Code Classification

  • Diseases of the digestive system
    (K00–K95)
    • Diseases of oral cavity and salivary glands
      (K00-K14)
      • Gingivitis and periodontal diseases
        (K05)

K05.30 is a billable diagnosis code used to specify a medical diagnosis of chronic periodontitis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like K05.30 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information

  • Chronic Periodontitis

    chronic inflammation and loss of periodontium that is associated with the amount of dental plaque or dental calculus present. chronic periodontitis occurs mostly in adults and was called adult periodontitis, but this disease can appear in young people.
  • Pericoronitis

    inflammation of the gingiva surrounding the crown of a tooth.
  • Aggressive Periodontitis

    inflammation and loss of periodontium that is characterized by rapid attachment loss and bone destruction in the presence of little local factors such as dental plaque and dental calculus. this highly destructive form of periodontitis often occurs in young people and was called early-onset periodontitis, but this disease also appears in old people.
  • Periapical Abscess

    acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis. (dorland, 27th ed)
  • Periapical Granuloma

    chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment.
  • Periapical Periodontitis

    inflammation of the periapical tissue. it includes general, unspecified, or acute nonsuppurative inflammation. chronic nonsuppurative inflammation is periapical granuloma. suppurative inflammation is periapical abscess.
  • Periodontitis

    inflammation and loss of connective tissues supporting or surrounding the teeth. this may involve any part of the periodontium. periodontitis is currently classified by disease progression (chronic periodontitis; aggressive periodontitis) instead of age of onset. (from 1999 international workshop for a classification of periodontal diseases and conditions, american academy of periodontology)
  • Chronic Periodontitis

    a chronic inflammatory process that affects the tissues that surround and support the teeth.
  • Acroosteolysis

    a condition that is characterized by degeneration of the distal phalanges.
  • Acute Periodontitis

    an acute inflammatory process that affects the tissues that surround and support the teeth.
  • Periodontitis

    an acute or chronic inflammatory process that affects the tissues that surround and support the teeth.
  • Chronic Pericoronitis

    long-term inflammation of the gingiva surrounding the crown of a tooth, usually of an incompletely erupted tooth.

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.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
