ICD-10 Code H04.121 – Dry eye syndrome of right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.121 – Dry eye syndrome of right lacrimal gland
What it is
This code identifies dry eye syndrome affecting the right lacrimal gland. It is used when the right eye has reduced tear production or tear film instability causing ocular dryness.
Clinical signs
Typical findings include eye dryness, burning, irritation, foreign-body sensation, and intermittent blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H04.121 when the provider documents dry eye syndrome specifically in the right lacrimal gland or right eye. It fits cases where the diagnosis is clearly unilateral and laterality is stated. If the record only says dry eye without laterality, check documentation.
Do not use for
Do not use this code for dry eye of the left eye, bilateral dry eye, or nonspecific dry eye without right-sided documentation. Check documentation if the note does not identify the affected side.
Coding tip
Always confirm laterality in the assessment or problem list before assigning H04.121.
