Deep vascularization of cornea, right eye

This code signifies the presence of abnormal, newly formed blood vessels that have grown deeply into the corneal stroma of the right eye. This condition, known as deep corneal vascularization, can impair vision by causing corneal opacification and can be a sequela of various corneal diseases or injuries.

Use this code when documentation explicitly states "deep vascularization of the cornea" affecting the right eye. This is often seen in chronic inflammatory conditions, severe infections, or after significant corneal trauma or surgery. Documentation should specify the depth of vascularization (deep vs. superficial) and the affected eye.

• Differentiate between deep and superficial vascularization; separate codes exist for superficial involvement.
• Ensure laterality is accurately documented and coded (right, left, or bilateral).
• Consider co-reporting underlying causes of the vascularization, such as corneal ulcers (H16.0-H16.2) or keratitis (H16.0-H16.9).
