ICD-10:K05.2
Short Description:Aggressive periodontitis
Long Description:Aggressive periodontitis
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the digestive system (K00–K93)
    • Diseases of oral cavity and salivary glands (K00-K14)
      • Gingivitis and periodontal diseases (K05)

K05.2 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of aggressive periodontitis. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Clinical Information

Specific Coding for Aggressive periodontitis

Non-specific codes like K05.2 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 aggressive periodontitis:

  • BILLABLE CODE - Use K05.20 for Aggressive periodontitis, unspecified
  • NON-BILLABLE CODE - K05.21 for Aggressive periodontitis, localized
  • BILLABLE CODE - Use K05.211 for Aggressive periodontitis, localized, slight
  • BILLABLE CODE - Use K05.212 for Aggressive periodontitis, localized, moderate
  • BILLABLE CODE - Use K05.213 for Aggressive periodontitis, localized, severe
  • BILLABLE CODE - Use K05.219 for Aggressive periodontitis, localized, unspecified severity
  • NON-BILLABLE CODE - K05.22 for Aggressive periodontitis, generalized
  • BILLABLE CODE - Use K05.221 for Aggressive periodontitis, generalized, slight
  • BILLABLE CODE - Use K05.222 for Aggressive periodontitis, generalized, moderate
  • BILLABLE CODE - Use K05.223 for Aggressive periodontitis, generalized, severe
  • BILLABLE CODE - Use K05.229 for Aggressive periodontitis, generalized, unspecified severity

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Patient Education


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.
