H00.029 Hordeolum internum unspecified eye, unspecified eyelid

Name of the Condition

Hordeolum internum unspecified eye, unspecified eyelid

Summary

Hordeolum internum unspecified eye, unspecified eyelid is an acute bacterial infection of the meibomian glands within the 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 release 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, fail to improve, or recur frequently. Recurrent infections may warrant evaluation for underlying conditions like blepharitis or diabetes.

Complications

• Spread of infection to surrounding tissues
• Formation of a chalazion (chronic 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 daily
• 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
• Use clean towels and avoid sharing eye care products

When to Seek Professional Help

Seek medical attention if the swelling worsens, spreads, causes vision changes, or is accompanied by fever. Persistent symptoms after home care or recurrent infections also warrant evaluation.

Tips for Medical Coders

This code (H00.029) is used when the location of the hordeolum internum is unspecified for both the eye and eyelid. Documentation should specify whether the condition affects the upper or lower eyelid and which eye (right, left, or bilateral) to ensure accurate coding. If laterality or eyelid location becomes known, the code should be updated to reflect the specific details.
