence this code after the code(s) identifying the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past helicopter explosion.
• Do not use this code for the initial acute injury; it is exclusively for residual effects.
