B30.2 Viral pharyngoconjunctivitis

Name of the Condition

• Viral pharyngoconjunctivitis

Summary

Viral pharyngoconjunctivitis is an inflammation of the pharynx (throat) and conjunctiva (the thin membrane covering the white part of the eye and inner eyelid) caused by viral infections. It is highly contagious and often presents with symptoms affecting both the eyes and upper respiratory tract.

Causes

Viral pharyngoconjunctivitis is typically caused by adenoviruses, which are common respiratory viruses. Transmission occurs through direct contact with infected eye secretions, respiratory droplets, or contaminated surfaces.

Risk Factors

• Close contact with infected individuals.
• Crowded environments like schools or daycare centers.
• Poor hand hygiene practices.
• Recent upper respiratory infections or colds.
• Use of contact lenses with inadequate hygiene.

Symptoms

• Redness in one or both eyes.
• Watery or clear discharge from the eyes.
• Itching or burning sensation in the eyes.
• Gritty feeling in the eyes.
• Swollen eyelids.
• Sore throat or pharyngeal irritation.
• Fever or general malaise.
• Sensitivity to light.

Diagnosis

Diagnosis is primarily based on clinical examination and patient history. A healthcare provider may assess symptoms and rule out bacterial or allergic causes. In some cases, swabs of eye discharge or throat secretions may be taken for laboratory testing to confirm the viral etiology.

Treatment Options

• Symptomatic relief with lubricating eye drops (artificial tears) to alleviate dryness and discomfort.
• Over-the-counter pain relievers or fever reducers for throat pain or fever.
• Rest and hydration to support recovery.
• Avoiding contact lenses until symptoms resolve.
• Good hand hygiene to prevent spread.

Prognosis and Follow-Up

Viral pharyngoconjunctivitis typically resolves on its own within 1–2 weeks. Follow-up may be recommended if symptoms worsen or persist beyond this timeframe, or if complications such as corneal involvement occur.

Complications

• Corneal inflammation (keratitis) in severe cases.
• Secondary bacterial infection.
• Prolonged eye irritation or dryness.
• Spread to other individuals in close contact.

Lifestyle & Prevention

• Practice frequent handwashing with soap and water.
• Avoid touching the eyes or face with unwashed hands.
• Disinfect surfaces and personal items (e.g., towels, pillows) regularly.
• Stay home from work or school if symptomatic to prevent transmission.
• Avoid sharing personal items like towels or makeup.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond two weeks, or include severe eye pain, vision changes, high fever, or difficulty breathing.

Tips for Medical Coders

When coding for viral pharyngoconjunctivitis, use ICD-10-CM code B30.2. Ensure documentation supports the presence of both pharyngeal and conjunctival inflammation, as well as viral etiology, to justify the code assignment.
