Unspecified anomaly of dental arch relationship

This code represents an unspecific deviation or malformation in how the upper and lower dental arches align or relate to each other. It indicates a general issue with the bite or jaw relationship without specifying the exact nature of the anomaly. This could include problems with overbite, underbite, crossbite, or open bite, where the specific type is not documented.

Use this code when the provider's documentation indicates a dental arch relationship anomaly, but the specific type (e.g., Angle's Class I, II, or III malocclusion, open bite, deep bite) is not clearly identified. It is appropriate when the diagnosis is broad or preliminary, and further specificity is not yet determined or recorded. Documentation should explicitly state an "anomaly of dental arch relationship" without further detail.

• Avoid using this code if more specific documentation regarding the type of malocclusion (e.g., M26.21-M26.29) is available.
• Query the provider for more specific details if the documentation only states "malocclusion" or "bite problem" to determine if a more precise code can be assigned.
• This code should be sequenced as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-existing condition.
