H34.8112 Central retinal vein occlusion, right eye, stable

ICD10CM code

#### Name of the Condition
- Central Retinal Vein Occlusion, Right Eye, Stable (ICD-10: H34.8112)

#### Summary
- Central retinal vein occlusion (CRVO) occurs when the main vein responsible for draining blood from the retina becomes blocked. This condition can lead to vision problems or loss, primarily affecting one eye. In this case, the right eye is affected but is currently stable, meaning there is no immediate progression in symptoms.

#### Causes
- CRVO is often caused by a blood clot in the vein. Risk factors such as high blood pressure, diabetes, glaucoma, and atherosclerosis can contribute to the development of this blockage. It may also be associated with blood disorders or inflammatory diseases.

#### Risk Factors
- Age (more common in people over 50)
- High blood pressure
- Diabetes
- Smoking
- High cholesterol levels
- Glaucoma
- Conditions that affect blood flow, like atherosclerosis

#### Symptoms
- Sudden but painless loss of vision in one eye
- Blurry or distorted vision
- Dark spots or floaters in the vision

#### Diagnosis
- Eye examination and visual acuity tests
- Optical coherence tomography (OCT) to look for retinal swelling
- Fluorescein angiography to examine blood circulation in the retina

#### Treatment Options
- Intravitreal injections to reduce macular edema
- Laser therapy to prevent further vision loss
- Managing underlying conditions like hypertension and diabetes to improve overall eye health

#### Prognosis and Follow-Up
- With appropriate treatment, some patients regain partial vision. Regular follow-up appointments are crucial to monitor the condition for any changes or complications.
- Ongoing management of related systemic conditions can improve outcomes.

#### Complications
- Chronic vision loss or blindness if untreated
- Increased risk of developing neovascular glaucoma, a type of glaucoma associated with new, abnormal blood vessel growth

#### Lifestyle & Prevention
- Maintain a healthy lifestyle with regular exercise and a balanced diet to manage blood pressure and cholesterol
- Quit smoking and limit alcohol consumption
- Regular eye exams for early detection and treatment of asymptomatic conditions

#### When to Seek Professional Help
- Sudden vision changes or loss
- New or worsening symptoms despite stable condition

#### Additional Resources
- American Academy of Ophthalmology (www.aao.org)
- Retina specialized patient support groups and networks

#### Tips for Medical Coders
- Ensure documentation clearly specifies which eye is affected and the stability of the condition
- Avoid common coding errors such as misidentifying the laterality or mixing CRVO with branch retinal vein occlusion
