H44.002 Unspecified purulent endophthalmitis, left eye

Name of the Condition

• Unspecified Purulent Endophthalmitis, Left Eye

Summary

Unspecified purulent endophthalmitis, left eye, is a severe intraocular infection involving the left eye, marked by the presence of pus within the eye, typically affecting the vitreous or aqueous humor. It is a sight-threatening condition that requires immediate medical attention to prevent permanent vision loss. The term "unspecified" indicates that the specific location or cause of the infection is not detailed in the documentation, and the laterality is specified as the left eye.

Causes

The condition is most commonly caused by bacterial or fungal infections, which may enter the eye through trauma, surgery, or systemic spread. Postoperative infections, particularly after cataract or retinal surgery, are a frequent cause. Less commonly, it may result from endogenous sources, such as septicemia. The unspecified nature of the code suggests the documentation does not specify the exact etiology or location.

Risk Factors

• Recent eye surgery (e.g., cataract, glaucoma, or retinal procedures) involving the left eye.
• Penetrating eye trauma to the left eye.
• Immunocompromised states (e.g., diabetes, HIV, or immunosuppressive therapy).
• Pre-existing ocular infections or inflammation in the left eye.
• Use of intraocular devices or implants in the left eye.

Symptoms

• Sudden, severe eye pain.
• Marked decrease in vision or vision loss.
• Redness and swelling of the eye.
• Sensitivity to light (photophobia).
• Discharge or pus visible in the eye.
• Floaters or a "cobweb" sensation in the visual field.

Diagnosis

Diagnosis is based on clinical evaluation, including a detailed eye examination and history of recent procedures or trauma. Slit-lamp examination may reveal anterior chamber inflammation, hypopyon, or vitreous haze. Ultrasound or optical coherence tomography (OCT) may be used to assess intraocular structures. Cultures of aqueous or vitreous samples may identify the causative organism, though this is not always performed.

Treatment Options

Treatment typically involves urgent administration of intravitreal antibiotics or antifungals, often guided by culture results. Topical, subconjunctival, or systemic antimicrobial therapy may be added. In severe cases, pars plana vitrectomy (surgical removal of vitreous) may be necessary to clear infection and reduce inflammation. Corticosteroids may be used to control inflammation, but timing depends on infection control.

Prognosis and Follow-Up

Prognosis depends on the severity of infection, timeliness of treatment, and underlying health. Vision loss may be permanent, especially if treatment is delayed. Follow-up includes close monitoring of visual acuity, intraocular pressure, and inflammation. Repeat imaging or cultures may be needed if symptoms persist or worsen.

Complications

• Permanent vision loss or blindness.
• Retinal detachment.
• Cataract formation.
• Glaucoma.
• Phthisis bulbi (shrinkage of the eye).

Lifestyle & Prevention

• Avoid eye trauma by using protective eyewear.
• Ensure sterile techniques during eye surgery.
• Manage systemic conditions like diabetes to reduce infection risk.
• Seek prompt treatment for ocular infections or injuries.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden severe eye pain, vision loss, or redness, especially after surgery or trauma. Do not delay care, as early treatment improves outcomes.

Tips for Medical Coders

Document the laterality (left eye) and the unspecified nature of the infection. Ensure the medical record supports the diagnosis without specifying the exact location or cause, as the code H44.002 is used when these details are not documented. Verify that the code aligns with the clinical findings and avoid using more specific codes if documentation is incomplete.
