Insufficient anterior guidance

This code describes a malocclusion where the anterior teeth do not adequately guide the mandible during excursive movements, leading to posterior tooth interference. This lack of proper anterior disclusion can result in excessive forces on posterior teeth, contributing to wear, mobility, or temporomandibular joint (TMJ) dysfunction.

Use this code when documentation explicitly states "insufficient anterior guidance" or describes a lack of anterior disclusion during eccentric movements. This often occurs in the context of occlusal analysis, restorative dentistry planning, or evaluation of TMJ disorders. Documentation should specify the clinical finding of inadequate anterior guidance.

• Ensure documentation clearly states "insufficient anterior guidance" or a clinically equivalent term.
• Do not confuse this with other malocclusion codes unless insufficient anterior guidance is specifically noted.
• Consider co-reporting with codes for related conditions like temporomandibular joint disorders (M26.6x) or dental attrition (K03.0) if present and documented.
