521.5
ICD-9-CMThis code signifies an excessive formation of cementum, the calcified tissue covering the tooth root. This overgrowth can occur on single or multiple teeth, often appearing as a bulbous enlargement of the root surface. It is typically a benign condition, though it can complicate tooth extraction.
Apply this code when documentation explicitly states a diagnosis of hypercementosis. This diagnosis is often made radiographically, where the root appears enlarged and distinct from the surrounding bone. It may also be identified during surgical procedures or tooth extraction.
