ICD-10-CM Billable Code

H16.403

Unspecified corneal neovascularization, bilateral

Clinical Classification Guidelines

Medical Intelligence & Overview

Corneal neovascularization refers to the abnormal growth of new blood vessels into the cornea, the clear front surface of the eye. When this occurs on both eyes, it's termed bilateral corneal neovascularization. This condition can affect vision quality and may be a sign of underlying eye health issues. The ICD-10 code H16.403 specifically describes cases where the neovascularization is unspecified in terms of severity or cause, occurring in both eyes.

Causes & Symptoms

Clinical Causes: Chronic ocular surface inflammation Severe eye infections Corneal injuries or trauma Contact lens overuse or misuse Corneal hypoxia (lack of oxygen), often due to prolonged contact lens wear Corneal ulcers or other corneal diseases Previous eye surgeries or procedures Environmental factors such as exposure to harmful chemicals or UV light Underlying systemic conditions like inflammatory or autoimmune diseases

Key Symptoms: Blurred or decreased vision Redness and redness spread across both eyes Sensitivity to light (photophobia) Feeling of a foreign body in the eye Tearing or watering of the eyes Discomfort, ache, or a gritty sensation in the eyes Visible blood vessels in the cornea on slit-lamp examination Possible discharge or infection signs in some cases

Diagnostic & Treatment

Diagnosis Path: Diagnosis typically involves a comprehensive eye examination by an ophthalmologist, including slit-lamp biomicroscopy to visualize the cornea and detect abnormal blood vessels. Additional tests may include corneal photography or fluorescein staining to assess the extent of neovascularization. The healthcare provider will also review the patient's medical history and ocular surface condition to identify possible underlying causes.

Treatment Protocols: Management strategies aim to control or reverse neovascularization and treat underlying causes. Possible options include: - **Medical therapies**: Use of anti-inflammatory eye drops, corticosteroids, or medications to reduce inflammation. - **Laser treatment**: Laser photocoagulation to target and ablate abnormal blood vessels. - **Surgical options**: Corneal transplantation or procedures to remove neovascular tissue may be considered in severe cases. - **Addressing underlying factors**: Proper contact lens hygiene, treatment of infections, or managing autoimmune conditions. Preventing recurring neovascularization involves regular eye check-ups, adhering to prescribed treatments, and protecting the eyes from environmental hazards. It is essential for individuals with or at risk of corneal neovascularization to seek prompt professional care to prevent vision loss.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
