Lack of posterior occlusal support

This code describes a condition where there is insufficient posterior tooth contact, leading to an unstable bite. This can result from missing posterior teeth, supra-erupted opposing teeth, or malocclusion, impacting masticatory function and potentially causing temporomandibular joint (TMJ) issues.

Apply this code when documentation indicates a patient presents with an absence or inadequacy of posterior occlusal stops. This is commonly seen in cases of partial edentulism, collapsed bites, or significant wear of posterior dentition. Supporting documentation should clearly state the lack of posterior support and its clinical implications.

• Specify the affected arch (e.g., maxillary, mandibular) if documented, though this code is general.
• Consider co-reporting with codes for missing teeth (K08.1-) or other occlusal anomalies (K07.-) if applicable.
• Ensure the documentation distinguishes this from general malocclusion without specific reference to posterior support.
