H44.001 Unspecified purulent endophthalmitis, right eye

Name of the Condition

• Unspecified Purulent Endophthalmitis, Right Eye

Summary

Unspecified purulent endophthalmitis, right eye, is a severe intraocular infection involving the right 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 right 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 right eye.
• Penetrating eye trauma to the right eye.
• Immunocompromised states (e.g., diabetes, HIV, or immunosuppressive therapy).
• Pre-existing ocular infections or inflammation in the right eye.
• Use of intraocular devices or implants in the right eye.

Symptoms

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

Diagnosis

Diagnosis is based on clinical evaluation, including a detailed eye examination and history of recent procedures or trauma involving the right eye. Slit-lamp examination may reveal anterior chamber inflammation, and ultrasound or optical coherence tomography (OCT) may be used to assess intraocular structures. Cultures of ocular fluids or samples may identify the causative organism.

Treatment Options

• Antimicrobial Therapy: Intravitreal or systemic antibiotics/antifungals to target the infection.
• Surgical Intervention: Vitrectomy to remove infected vitreous and debris, often combined with intravitreal antibiotics.
• Adjunctive Treatments: Anti-inflammatory medications (e.g., corticosteroids) to reduce inflammation, and pain management as needed.
• Monitoring: Close follow-up to assess response to treatment and adjust therapy.

Prognosis and Follow-Up

Prognosis depends on the timeliness of treatment and the severity of the infection. Early intervention improves outcomes, but vision loss may still occur. Follow-up includes regular eye examinations to monitor for complications, such as retinal detachment or chronic inflammation, and to assess visual recovery.

Complications

• Permanent vision loss or blindness in the right eye.
• Retinal detachment.
• Chronic intraocular inflammation (uveitis).
• Cataract formation.
• Spread of infection to other parts of the eye or systemic involvement.

Lifestyle & Prevention

• Avoid eye trauma by using protective eyewear during activities with risk of injury.
• Follow postoperative care instructions strictly after eye surgery to reduce infection risk.
• Manage systemic conditions (e.g., diabetes) to support immune function.
• Seek prompt treatment for any ocular infections or injuries to prevent progression.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden severe eye pain, vision loss, or redness in the right eye, especially after surgery or trauma. Early evaluation is critical to prevent permanent damage.

Tips for Medical Coders

When coding H44.001, ensure the documentation specifies the right eye and the presence of purulent endophthalmitis without further localization or etiology. Verify that the condition is not better described by a more specific code (e.g., if the location or cause is documented). Confirm laterality and the absence of additional details to justify the "unspecified" designation.
