Terorsm w explosn of marine weapons, civilian injured, subs

This code signifies an injury sustained by a civilian due to a terrorist act involving the detonation of marine-based weaponry, such as mines or torpedoes. The "subsequent encounter" indicates that this code is used for follow-up care, rehabilitation, or management of complications related to the initial injury.

Apply this code when a civilian patient presents for ongoing treatment of injuries (e.g., blast injuries, shrapnel wounds, burns) that were originally caused by a terrorist explosion of marine weapons. This includes visits for physical therapy, wound care, or surgical revisions after the initial acute care phase.

• Ensure documentation clearly states the injury resulted from a terrorist act involving marine weapons.
• Verify the encounter is for follow-up care, not the initial treatment.
• Always code the specific injury(ies) first, then append this external cause code.
