Machinery accident on board merchant ship, subs encntr

This code indicates a patient presenting for follow-up care, such as wound checks, physical therapy, or medication adjustments, due to an injury sustained from machinery while on a merchant ship. The initial injury has already been treated, and this encounter addresses ongoing management or complications.

Apply this code for any subsequent visit related to an injury that occurred due to machinery on a merchant vessel. This includes encounters for rehabilitation, monitoring of healing, or treatment of delayed complications following the initial acute care. Do not use for the initial treatment of the injury.

• Always pair with an external cause code (V00-Y99) to specify the nature of the injury.
• Ensure the "D" seventh character is appropriate for subsequent encounters; avoid "A" (initial) or "S" (sequela).
• Verify the accident occurred on a "merchant ship" as opposed to other types of watercraft.
