Code Description

ICD-10 K08.424 is a billable code used to indicate a diagnosis of partial loss of teeth due to periodontal diseases, class iv.

Key Diagnostic Point:

K08.424 refers to partial loss of teeth due to periodontal diseases, classified as class IV. This condition typically arises from chronic inflammatory processes affecting the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone. Clinically, patients may present with gum recession, mobility of teeth, and eventual tooth loss. The disease progression often begins with gingivitis, leading to periodontitis if untreated. The anatomy involved includes the periodontal tissues, which are critical for tooth stability and overall oral health. Diagnostic considerations include clinical examinations, radiographic assessments, and periodontal probing to evaluate the extent of attachment loss and bone loss. Effective management requires a multidisciplinary approach, including dental hygiene, periodontal therapy, and possibly surgical interventions to restore periodontal health and prevent further tooth loss.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Diagnostic complexity: Requires thorough clinical evaluation and understanding of periodontal disease stages.
  • Treatment complexity: Involves various treatment modalities from non-surgical to surgical interventions.
  • Documentation requirements: Detailed documentation of clinical findings, treatment plans, and patient compliance is essential.
  • Coding specificity: Requires precise coding to differentiate between various periodontal conditions.

Audit Risk Factors

  • Common coding errors: Misclassification of periodontal disease severity or failure to document the extent of tooth loss.
  • Documentation gaps: Incomplete records of periodontal assessments or treatment history.
  • Billing challenges: Potential denials if documentation does not support the severity of the condition or the necessity of procedures performed.

Enhanced Specificity

ICD-10 Improvements

The clinical significance of K08.424 lies in its association with systemic health issues, as periodontal disease has been linked to conditions such as cardiovascular disease and diabetes. The population health impact is substantial, given that periodontal disease affects a significant portion of adults, leading to increased healthcare utilization for dental and related medical services. Quality measures related to oral health are increasingly recognized in overall healthcare assessments, emphasizing the importance of managing periodontal diseases effectively.

ICD-9 vs ICD-10

The clinical significance of K08.424 lies in its association with systemic health issues, as periodontal disease has been linked to conditions such as cardiovascular disease and diabetes. The population health impact is substantial, given that periodontal disease affects a significant portion of adults, leading to increased healthcare utilization for dental and related medical services. Quality measures related to oral health are increasingly recognized in overall healthcare assessments, emphasizing the importance of managing periodontal diseases effectively.

Reimbursement & Billing Impact

Reimbursement considerations include the necessity of procedures performed, which should be supported by clinical evidence. Common denials may arise from insufficient documentation of the severity of periodontal disease or lack of evidence for the need for surgical interventions. Best practices include ensuring that all treatment notes are comprehensive and that the rationale for procedures is clearly articulated in the patient's record.

Frequently Asked Questions

What specific conditions are covered by K08.424?

K08.424 specifically covers partial loss of teeth attributed to periodontal diseases classified as class IV, which includes significant attachment loss and mobility of teeth due to advanced periodontal disease.

When should K08.424 be used instead of related codes?

K08.424 should be used when there is documented evidence of partial tooth loss specifically due to periodontal disease, particularly when the disease has progressed to class IV, indicating severe attachment loss.

What documentation supports K08.424?

Documentation for K08.424 should include clinical findings from periodontal examinations, radiographic evidence of bone loss, treatment plans, and any relevant patient history that supports the diagnosis of periodontal disease leading to tooth loss.
