ICD-10 Code K05.32 – Chronic periodontitis, generalized (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K05.32 – Chronic periodontitis, generalized
What it is
K05.32 identifies generalized chronic periodontitis, a long-standing inflammatory disease affecting the supporting tissues of many teeth. Use it when the record clearly documents generalized periodontal breakdown rather than a localized site.
Clinical signs
Typical findings include gingival inflammation, periodontal pocketing, attachment loss, and bone loss affecting multiple teeth. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic periodontitis and specifies that it is generalized. It is appropriate for dental or medical records that describe widespread periodontal involvement across the mouth. Check documentation if the note only says periodontitis without chronicity or distribution.
Do not use for
Do not use K05.32 for localized periodontitis or for gingivitis without periodontal attachment loss. If the chart does not confirm generalized disease, choose the more specific documented diagnosis or check documentation.
Coding tip
Confirm both chronicity and generalized distribution in the provider note before assigning K05.32.
