H00.14 Chalazion left upper eyelid

Name of the Condition

• Chalazion left upper eyelid

Summary

A chalazion left upper eyelid is a small, benign lump or swelling in the left upper eyelid caused by a blocked oil gland. It is typically painless and may resolve on its own over time.

Causes

It results from the obstruction and inflammation of the meibomian glands, which are responsible for oil (sebaceous) secretion in the eyelids. This blockage can lead to the formation of a localized lipogranuloma.

Risk Factors

• Chronic blepharitis (eyelid inflammation)
• Previous history of chalazia
• Skin conditions like rosacea or seborrheic dermatitis
• Frequent eye rubbing or poor eyelid hygiene

Symptoms

• Raised, painless bump on the left upper eyelid
• Mild irritation or discomfort
• Possible localized redness or swelling
• Blurred vision if the chalazion is large enough to press on the eyeball

Diagnosis

Physical examination by a healthcare professional is typically sufficient to diagnose a chalazion. Differential diagnosis may be performed to rule out other eyelid lesions or tumors.

Treatment Options

• Warm compresses applied several times a day to aid drainage
• Gentle eyelid massage to promote drainage
• Topical antibiotic or anti-inflammatory ointments prescribed if inflammation is present
• Surgical incision and drainage if conservative treatments fail and the chalazion persists

Prognosis and Follow-Up

Most chalazia resolve on their own in weeks to months. Follow-up may be recommended if the lesion persists or recurs.

Complications

• Persistent swelling or recurrence
• Secondary infection
• Cosmetic concerns due to visible lump

Lifestyle & Prevention

• Maintain good eyelid hygiene with gentle cleansing
• Avoid rubbing the eyes
• Manage underlying conditions like blepharitis or rosacea
• Use warm compresses regularly if prone to chalazia

When to Seek Professional Help

Seek care if the lump becomes painful, grows larger, affects vision, or shows signs of infection (e.g., increased redness, pus).

Tips for Medical Coders

Use H00.14 for a chalazion specifically located on the left upper eyelid. Document the eyelid location and laterality clearly in the medical record to support code assignment.
