Motion sickness

This code represents a physiological response to real or perceived motion, characterized by symptoms such as nausea, vomiting, dizziness, and pallor. It occurs when there is a conflict between sensory inputs from the inner ear, eyes, and proprioceptors regarding body movement.

Use this code for patients presenting with symptoms specifically attributed to motion sickness, whether from travel (e.g., car, boat, plane) or other motion-inducing activities. Documentation should clearly indicate the patient's symptoms are a direct result of motion exposure.

• Do not use this code for vertigo or dizziness from other causes; those have specific codes.
• Consider an E-code if the motion sickness is related to a specific type of transport accident (e.g., E845.9 for other specified watercraft accident).
• This is typically a primary diagnosis unless it's a transient symptom during an encounter for a different, unrelated condition.
