Code Description

ICD-10 K08.124 is a billable code used to indicate a diagnosis of complete loss of teeth due to periodontal diseases, class iv.

Key Diagnostic Point:

K08.124 refers to complete loss of teeth due to periodontal diseases, class IV, which is characterized by severe periodontal disease leading to the total loss of teeth. Periodontal diseases affect the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone. The disease progression typically begins with gingivitis, which can advance to periodontitis if not treated. In class IV, the destruction of the periodontal tissues is extensive, resulting in tooth mobility and eventual loss. Clinically, patients may present with symptoms such as gum inflammation, bleeding, and significant tooth loss. Diagnostic considerations include clinical examinations, radiographic evaluations, and periodontal probing to assess the extent of tissue loss and bone resorption. Effective management often requires a multidisciplinary approach, including dental hygiene, periodontal therapy, and possibly surgical interventions to restore oral health and function.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Diagnostic complexity: Requires thorough periodontal assessment and imaging.
  • Treatment complexity: Involves multiple treatment modalities and potential referrals.
  • Documentation requirements: Detailed records of periodontal assessments and treatment plans are necessary.
  • Coding specificity: Specific to complete tooth loss due to periodontal disease, necessitating precise coding.

Audit Risk Factors

  • Common coding errors: Misclassification of the severity of periodontal disease.
  • Documentation gaps: Incomplete records of periodontal assessments and treatment history.
  • Billing challenges: Potential denials due to insufficient documentation supporting the diagnosis.

ICD-10 Improvements

The clinical significance of K08.124 extends beyond individual patient health, as complete tooth loss can lead to functional impairments, nutritional deficiencies, and psychosocial issues. Population health impacts include increased healthcare utilization for dental and medical services related to periodontal disease. Quality measures may focus on the prevention and management of periodontal disease to reduce the incidence of tooth loss. Epidemiologically, the prevalence of periodontal disease and its association with systemic conditions underscores the importance of early intervention and comprehensive dental care.

Frequently Asked Questions

What specific conditions are covered by K08.124?

K08.124 covers complete loss of teeth specifically due to advanced periodontal diseases, including chronic periodontitis and aggressive periodontitis, where the loss of teeth is irreversible and directly linked to the periodontal condition.

When should K08.124 be used instead of related codes?

K08.124 should be used when there is complete loss of teeth attributed to periodontal disease, distinguishing it from codes for partial tooth loss or loss due to other causes such as trauma or caries.

What documentation supports K08.124?

Documentation should include comprehensive periodontal evaluations, clinical notes detailing the extent of periodontal disease, radiographic evidence of bone loss, and treatment plans that outline the management of periodontal disease leading to tooth loss.
