Clinical InformationClinical

  • Alveolar Bone Loss

    resorption or wasting of the tooth-supporting bone (alveolar process) in the maxilla or mandible.

  • Gingival Recession

    exposure of the root surface when the edge of the gum (gingiva) moves apically away from the crown of the tooth. this is common with advancing age, vigorous tooth brushing, diseases, or tissue loss of the gingiva, the periodontal ligament and the supporting bone (alveolar process).

  • Benign Mucous Membrane Pemphigoid

    a chronic autoimmune disorder characterized by the development of blisters and ulcers in mucous membranes. it affects most often the gums, eyelids and genital mucosa sites.

Patient EducationClinical

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.

Questions About K06.8Overview

Is K06.8 (Other disorders of gingiva and edentulous alveolar ridge) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified disorders of gingiva and edentulous alveolar ridge on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does K06.8 group to?

When other specified disorders of gingiva and edentulous alveolar ridge is the principal diagnosis on an inpatient stay, it groups to MS-DRG 157, 158, 159, with relative weights from 0.7085 to 1.7168 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of K06.8?

Under the General Equivalence Mappings, other specified disorders of gingiva and edentulous alveolar ridge converts to ICD-9-CM 523.8 (periodontal disease NEC). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
