J01.0 Acute maxillary sinusitis

Name of the Condition

• Acute maxillary sinusitis

Summary

Acute maxillary sinusitis is an inflammation of the maxillary sinuses, typically resulting from an infection. It causes symptoms such as facial pain, nasal congestion, and purulent discharge, often following a viral upper respiratory infection.

Causes

Bacterial or viral infections are the primary causes. The condition often develops after a cold or other upper respiratory infection. Allergies and environmental irritants may also contribute to inflammation.

Risk Factors

• Recent upper respiratory infections.
• Allergies, particularly allergic rhinitis.
• Smoking or exposure to secondhand smoke.
• A history of sinusitis or nasal polyps.

Symptoms

• Facial pain or pressure, especially around the cheeks.
• Nasal congestion and thick, discolored nasal discharge.
• Reduced sense of smell.
• Headache, fever, and fatigue.

Diagnosis

Clinical evaluation by a healthcare provider is standard. Nasal endoscopy may be used for detailed inspection. Imaging tests like CT scans are reserved for chronic or complicated cases. Cultures of nasal discharge can identify bacterial involvement.

Treatment Options

• Antibiotics for bacterial infections.
• Decongestants and antihistamines to relieve symptoms.
• Nasal corticosteroids to reduce inflammation.
• Saline nasal irrigation to clear mucus.
• In rare cases, surgical intervention may be necessary.

Prognosis and Follow-Up

Most cases resolve with appropriate treatment within 7–10 days. Follow-up may be needed if symptoms persist or worsen. Chronic or recurrent cases require further evaluation.

Complications

• Spread of infection to nearby structures, such as the eyes or brain.
• Development of chronic sinusitis.
• Abscess formation.

Lifestyle & Prevention

• Avoid smoking and secondhand smoke.
• Use a humidifier to maintain moisture.
• Practice good hand hygiene to reduce infection risk.
• Manage allergies effectively.

When to Seek Professional Help

Seek care if symptoms worsen after initial improvement, last longer than 10 days, or include severe facial pain, high fever, or vision changes.

Tips for Medical Coders

Document the presence of acute symptoms, such as facial pain, nasal discharge, and fever, to support the diagnosis. Include details about imaging or cultures if performed. Ensure documentation aligns with the clinical criteria for acute maxillary sinusitis.
