Fracture of tooth (traumatic), init for clos fx

This code signifies a traumatic break or crack in a tooth that does not involve a break in the overlying skin or mucous membrane. It specifically indicates the initial treatment or evaluation for such an injury. The fracture can range from a minor chip to a complete crown or root fracture.

Apply this code when documentation clearly states a tooth fracture resulting from trauma, such as a fall, sports injury, or accident, and the fracture is closed (no open wound communicating with the fracture site). This code is appropriate for the first encounter where the patient presents for diagnosis and initial management of the injury. Supporting documentation includes dental examination notes, imaging reports (e.g., X-rays), and a clear history of trauma.

• Ensure the documentation specifies "traumatic" etiology; otherwise, consider codes for non-traumatic tooth fractures (e.g., K03.8).
• Verify the encounter is indeed the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Distinguish from codes for luxation or avulsion, which involve displacement or complete removal of the tooth, respectively, rather than a fracture.
