H44.003 Unspecified purulent endophthalmitis, bilateral

Name of the Condition

• Unspecified Purulent Endophthalmitis, Bilateral

Summary

Unspecified purulent endophthalmitis, bilateral, is a severe intraocular infection affecting both eyes, marked by the presence of pus within the eye, typically involving 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 condition is bilateral (affecting both eyes).

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 both eyes.
• Penetrating eye trauma to both eyes.
• Immunocompromised states (e.g., diabetes, HIV, or immunosuppressive therapy).
• Pre-existing ocular infections or inflammation in both eyes.
• Use of intraocular devices or implants in both eyes.

Symptoms

• Sudden, severe eye pain in both eyes.
• Marked decrease in vision or vision loss in both eyes.
• Redness and swelling of both eyes.
• Sensitivity to light (photophobia) in both eyes.
• Discharge or pus visible in one or both eyes.

Diagnosis

Diagnosis involves a thorough eye examination, including visual acuity testing, slit-lamp examination, and possibly imaging studies like ultrasound or optical coherence tomography (OCT). Cultures of ocular fluids (e.g., aqueous or vitreous humor) may be obtained to identify the causative organism. The unspecified nature of the code indicates that the documentation does not specify the exact etiology or location of the infection.

Treatment Options

Treatment typically includes intravitreal antibiotics or antifungals, often administered via injection directly into the eye. Systemic antibiotics or antifungals may be used for severe or systemic infections. In some cases, surgical intervention, such as a vitrectomy, may be necessary to remove infected tissue and pus. The choice of treatment depends on the severity and underlying cause of the infection.

Prognosis and Follow-Up

Prognosis depends on the promptness of treatment and the severity of the infection. Early intervention improves the chances of preserving vision, but permanent vision loss can occur. Follow-up care is essential to monitor for recurrence or complications, and regular eye examinations are recommended to assess visual recovery.

Complications

• Permanent vision loss or blindness.
• Retinal detachment.
• Cataract formation.
• Glaucoma.
• Spread of infection to other parts of the eye or body.

Lifestyle & Prevention

• Avoid eye trauma by using protective eyewear during activities with a risk of injury.
• Follow postoperative care instructions after eye surgery to reduce infection risk.
• Manage underlying conditions like diabetes to support immune function.
• Seek prompt treatment for any eye infections or injuries.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden severe eye pain, vision loss, or redness in both eyes, as these may indicate a serious infection requiring urgent care.

Tips for Medical Coders

When coding for unspecified purulent endophthalmitis, bilateral (H44.003), ensure the documentation supports the bilateral nature of the condition and the unspecified status of the infection. Verify that the term "unspecified" is used consistently in the medical record to reflect the lack of detailed etiology or location. Confirm that the laterality is clearly documented as bilateral to justify the code selection.
