Motion sickness, initial encounter

This code signifies the initial presentation of symptoms related to motion sickness, a common disorder of the inner ear characterized by nausea, vomiting, dizziness, and sweating, triggered by motion. It results from a mismatch between sensory inputs from the eyes, inner ear, and proprioceptors.

Apply this code for a patient's first documented encounter for motion sickness, such as a new diagnosis during a routine physical or an urgent care visit for acute symptoms experienced for the first time. This includes instances where a patient presents with classic symptoms after travel by car, boat, or airplane.

• Ensure documentation clearly states this is the patient's first episode or initial presentation for this condition.
• Do not use this code for subsequent encounters for motion sickness; a different seventh character will be required.
• Consider co-occurring symptoms like nausea or vomiting, but the primary diagnosis should reflect the motion sickness itself.
