Vitamin A deficiency with corneal ulceration and xerosis

This code signifies a severe form of vitamin A deficiency characterized by ocular manifestations, specifically corneal ulceration and xerosis. Corneal ulceration involves a defect in the corneal epithelium, while xerosis refers to abnormal dryness of the conjunctiva and cornea due to vitamin A deficiency. These conditions can lead to permanent vision impairment or blindness if left untreated.

This code is appropriate when documentation clearly indicates a diagnosis of vitamin A deficiency alongside clinical findings of both corneal ulceration and xerosis. It should be used for patients presenting with eye symptoms directly attributable to vitamin A deficiency, confirmed by clinical examination and/or laboratory findings.

• Ensure documentation specifies both corneal ulceration and xerosis; if only one is present, a different code may be more appropriate.
• Consider sequencing this code as a primary diagnosis if the vitamin A deficiency with these ocular complications is the main reason for the encounter.
• Look for supporting documentation such as ophthalmology reports, nutritional assessments, and laboratory results confirming vitamin A deficiency.
