ICD-9-CM Diagnosis Code 521 Diseases of hard tissues of teeth
ICD-9-CM Diagnosis Code 521.0 Dental caries
localized destruction of calcified tissue initiated on the tooth surface by decalcification of the enamel of the teeth, followed by enzymatic lysis of organic structures, leading to cavity formation that, if left untreated penetrates the enamel and dentin and may reach the pulp.
The decay of a tooth, in which it becomes softened, discolored, and/or porous.
ICD-9-CM Diagnosis Code 521.00Unspecified dental caries
localized destruction of calcified tissue initiated on the tooth surface by decalcification of the enamel of the teeth, followed by enzymatic lysis of organic structures, leading to cavity formation that, if left untreated penetrates the enamel and dentin and may reach the pulp.
The decay of a tooth, in which it becomes softened, discolored, and/or porous.
ICD-9-CM Diagnosis Code 521.01Dental caries limited to enamel
A chalky white area that appears on a tooth surface indicating the presence of decalcified enamel and the potential to advance to cavitation.
