Code Description

ICD-10 K08.429 is a billable code used to indicate a diagnosis of partial loss of teeth due to periodontal diseases, unspecified class.

Key Diagnostic Point:

K08.429 refers to partial loss of teeth due to periodontal diseases, unspecified class. Periodontal diseases encompass a range of inflammatory conditions affecting the supporting structures of the teeth, primarily the gums and bone. Clinically, patients may present with symptoms such as gum inflammation, bleeding, and eventual tooth mobility or loss. The anatomy involved includes the gingiva, periodontal ligament, and alveolar bone. Disease progression typically begins with gingivitis, which, if untreated, can advance to periodontitis, leading to the destruction of the supporting structures and resulting in tooth loss. Diagnostic considerations include clinical examinations, radiographic assessments, and periodontal probing to evaluate the extent of attachment loss and pocket depth. The unspecified class indicates that the specific type of periodontal disease has not been determined, necessitating further evaluation to guide treatment and management effectively.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Diagnostic complexity: Requires thorough clinical evaluation and possibly imaging.
  • Treatment complexity: May involve non-surgical and surgical interventions depending on severity.
  • Documentation requirements: Detailed records of clinical findings and treatment plans are essential.
  • Coding specificity: Limited specificity due to the unspecified nature of the code.

Audit Risk Factors

  • Common coding errors: Misuse of unspecified codes when more specific codes are available.
  • Documentation gaps: Incomplete records of periodontal assessments may lead to coding inaccuracies.
  • Billing challenges: Difficulty in justifying claims for treatment without adequate documentation.

ICD-10 Improvements

The clinical significance of K08.429 lies in its association with oral health and overall systemic health, as periodontal diseases have been linked to conditions such as diabetes and cardiovascular disease. The population health impact is notable, as periodontal disease is prevalent and can lead to significant healthcare utilization patterns, including increased dental visits and potential hospitalizations for related systemic conditions. Quality measures related to periodontal health are essential for improving patient outcomes and reducing healthcare costs.

Frequently Asked Questions

What specific conditions are covered by K08.429?

K08.429 covers partial tooth loss resulting from various periodontal diseases, including chronic periodontitis and aggressive periodontitis, where the specific type of disease is not documented.

When should K08.429 be used instead of related codes?

K08.429 should be used when there is partial tooth loss due to periodontal disease but the specific type is not identified. If a more specific diagnosis is available, related codes should be utilized.

What documentation supports K08.429?

Documentation should include clinical findings from periodontal examinations, radiographic evidence of bone loss, treatment plans, and progress notes that reflect the patient's periodontal status.
