Vitamin A deficiency with keratomalacia

This code signifies a nutritional deficiency characterized by insufficient vitamin A, specifically manifesting with keratomalacia. Keratomalacia is a severe eye condition involving drying and ulceration of the cornea, often leading to blindness, directly resulting from prolonged vitamin A deficiency. It represents a late and severe stage of vitamin A deficiency affecting ocular health.

Utilize this code when documentation explicitly states a diagnosis of vitamin A deficiency and specifies the presence of keratomalacia. This typically occurs in cases of severe malnutrition, malabsorption syndromes, or dietary inadequacy where the eye is significantly impacted. Supporting documentation should include ophthalmological findings confirming corneal involvement consistent with keratomalacia.

• Ensure the documentation clearly links the keratomalacia to the vitamin A deficiency; otherwise, a separate code for keratomalacia (e.g., H16.4x) might be more appropriate.
• Consider co-reporting codes for underlying causes of vitamin A deficiency, such as malnutrition (e.g., E40-E46) or malabsorption (e.g., K90.xx), if documented.
• Differentiate from other forms of vitamin A deficiency without keratomalacia, such as E50.0 (with conjunctival xerosis) or E50.2 (with night blindness).
