Excessive interocclusal distance of fully erupted teeth

This code describes a condition where there is an abnormally large vertical gap between the biting surfaces of the upper and lower teeth when the jaw is in its resting position. This excessive space, also known as freeway space, can indicate an underlying occlusal disharmony or malocclusion. It often presents with symptoms related to mastication, speech, or temporomandibular joint (TMJ) dysfunction.

Apply this code when documentation specifies an excessive interocclusal distance in a patient whose permanent teeth have fully erupted. This typically occurs when the vertical dimension of occlusion is insufficient. Supporting documentation should include clinical measurements, dental examination findings, and a clear diagnosis of excessive interocclusal distance.

• Differentiate from other malocclusion codes; this specifically refers to the vertical dimension of the resting occlusion.
• Ensure the documentation confirms "fully erupted teeth" to avoid coding for developing dentition.
• Consider sequencing this code with other codes describing associated symptoms or underlying causes of the malocclusion.
