K08.422 Partial loss of teeth due to periodontal diseases, class II

Name of the Condition

• Partial Loss of Teeth Due to Periodontal Diseases, Class II (ICD-10-CM Code: K08.422)

Summary

Partial loss of teeth due to periodontal diseases, class II, describes a moderate stage of tooth loss resulting from gum disease. This condition involves the progressive destruction of the periodontal tissues and supporting bone, leading to the loosening and loss of multiple teeth. The classification indicates a specific severity level within the broader category of periodontal-related tooth loss.

Causes

Periodontal disease, driven by bacterial plaque and tartar accumulation, is the primary cause. Untreated gingivitis can advance to periodontitis, where inflammation and infection damage the gums, ligaments, and jawbone. Contributing factors include poor oral hygiene, inadequate dental care, and systemic conditions that impair immune response or tissue healing.

Risk Factors

• Smoking or tobacco use
• Chronic systemic diseases (e.g., diabetes)
• Genetic predisposition to periodontal disease
• Poor oral hygiene practices
• Advanced age
• Certain medications affecting gum health

Symptoms

• Noticeable gaps or missing teeth
• Persistent gum inflammation or bleeding
• Receding gums exposing tooth roots
• Difficulty chewing or speaking
• Loose or shifting teeth
• Bad breath (halitosis)

Diagnosis

Diagnosis requires a comprehensive dental evaluation, including periodontal probing to measure pocket depths, assessment of tooth mobility, and radiographic imaging (X-rays) to evaluate bone loss. Clinical findings are correlated with the patient’s history of periodontal disease and treatment response to classify the severity as class II.

Treatment Options

• Professional dental cleaning and scaling to remove plaque/tartar
• Root planing to smooth tooth roots and reduce inflammation
• Antibiotic therapy (topical or systemic) to control infection
• Periodontal surgery (e.g., flap procedures) for moderate bone loss
• Tooth replacement options (bridges, implants) after stabilization
• Ongoing maintenance to prevent further progression

Prognosis and Follow-Up

With appropriate treatment, progression can be slowed, but lost teeth may require prosthetic replacement. Regular dental visits (every 3–6 months) are essential to monitor gum health and prevent recurrence. Prognosis depends on adherence to oral hygiene and management of underlying risk factors.

Complications

• Further tooth loss if periodontal disease progresses
• Bone loss in adjacent areas
• Increased risk of systemic infections (e.g., cardiovascular issues)
• Nutritional deficiencies due to chewing difficulties
• Psychological impact from altered appearance or function

Lifestyle & Prevention

• Maintain rigorous oral hygiene (brushing, flossing, antimicrobial rinses)
• Quit smoking or using tobacco products
• Manage systemic conditions (e.g., diabetes) to reduce gum disease risk
• Use interdental cleaners or water flossers as recommended
• Attend regular dental check-ups for early intervention

When to Seek Professional Help

Seek prompt dental care if experiencing persistent gum bleeding, loose teeth, or worsening pain. Early intervention can prevent irreversible bone loss and tooth loss. Emergency care may be needed for acute infections or severe pain.

Tips for Medical Coders

Document the specific classification (class II) and confirm the link to periodontal disease in the medical record. Ensure the code K08.422 is used only when the loss is partial and directly attributable to periodontal disease, with supporting clinical details. Avoid using this code for tooth loss from other causes (e.g., trauma, decay) without clear documentation.
