Billable

Chronic periodontitis, localized, severe

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

What This Code Means

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

Coding Tips

  • •The '313' suffix indicates localized disease with severe manifestations; document specific tooth sites and extent of bone loss or pocket depth
  • •Severe periodontitis may require more aggressive treatment; ensure severity is clinically justified in the record
