Anomalies of dental arch relationship
Anomalies of dental arch relationship
M26.2 is a header (parent) code in the ICD-10-CM hierarchy. It is not billable for claim submission. Use one of the billable child codes listed below.
Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
M26.20 captures a dental arch relationship anomaly that has been identified clinically but not further characterized — use it only when documentation lacks the specificity required by any sibling code under M26.2.
M26.23 identifies an excessive horizontal overlap of the teeth — clinically termed overjet — where the upper incisors protrude too far horizontally beyond the lower incisors. This is the coding equivalent of what is colloquially called a 'horizontal overbite' or Angle Class II, Division 1 malocclusion.
M26.24 classifies reverse articulation — a dental arch relationship anomaly in which the normal occlusal relationship is reversed, including anterior and posterior crossbite.
M26.25 identifies a dentofacial anomaly in which the vertical or horizontal distance between the maxillary and mandibular dental arches deviates from accepted norms, affecting occlusal relationships and jaw function.
M26.29 captures dental arch relationship anomalies that don't fit any more specific subcategory under M26.2 — including midline deviation of the dental arch, excessive deep/horizontal/vertical overbite, and posterior lingual occlusion of mandibular teeth.
