Horizontal alveolar bone loss

This code represents the pathological loss of alveolar bone support around teeth, characterized by a reduction in bone height that is relatively uniform across the tooth root surface. It is a common manifestation of chronic periodontitis, leading to decreased stability of the dentition.

Use this code when dental radiographs and clinical examination confirm a generalized or localized reduction in the horizontal dimension of the alveolar bone. Documentation should specify "horizontal bone loss" or describe bone loss that is not primarily vertical or angular.

• Differentiate from vertical or angular bone loss, which may indicate a different disease progression or localized defect.
• This code is typically used in conjunction with codes for periodontitis (e.g., K05.30, K05.31) to specify the type of bone involvement.
• Ensure the documentation clearly states the pattern of bone loss as "horizontal" to support this specific code.
