Billable

Chronic periodontitis, localized, slight

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This code describes a long-term gum disease affecting specific areas of the mouth where the gums and bone supporting the teeth are mildly damaged. The condition is localized, meaning it affects only certain teeth rather than the entire mouth.

Coding Tips

  • •Verify the periodontitis is documented as 'chronic' and 'localized' (not generalized) before assigning this code, as these distinctions affect code selection
  • •Ensure the severity is documented as 'slight' in the clinical notes; if severity is moderate or severe, different codes (K05.312 or K05.313) would apply instead
