H00.0 Hordeolum (externum) (internum) of eyelid

Name of the Condition

• Hordeolum (externum) (internum) of eyelid

Summary

A hordeolum is a localized infection or inflammation of the eyelid glands, presenting as a red, painful lump. It may occur externally (externum) or internally (internum) and is commonly known as a stye. The condition typically affects a single eyelid and resolves with minimal intervention.

Causes

Hordeolum is usually caused by a bacterial infection, most often Staphylococcus aureus, which infects the oil glands at the base of the eyelashes (externum) or within the eyelid (internum). Blockage of these glands can lead to inflammation and pus formation.

Risk Factors

• Poor eyelid hygiene
• Touching the eyes with unclean hands
• Use of contaminated eye makeup or contact lenses
• History of blepharitis (inflammation of the eyelids)
• Having seborrheic dermatitis or rosacea

Symptoms

• Red, swollen bump along the edge of the eyelid (externum) or within the eyelid (internum)
• Pain or tenderness in the affected area
• Increased tearing
• Crustiness around the eyelid
• Sensitivity to light

Diagnosis

A physical examination by an eye care professional is usually sufficient to diagnose a hordeolum. Additional tests are rarely needed unless recurrent styes suggest an underlying condition.

Treatment Options

• Warm compresses applied to the eyelid several times a day to promote drainage.
• Over-the-counter pain relievers for discomfort.
• Antibiotic ointments or drops if a secondary bacterial infection is present.
• Rarely, minor surgical intervention to drain the abscess.

Prognosis and Follow-Up

Most hordeola resolve on their own within a week with proper care. Follow-up may be recommended if symptoms persist or worsen, to rule out complications or underlying conditions.

Complications

• Spread of infection to surrounding tissues (cellulitis)
• Recurrence of the infection
• Rarely, preseptal cellulitis or systemic infection if left untreated.

Lifestyle & Prevention

• Maintain good eyelid hygiene by gently cleaning the eyelid margins with a clean cloth.
• Avoid touching or rubbing the eyes with unwashed hands.
• Replace eye makeup regularly and avoid sharing cosmetics.
• Manage underlying conditions like blepharitis or rosacea as advised by a healthcare provider.

When to Seek Professional Help

Seek medical attention if the hordeolum does not improve after a week, causes significant pain, affects vision, or is accompanied by fever or swelling around the eye.

Tips for Medical Coders

When coding for hordeolum, specify whether the condition is external (externum) or internal (internum) based on clinical documentation. Ensure the code aligns with the location and laterality of the eyelid affected. Documentation should clearly indicate the type and location to support accurate coding.
