Conjunctival xerosis, unspecified, left eye

This code signifies a condition of dryness of the conjunctiva, the membrane lining the eyelids and covering the white part of the eye, specifically affecting the left eye. This dryness is not further specified as to its underlying cause or specific type.

Use this code when documentation indicates conjunctival xerosis of the left eye without further specificity regarding its etiology (e.g., due to vitamin A deficiency, exposure, or other systemic conditions). This is appropriate when the physician has diagnosed dryness of the conjunctiva but has not identified a more precise form of xerosis.

• Ensure the documentation clearly specifies the left eye; otherwise, an unspecified eye code or bilateral code may be more appropriate.
• Avoid using this code if a more specific type of conjunctival xerosis (e.g., due to vitamin A deficiency, H11.10-) is documented.
• Always review for any underlying systemic conditions that may be causing the xerosis, as these may require additional coding.
