Accretions on teeth

This code represents the presence of hard deposits, such as calculus (tartar) or plaque, on the surfaces of teeth. These accretions are typically mineralized bacterial biofilms that adhere to the enamel and root surfaces, contributing to periodontal disease and dental caries.

Use this code when documentation indicates the presence of calculus, plaque, or other non-carious deposits on the teeth. This is commonly identified during routine dental examinations, prophylaxis, or when evaluating for periodontal conditions. Supporting documentation would include findings from a dental hygienist or dentist noting the presence and location of these accretions.

• Do not use this code for intrinsic or extrinsic tooth stains without accompanying calculus or plaque.
• Consider additional codes for associated conditions such as gingivitis (e.g., 523.0) or periodontitis (e.g., 523.3) if documented.
• This code is often used in conjunction with dental prophylaxis or scaling and root planing procedures.
