Necrosis of pulp

This code signifies the irreversible death of the dental pulp, the soft tissue within the tooth containing nerves and blood vessels. It typically results from severe inflammation (pulpitis) or trauma, leading to the complete cessation of pulpal vitality.

Apply this code when documentation explicitly states "pulpal necrosis," "necrotic pulp," or "non-vital pulp" confirmed by clinical and/or radiographic findings. This often occurs in cases of deep caries, extensive restorations, or dental trauma where the pulp has lost its blood supply and nerve function.

• Differentiate from reversible or irreversible pulpitis (K04.0-K04.09); necrosis indicates a non-vital tooth.
• Ensure documentation specifies necrosis and not just inflammation or degeneration.
• Consider sequencing with codes for the underlying cause, such as dental caries (K02.-) or dental trauma (S02.5-).
