Abrasion of teeth

This code describes the loss of tooth structure due to mechanical wear from foreign objects or substances, excluding tooth-to-tooth contact (attrition) or chemical erosion. It often presents as V-shaped notches at the gumline or generalized wear on tooth surfaces.

Use this code when documentation specifies tooth abrasion caused by factors like aggressive toothbrushing, abrasive dentifrices, or habits such as holding objects between teeth. Supporting documentation should clearly distinguish abrasion from other forms of tooth wear like attrition or erosion.

• Differentiate from K03.0 (Excessive attrition of teeth) which is wear from tooth-to-tooth contact.
• Distinguish from K03.2 (Erosion of teeth) which is chemical loss of tooth structure.
• Ensure the documentation specifies the mechanical nature of the wear to justify this code.
