H31.31 Expulsive choroidal hemorrhage

Name of the Condition

• Expulsive Choroidal Hemorrhage (ICD Code: H31.31)

Summary

Expulsive choroidal hemorrhage is a severe form of bleeding within the choroid, the vascular layer of the eye, often associated with intraocular surgery or trauma. This condition can lead to sudden vision loss and structural damage to the eye, requiring prompt medical attention to manage complications and preserve visual function.

Causes

Expulsive choroidal hemorrhage typically occurs during or after intraocular procedures, such as cataract surgery, due to sudden changes in intraocular pressure. It may also result from direct trauma to the eye, which disrupts the choroidal vasculature and causes rapid hemorrhage.

Risk Factors

• Intraocular surgery (e.g., cataract extraction)
• Severe eye trauma
• Pre-existing vascular disease (e.g., hypertension)
• Advanced age
• Use of anticoagulant medications
• Prolonged surgical time or intraoperative complications

Symptoms

• Sudden, severe vision loss
• Eye pain or pressure
• Protrusion of intraocular contents (e.g., iris, lens)
• Hemorrhage visible in the anterior or posterior segment
• Nausea or vomiting (due to pain)

Diagnosis

Diagnosis involves a thorough clinical examination, including assessment of intraocular pressure and visualization of the hemorrhage. Imaging studies like B-scan ultrasonography may be used to evaluate the extent of bleeding and structural damage when direct visualization is limited.

Treatment Options

Treatment focuses on immediate surgical intervention to control bleeding and repair any prolapsed tissue. Supportive care, such as intraocular pressure management and anti-inflammatory medications, may be necessary to stabilize the eye and prevent further damage.

Prognosis and Follow-Up

Prognosis depends on the severity of the hemorrhage and the timeliness of treatment. Vision recovery is often limited, and long-term follow-up with an ophthalmologist is essential to monitor for complications like glaucoma or retinal detachment.

Complications

• Permanent vision loss
• Glaucoma
• Retinal detachment
• Phthisis bulbi (shrinkage of the eye)
• Infection

Lifestyle & Prevention

• Avoid activities that risk eye injury (e.g., contact sports).
• Manage systemic conditions like hypertension to reduce vascular fragility.
• Follow postoperative care instructions after eye surgery to minimize complications.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden vision loss, severe eye pain, or visible bleeding in the eye, especially after surgery or trauma.

Tips for Medical Coders

Document the clinical context (e.g., surgery, trauma) and any associated procedures. Ensure the code H31.31 is used when the hemorrhage is expulsive, as opposed to unspecified or non-expulsive forms. Include details about the eye affected and any contributing factors to support accurate coding.
