H00.026 Hordeolum internum left eye, unspecified eyelid

Name of the Condition

Hordeolum internum left eye, unspecified eyelid

Summary

Hordeolum internum left eye, unspecified eyelid is an acute bacterial infection of the meibomian glands within the left eyelid. It presents as a painful, localized swelling, often with pus accumulation, and is commonly referred to as an internal stye. The condition typically resolves spontaneously but may require medical intervention if symptoms persist or worsen.

Causes

The primary cause is bacterial infection, most commonly by Staphylococcus aureus, which invades the oil-producing glands of the eyelid. Blockage of these glands can predispose to infection and subsequent inflammation.

Risk Factors

• Poor eyelid hygiene
• Touching the eyes with unclean hands
• Use of expired or contaminated eye cosmetics
• Chronic blepharitis (eyelid inflammation)
• Underlying skin conditions such as rosacea or seborrheic dermatitis

Symptoms

• Tender, red swelling on the eyelid
• Pain or discomfort in the affected area
• Increased tear production
• Sensitivity to light
• A sensation of a foreign body in the eye

Diagnosis

Diagnosis is typically made through a physical examination by a healthcare professional, who evaluates the location and characteristics of the eyelid swelling. Additional tests are rarely necessary unless recurrent infections suggest an underlying condition.

Treatment Options

• Warm compresses applied several times daily to promote drainage
• Gentle eyelid massage to help express pus
• Antibiotic ointments or drops if infection is severe or persistent
• Oral antibiotics in cases of widespread or recurrent infection
• Avoidance of eye makeup and contact lenses until the condition resolves

Prognosis and Follow-Up

Most cases resolve within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen or fail to improve, as persistent infections could indicate an underlying issue. Recurrence is possible, especially in individuals with chronic eyelid inflammation.

Complications

• Spread of infection to surrounding tissues
• Formation of a chalazion (a painless, persistent lump) if the gland remains blocked
• Rarely, cellulitis or systemic infection in severe cases

Lifestyle & Prevention

• Maintain good eyelid hygiene by gently cleaning the eyelids with a warm, damp cloth
• Avoid touching or rubbing the eyes with unwashed hands
• Replace eye cosmetics regularly and avoid sharing them
• Manage underlying conditions like blepharitis or rosacea as directed by a healthcare provider

When to Seek Professional Help

Seek medical attention if the swelling worsens, spreads, or does not improve after a week of home care. Prompt evaluation is also recommended if vision changes, severe pain, or fever occurs.

Tips for Medical Coders

Use H00.026 for Hordeolum internum left eye, unspecified eyelid. Ensure documentation specifies the left eye and absence of eyelid (upper/lower) detail to support this code. Differentiate from external styes (hordeolum externum) and other eyelid infections for accurate coding.
