H00.024 Hordeolum internum left upper eyelid

Name of the Condition

Hordeolum internum left upper eyelid

Summary

Hordeolum internum left upper eyelid is an acute bacterial infection of the meibomian glands within the left upper 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
• Topical antibiotic ointments or drops if infection is present
• Oral antibiotics for severe or persistent cases
• Avoidance of eye makeup and contact lenses during active infection

Prognosis and Follow-Up

Most cases resolve within 1–2 weeks with appropriate care. Follow-up may be recommended if symptoms worsen or fail to improve, as recurrent infections could indicate an underlying condition. Complications are rare but may include spread of infection or eyelid scarring.

Complications

• Spread of infection to surrounding tissues
• Formation of a chalazion (chronic inflammation)
• Eyelid scarring or distortion
• Rarely, cellulitis or systemic infection in immunocompromised individuals

Lifestyle & Prevention

• Maintain good eyelid hygiene by gently cleaning the eyelids with a warm washcloth
• Avoid touching 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
• Use clean towels and avoid sharing personal eye care items

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond two weeks, or if there is significant pain, vision changes, or signs of spreading infection (e.g., redness extending beyond the eyelid). Immediate care is needed if fever or systemic symptoms develop.

Tips for Medical Coders

Document the specific location (left upper eyelid) and laterality (left) to ensure accurate coding. Verify that the diagnosis aligns with clinical findings, as Hordeolum internum is distinguished from external styes (hordeolum externum) by its deeper glandular involvement. Include details about infection severity or treatment response if relevant to support medical necessity.
