Hit by falling object due to accident to merchant ship, subs

This code describes an injury sustained by an individual who was hit or struck by a falling object during an accident involving a merchant ship. It specifically indicates that this is not the initial encounter for this injury, meaning the patient is receiving follow-up care or treatment for complications arising from the original incident.

Use this code for subsequent encounters when a patient presents for ongoing treatment, evaluation of healing, or management of delayed complications related to an injury sustained from a falling object on a merchant ship. This includes scenarios like follow-up appointments for fractures, wound care, or physical therapy after the initial emergency treatment.

• Ensure documentation clearly states the patient is receiving follow-up care for an injury from a falling object on a merchant ship.
• Verify the encounter is not the initial treatment for the injury; if it is, a different encounter character (A) would be used.
• Always code additional external cause codes (e.g., W20.XXXD for struck by falling object) to provide a complete picture of the incident.
