Burn due to localized fire on board unsp watercraft, subs

This code signifies a burn injury sustained from a localized fire on any type of watercraft, where the patient is receiving follow-up care for that specific injury. The fire source is confined, not a general conflagration of the vessel. This code is used after the initial treatment of the burn.

Apply this code for patients presenting for subsequent care of a burn injury, such as wound checks, dressing changes, or debridement, that was originally caused by a contained fire on a boat, ship, or other water vessel. This includes scenarios where the specific type of watercraft is not documented.

• Requires an external cause code (V93.09) to specify the mechanism of injury.
• Always sequence after the burn code (T20-T31) to provide context for the injury.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine follow-up care.
