I88.1 Chronic lymphadenitis, except mesenteric

Name of the Condition

• Chronic lymphadenitis, except mesenteric

Summary

Chronic lymphadenitis is the persistent inflammation of lymph nodes, excluding those in the mesenteric region. It involves prolonged swelling and may result from ongoing or recurrent infections, immune responses, or other underlying conditions.

Causes

The condition often stems from chronic infections (e.g., tuberculosis, fungal infections) or persistent immune stimulation. It can also arise from non-infectious causes like sarcoidosis or malignancies, though the exact etiology may remain unclear in some cases.

Risk Factors

• Prolonged or recurrent infections
• Weakened immune system
• Exposure to chronic infectious agents (e.g., mycobacteria)
• Underlying inflammatory or autoimmune disorders

Symptoms

• Persistent lymph node swelling
• Mild tenderness or discomfort
• Fatigue
• Low-grade fever (in some cases)

Diagnosis

Physical examination to assess lymph node characteristics. Imaging (e.g., ultrasound, CT) to evaluate size and structure. Biopsy or fine-needle aspiration to identify underlying causes, such as infection or malignancy.

Treatment Options

• Antibiotics or antifungals for infectious causes
• Anti-inflammatory medications to reduce swelling
• Treatment of underlying conditions (e.g., sarcoidosis)
• Surgical removal of affected nodes in select cases

Prognosis and Follow-Up

Prognosis depends on the underlying cause. With appropriate treatment, swelling may resolve, but chronic cases may require ongoing monitoring. Follow-up ensures resolution and addresses potential complications.

Complications

• Persistent lymph node enlargement
• Abscess formation
• Spread of infection
• Tissue damage from chronic inflammation

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk
• Manage chronic conditions (e.g., diabetes) to support immune function
• Seek prompt treatment for infections to prevent progression

When to Seek Professional Help

Consult a healthcare provider if lymph node swelling persists beyond a few weeks, worsens, or is accompanied by fever, weight loss, or other concerning symptoms.

Tips for Medical Coders

Document the location of affected lymph nodes (excluding mesenteric) and any identified underlying causes. Ensure clinical notes support the chronic nature of the condition for accurate coding.
