Reverse articulation

This code describes a malocclusion where the anterior teeth (incisors) or posterior teeth (molars/premolars) are in an abnormal relationship, with the maxillary teeth positioned lingually to the mandibular teeth. This is commonly known as an anterior or posterior crossbite. It indicates a deviation from the normal intercuspation of the opposing dental arches.

Use this code when documentation specifies an anterior or posterior crossbite, or explicitly states "reverse articulation" in the context of a malocclusion. This diagnosis is typically made during an orthodontic or dental examination based on clinical observation and possibly dental models or radiographs.

• Differentiate between anterior and posterior reverse articulation if specified in the documentation.
• Do not confuse with other malocclusion types like overbite or underbite, unless a crossbite is also present.
• Consider additional codes for associated dental anomalies or underlying skeletal discrepancies if documented.
