Other specified periodontal diseases

This code represents various periodontal conditions that do not fit into more specific categories of gingivitis or periodontitis. It encompasses a range of inflammatory and destructive diseases affecting the supporting structures of the teeth, excluding acute or chronic forms of gingivitis and periodontitis with specific etiologies. These conditions often involve unique presentations or underlying systemic factors.

Use this code for documented periodontal diseases that are clearly specified but do not have a more precise ICD-9-CM code. This includes conditions like necrotizing ulcerative periodontitis (NUP) or periodontitis associated with systemic diseases not otherwise classified. Documentation should clearly describe the specific "other" periodontal disease to support its use.

• Avoid using this code if a more specific ICD-9-CM code for gingivitis or periodontitis (e.g., 523.3, 523.4) is available and accurately reflects the diagnosis.
• Ensure the medical record explicitly states the "other specified" nature of the periodontal disease; vague documentation may lead to denial.
• Consider sequencing this code after any underlying systemic condition if the periodontal disease is a manifestation of that condition.
