K08.423 Partial loss of teeth due to periodontal diseases, class III

Name of the Condition

• Partial Loss of Teeth Due to Periodontal Diseases, Class III (ICD-10-CM Code: K08.423)

Summary

Partial loss of teeth due to periodontal diseases, class III, describes a severe stage of tooth loss resulting from advanced gum disease. This condition involves significant destruction of the periodontal tissues and bone, leading to the loss of multiple teeth. The classification indicates the extent of tooth loss and the underlying periodontal pathology.

Causes

Periodontal disease, driven by bacterial plaque and tartar accumulation, is the primary cause. Untreated periodontitis progresses to destroy gum tissue, ligaments, and bone, resulting in tooth loosening and loss. Contributing factors include poor oral hygiene, genetic susceptibility, and systemic conditions like diabetes that impair immune response.

Risk Factors

• Smoking or tobacco use
• Advanced age
• Family history of periodontal disease
• Poor oral hygiene practices
• Systemic diseases (e.g., diabetes, cardiovascular disease)
• Hormonal changes (e.g., pregnancy, menopause)
• Certain medications that reduce saliva flow

Symptoms

• Severe gum recession
• Multiple loose or missing teeth
• Persistent bad breath
• Pain or difficulty chewing
• Visible bone loss on X-rays
• Gum abscesses or pus

Diagnosis

Diagnosis requires a comprehensive dental examination, including probing for deep gum pockets and assessing tooth mobility. Dental X-rays are used to evaluate extensive bone loss around teeth. Clinical findings of advanced periodontal disease and significant tooth loss confirm the condition.

Treatment Options

• Professional deep cleaning (scaling and root planing)
• Antibiotics to control infection
• Periodontal surgery (e.g., flap surgery, bone grafts)
• Tooth replacement options (e.g., bridges, implants)
• Ongoing maintenance to prevent further loss

Prognosis and Follow-Up

Prognosis depends on the extent of bone loss and response to treatment. Regular dental follow-ups are essential to monitor gum health and prevent recurrence. Early intervention can slow progression, but severe cases may require long-term management.

Complications

• Further tooth loss
• Difficulty chewing or speaking
• Jawbone deterioration
• Increased risk of systemic infections
• Emotional or psychological impact due to appearance

Lifestyle & Prevention

• Maintain rigorous oral hygiene (brushing, flossing)
• Quit smoking or avoid tobacco use
• Manage systemic conditions (e.g., diabetes)
• Regular dental check-ups and cleanings
• Balanced diet to support oral health

When to Seek Professional Help

Seek dental care if you experience persistent gum bleeding, loose teeth, or unexplained tooth loss. Early evaluation can prevent progression to severe stages.

Tips for Medical Coders

Document the extent of tooth loss and periodontal disease severity to support the K08.423 code. Include clinical notes on bone loss, pocket depth, and treatment history. Ensure the code aligns with the specific class III classification for accurate reporting.
