Machinery accident on board unspecified watercraft, sequela

This code describes a long-term health condition or complication resulting from an injury sustained due to a machinery accident on any type of watercraft where the specific type of vessel is not documented. It indicates that the initial injury has healed, but its lasting effects are still present and require ongoing medical attention.

This code is appropriate for documenting residual conditions, such as chronic pain, limited range of motion, or neurological deficits, directly attributable to a past machinery accident on an unspecified watercraft. It should be used when the patient is presenting for treatment of these sequelae, not for the initial acute injury.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past machinery accident on a watercraft.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code with an external cause code.
