Keratomalacia, bilateral

This code signifies a severe drying and clouding of the cornea in both eyes, often leading to corneal ulceration and potential blindness. It is primarily caused by severe vitamin A deficiency, which impairs the normal function of the conjunctiva and cornea.

Apply this code when documentation clearly indicates bilateral corneal softening and opacification due to malnutrition, specifically vitamin A deficiency. Supporting documentation should include ophthalmological findings consistent with keratomalacia affecting both eyes.

• Differentiate from other corneal opacities; this code is specific to the softening and drying process.
• Always code an underlying cause, such as E50.6 (Vitamin A deficiency with xerophthalmia, unspecified), if known and documented.
• Ensure documentation specifies "bilateral" involvement to support this specific code, as unilateral codes exist.
