H35.032 Hypertensive retinopathy, left eye

ICD10CM code

#### Name of the Condition
- Hypertensive Retinopathy, Left Eye
- Medical term: Hypertensive retinopathy

#### Summary
Hypertensive retinopathy is an eye condition that occurs due to high blood pressure, affecting the retinal blood vessels, specifically in the left eye. It can lead to changes in vision, and if untreated, may cause severe eye problems.

#### Causes
The primary cause of hypertensive retinopathy is chronic high blood pressure (hypertension), which damages the blood vessels in the retina.

#### Risk Factors
- Persistent high blood pressure
- Diabetes
- High cholesterol levels
- Smoking
- Age (greater risk as people get older)

#### Symptoms
- Blurred vision
- Double vision
- Eye pain or discomfort
- Reduced vision

#### Diagnosis
- Comprehensive eye examination
- Fundoscopic examination (using an ophthalmoscope to check the retina)
- Blood pressure measurement
- Fluorescein angiography (in some cases)

#### Treatment Options
- Control and management of high blood pressure through medications such as antihypertensives
- Lifestyle changes like diet and exercise
- Regular monitoring of blood pressure and eye health

#### Prognosis and Follow-Up
With effective blood pressure control, the damage can be stabilized, preventing further deterioration. However, regular follow-ups with both an ophthalmologist and a primary care physician are essential.

#### Complications
- Progressive vision loss
- Retinal artery or vein occlusion
- Macular edema or retinal detachment

#### Lifestyle & Prevention
- Maintain a healthy diet low in salt
- Regular physical activity
- Avoiding smoking and excessive alcohol consumption
- Regular health screenings to monitor blood pressure

#### When to Seek Professional Help
Seek immediate medical attention if there is a sudden change in vision, severe headache, or if you experience signs of very high blood pressure (e.g., chest pain, shortness of breath).

#### Tips for Medical Coders
- Ensure specificity in coding whether the condition affects the left, right, or both eyes.
- Verify the diagnosis with medical documentation to avoid incorrect coding of other eye conditions.
