ICD-10-CM Billable Code

H35.059

Retinal neovascularization, unspecified, unspecified eye

Clinical Classification Guidelines

Medical Intelligence & Overview

Retinal neovascularization refers to the abnormal growth of new blood vessels on the retina, the light-sensitive tissue at the back of the eye. This condition can affect either eye and is often linked to underlying eye diseases or systemic health issues. If left untreated, retinal neovascularization may lead to vision impairment or loss. Recognizing the signs and seeking appropriate medical care are vital steps in managing this condition effectively.

Causes & Symptoms

Clinical Causes: Diabetic retinopathy: High blood sugar levels damage retinal blood vessels, prompting abnormal growth. Retinal vein occlusion: Blockage of retinal veins can reduce blood flow, encouraging new vessel formation as a response. Ocular ischemic syndrome: Poor blood supply to the eye causes the retina to produce new vessels in an attempt to improve oxygen delivery. Degenerative retinal disorders: Conditions such as retinopathy of prematurity or other ischemic retinal diseases. Inflammatory eye conditions: Chronic inflammation can stimulate abnormal vessel growth.

Key Symptoms: Sudden or gradual loss of vision Blurred or distorted vision Floaters or cobweb-like visual disturbances Dark patches or spots in the visual field In some cases, no noticeable symptoms until significant damage has occurred

Diagnostic & Treatment

Diagnosis Path: Diagnosis of retinal neovascularization typically involves a comprehensive eye examination, including:

Treatment Protocols: Managing retinal neovascularization involves addressing both the abnormal blood vessels and their underlying causes. Common treatment options include:
