K08.429

What This Code Means

This code describes the loss of some teeth caused by gum disease (periodontal disease), where the specific classification or pattern of tooth loss is not specified. The patient has retained some teeth but has lost others due to the progression of their gum disease.

Coding Tips

• •Verify documentation specifies periodontal disease as the cause of tooth loss; if the cause is unclear or due to other factors (trauma, decay, extraction), use a different K08 code
• •The 'unspecified class' designation means the dentist did not classify the pattern of tooth loss (Kennedy class I-IV); if documentation includes a specific class, use K08.421-K08.428 instead
