ICD-10 Code H04 – Disorders of lacrimal system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04 – Disorders of lacrimal system
What it is
H04 covers disorders affecting the tear drainage and lacrimal structures around the eye. Use it for conditions involving blocked, inflamed, or otherwise abnormal lacrimal passages or glands.
Clinical signs
Common findings include tearing, eye irritation, discharge, or swelling near the inner corner of the eye. Clinical features vary; refer to documentation.
When to use this code
Use H04 when the provider documents a lacrimal system disorder without a more specific diagnosis. It may apply to obstruction, inflammation, or other documented abnormality of the tear drainage system. Confirm whether the record identifies a specific subcategory before coding.
Do not use for
Do not use this code for general eye redness, conjunctival disease, or eyelid conditions unless the lacrimal system is specifically involved. Check documentation.
Coding tip
Look for the exact lacrimal site and type of disorder, then code the most specific H04 option available.
