Abnormal hard tissue formation in pulp

This code signifies the pathological development of calcified structures within the dental pulp, such as pulp stones (denticles) or diffuse calcifications. These formations can occur in response to trauma, caries, restorative procedures, or aging, potentially leading to pulpitis or nerve impingement.

Use this code when documentation explicitly states the presence of abnormal hard tissue within the pulp chamber or root canal system. This includes findings like pulp stones identified on radiographs or during endodontic treatment, or histological confirmation of pulp calcification.

• Ensure documentation specifies "abnormal" or "pathological" hard tissue formation to differentiate from normal dentin.
• Do not use for normal physiological dentin formation.
• Consider sequencing with codes for associated conditions like pulpitis if present.
