K05.312

Billable

Chronic periodontitis, localized, moderate

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

What This Code Means

A moderate form of long-term gum disease affecting one or a few specific areas of the mouth, with moderate tissue damage.

Coding Tips

  • •The '312' suffix indicates localized (limited to specific tooth areas) and moderate severity; ensure documentation specifies which teeth or areas are affected
  • •Distinguish between localized (K05.31x) and generalized (K05.32x) based on whether disease affects isolated sites or multiple areas throughout the mouth
