Perforation of root canal space due to endodontic treatment

This code signifies an iatrogenic opening or communication created in the root canal system, specifically through the root surface, as a direct consequence of endodontic therapy. This complication can occur during various stages of root canal treatment, such as access preparation, canal instrumentation, or post-space preparation.

Use this code when documentation clearly indicates a perforation of the root canal space that occurred during or as a direct result of endodontic treatment. This includes perforations caused by instruments, burs, or posts. Supporting documentation should specify the iatrogenic nature of the perforation.

• Differentiate from other types of root perforations, such as those due to caries or resorption, which would be coded differently.
• Ensure the documentation explicitly links the perforation to the endodontic treatment.
• Consider sequencing this code after the primary reason for the endodontic treatment if the perforation is a complication of an ongoing procedure.
