War op w explosn of sea-based artlry shell, civilian, subs

This code signifies an injury or health condition sustained by a civilian due to the delayed effects or follow-up care related to an explosion of an artillery shell that occurred in a sea-based war operation. It indicates that the patient is presenting for care after the initial treatment of the injury.

This code is appropriate for documenting subsequent encounters for a civilian patient who was injured by a sea-based artillery shell explosion during war operations. Examples include follow-up appointments for wound care, rehabilitation, or management of chronic conditions resulting from the initial blast. It should be used when the patient is no longer in the acute phase of injury.

• Ensure the patient is explicitly documented as a civilian and the incident involved a sea-based artillery shell explosion during war operations.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the specific injury or condition resulting from the explosion first, followed by this external cause code.
