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 calcification. These formations are an atypical hardening of the pulp tissue, often a response to chronic irritation or aging.

Apply this code when documentation indicates the presence of pulp calcifications, pulp stones, or denticles identified through radiographic examination or clinical observation. This is typically used when these formations are considered abnormal or symptomatic, contributing to pulpal pathology.

• Ensure documentation clearly specifies "abnormal" hard tissue formation; routine age-related calcification without pathology may not warrant this code.
• Differentiate from other pulpal conditions like pulpitis (686.0x) or pulpal necrosis (522.4) unless these conditions are also present and separately documented.
• This code describes the condition of the pulp, not the cause of the calcification.
