Motion sickness, sequela

This code signifies the long-term or residual effects resulting from a past episode of motion sickness. These sequelae are persistent symptoms or conditions that developed as a direct consequence of the original motion sickness event, rather than the acute episode itself.

Apply this code when documenting chronic or lasting symptoms attributable to a previous bout of motion sickness, such as persistent anxiety related to travel, phobias developed after severe motion sickness, or other ongoing psychological or physiological impacts. It should be used after the acute phase of motion sickness has resolved, and the current encounter addresses these lasting effects.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past episode of motion sickness.
• This code is for the sequela only; do not use it for acute or current motion sickness episodes.
