Understanding Hordeolum: Synonyms and Related Terms

Hordeolum is the official ICD-11 classification for a common eyelid condition. It is widely recognised by its patient-friendly term, a stye. Other related terms include external hordeolum and internal hordeolum, depending on the specific gland affected.

What is Hordeolum? An ICD-11 Overview

Hordeolum, identified by the ICD-11 code 9A01.2, is an acute focal infection affecting the glands of the eyelid. Typically caused by bacteria, most commonly Staphylococcus aureus, it involves either the eyelash follicle (external hordeolum) or the meibomian glands (internal hordeolum). This condition presents as an inflamed, often painful, localised infection.

Factors Contributing to Hordeolum Development

The primary cause of hordeolum is bacterial infection, predominantly Staphylococcus aureus, which affects the sebaceous or meibomian glands of the eyelid. Several factors can increase an individual's susceptibility:

• Poor eyelid hygiene.
• Using old or contaminated eye makeup.
• Wearing contact lenses, especially with inadequate hygiene.
• Pre-existing eyelid inflammation, such as blepharitis.
• Certain systemic conditions like rosacea or diabetes.

Recognising the Signs: Symptoms of a Stye

A hordeolum typically manifests with several noticeable symptoms, including:

• Pain, swelling, and redness at the edge of the eyelid.
• A tender, pus-filled lump or pimple-like appearance.
• A sensation of having a foreign body in the eye.
• Excessive tearing.
• Crusting along the eyelid margin.

Coding and Reporting Hordeolum: ICD-11 9A01.2

The ICD-11 code for Hordeolum is 9A01.2. This code is used for accurate medical record-keeping, billing, and statistical analysis. Specific types of hordeolum may be further specified using sub-codes, such as 9A01.20 for Hordeolum externum and 9A01.21 for Hordeolum internum. This ICD-11 code is billable and reportable for encounters related to the diagnosis and management of this condition.

Managing Hordeolum: Treatment and Prevention Strategies

While hordeolum often resolves on its own, medical intervention may be necessary. Treatment strategies focus on reducing inflammation and clearing the infection:

• Warm Compresses: Applying a warm, moist cloth to the affected eyelid for several minutes, multiple times a day, can help promote drainage.
• Antibiotics: Prescribed antibiotic ointments, drops, or sometimes oral medications are used to combat the bacterial infection.
• Avoid Squeezing: It is crucial not to attempt to squeeze or drain the stye, as this can worsen the infection or spread it.
• Hygiene Practices: Maintaining good eyelid hygiene, removing makeup before sleep, and regular hand washing are key preventive measures.
• Discontinuation of Makeup/Contacts: Patients are often advised to avoid eye makeup and contact lens wear until the infection has fully healed.

Consulting an eye care professional is recommended for proper diagnosis and treatment guidance.
