Explosion on board passenger ship, subsequent encounter

This code signifies a patient presenting for follow-up care, rehabilitation, or management of long-term effects stemming from injuries sustained during an explosion on a passenger ship. It indicates that the initial acute event has passed, and the patient is now receiving ongoing treatment related to that specific incident.

Apply this code for patients returning for subsequent appointments after the initial treatment of injuries from a passenger ship explosion. This includes visits for physical therapy, wound care, psychological counseling, or evaluation of chronic conditions directly attributable to the explosion.

• Ensure documentation clearly states the encounter is for follow-up care related to the initial explosion.
• Always pair this external cause code with a primary diagnosis code detailing the specific injury or condition being treated.
• Verify the "D" seventh character is appropriate for subsequent encounters, indicating healing or recovery is underway.
