Conjunctival xerosis, unspecified, bilateral

This code describes a condition characterized by abnormal dryness of the conjunctiva, the membrane lining the eyelids and covering the white part of the eye, affecting both eyes. This dryness is due to a deficiency in the tear film, leading to irritation and discomfort. The specific cause of the xerosis is not identified.

Use this code when documentation indicates bilateral conjunctival xerosis without specifying the underlying etiology. This applies when the physician notes dry eyes affecting both sides, but further investigation into the cause (e.g., vitamin A deficiency, Sjogren's syndrome) has not been performed or is not documented.

• Ensure documentation explicitly states "bilateral" and "unspecified" regarding the cause.
• If the laterality is specified as right or left, or if a specific cause is identified (e.g., due to vitamin A deficiency), a more specific code should be used.
• Do not confuse with codes for dry eye syndrome (H04.12-) unless the documentation specifically points to conjunctival xerosis.
