Vertigo from infrasound, initial encounter

This code signifies a patient experiencing a sensation of spinning or imbalance specifically caused by exposure to infrasound. Infrasound refers to sound waves with frequencies below the lower limit of human audibility, which can induce physiological effects like vertigo. This diagnosis indicates the initial presentation of such symptoms.

Use this code when documenting a patient's first encounter for vertigo directly attributed to infrasound exposure. This might occur after exposure to industrial machinery, natural phenomena like strong winds, or certain types of audio equipment. It's appropriate when the infrasound is identified as the primary cause of the vestibular disturbance.

• Ensure documentation clearly links the vertigo to infrasound exposure.
• Verify this is the patient's first time seeking treatment for this specific condition.
• Consider additional codes for any associated symptoms or underlying conditions if present.
