Periodontosis

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

What This Code Means

A degenerative gum disease characterized by progressive loss of the tissues and bone supporting the teeth, typically without significant inflammation.

Coding Tips

  • •Periodontosis is distinct from periodontitis; it involves tissue degeneration rather than inflammatory destruction
  • •This is a rare diagnosis; ensure clinical documentation specifically identifies periodontosis rather than chronic or aggressive periodontitis
