Specific Coding for Gingivitis and periodontal diseases

Non-specific codes like K05 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for gingivitis and periodontal diseases:

  • NON-BILLABLE CODE - K05.0 for Acute gingivitis
  • BILLABLE CODE - Use K05.00 for Acute gingivitis, plaque induced
  • BILLABLE CODE - Use K05.01 for Acute gingivitis, non-plaque induced
  • NON-BILLABLE CODE - K05.1 for Chronic gingivitis
  • BILLABLE CODE - Use K05.10 for Chronic gingivitis, plaque induced
  • BILLABLE CODE - Use K05.11 for Chronic gingivitis, non-plaque induced
  • NON-BILLABLE CODE - K05.2 for Aggressive periodontitis
  • BILLABLE CODE - Use K05.20 for Aggressive periodontitis, unspecified
  • NON-BILLABLE CODE - K05.21 for Aggressive periodontitis, localized
  • NON-BILLABLE CODE - K05.22 for Aggressive periodontitis, generalized
  • NON-BILLABLE CODE - K05.3 for Chronic periodontitis
  • BILLABLE CODE - Use K05.30 for Chronic periodontitis, unspecified
  • NON-BILLABLE CODE - K05.31 for Chronic periodontitis, localized
  • NON-BILLABLE CODE - K05.32 for Chronic periodontitis, generalized

Information for Patients


Gum Disease

If you have gum disease, you're not alone. Many U.S. adults currently have some form of the disease. It ranges from simple gum inflammation, called gingivitis, to serious damage to the tissue and bone supporting the teeth. In the worst cases, you can lose teeth.

In gingivitis, the gums become red and swollen. They can bleed easily. Gingivitis is a mild form of gum disease. You can usually reverse it with daily brushing and flossing and regular cleanings by a dentist or dental hygienist. Untreated gingivitis can lead to periodontitis. If you have periodontitis, the gums pull away from the teeth and form pockets that become infected. If not treated, the bones, gums and connective tissue that support the teeth are destroyed.
