Endodontic overfill

This code signifies the presence of excess root canal filling material that extends beyond the apex of the tooth root into the periapical tissues. This overextension can occur during endodontic treatment and may lead to inflammation, pain, or infection.

Assign this code when documentation explicitly states "endodontic overfill," "root canal overextension," or describes radiographic evidence of obturation material beyond the confines of the root canal system. This condition is typically identified post-procedure or during follow-up examinations.

• Ensure documentation specifies overfill and not merely adequate fill or underfill.
• Do not confuse with codes for failed root canal treatment unless overfill is the documented cause of failure.
• Consider sequencing this code after a code for the underlying dental condition that necessitated the endodontic treatment, if applicable.
