Vitamin A deficiency with corneal xerosis

This code signifies a nutritional deficiency of Vitamin A that has progressed to affect the eye, specifically causing dryness and thickening of the conjunctiva and cornea. This ocular manifestation is a direct consequence of inadequate Vitamin A intake or absorption, leading to impaired vision and potential blindness if untreated.

Apply this code when documentation clearly states a diagnosis of Vitamin A deficiency accompanied by corneal xerosis. This typically occurs in cases of malnutrition, malabsorption syndromes, or dietary restrictions. Supporting documentation should include ophthalmological findings confirming corneal dryness and thickening, along with evidence of Vitamin A deficiency.

• Ensure the documentation explicitly links the corneal xerosis to Vitamin A deficiency; otherwise, a general xerophthalmia code might be more appropriate.
• Consider sequencing this code after any underlying conditions causing the Vitamin A deficiency (e.g., malabsorption syndromes).
• Do not confuse with other forms of xerophthalmia not specifically attributed to Vitamin A deficiency.
