Struck by falling object on merchant ship, subs encntr

This code indicates that a patient experienced an injury due to being hit by a falling object while aboard a merchant ship. This specific encounter is for follow-up care after the initial treatment for the injury has already been provided. The injury could range from minor contusions to more severe trauma.

Use this code for any subsequent visits related to an injury sustained from a falling object on a merchant ship, such as wound checks, physical therapy, or medication adjustments. This applies after the acute phase of care has concluded and the patient is returning for ongoing management. Do not use for the initial treatment of the injury.

• Always pair with an external cause code (e.g., W20.XXX) to specify the nature of the falling object.
• Ensure the "D" seventh character is appropriate for subsequent encounters; "A" is for initial, "S" for sequela.
• Verify the encounter type aligns with follow-up care, not the initial presentation of the injury.
