ICD-10 Code H10.53 – Contact blepharoconjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.53 – Contact blepharoconjunctivitis
What it is
H10.53 identifies inflammation of the conjunctiva and eyelids caused by contact with an irritant or allergen. Use it when the record shows a contact-related blepharoconjunctivitis rather than an infectious eye condition.
Clinical signs
Typical findings include red, itchy, watery eyes with eyelid irritation or swelling. Clinical features vary; refer to documentation for the specific trigger and whether both the conjunctiva and eyelids are involved.
When to use this code
Use this code when the provider documents contact blepharoconjunctivitis, allergic contact eye inflammation, or a similar contact reaction affecting the eyelids and conjunctiva. Code it when the note links the condition to exposure such as cosmetics, eye drops, or other irritants. Check documentation if the cause is not clearly stated.
Do not use for
Do not use it for simple conjunctivitis, blepharitis, or infectious eye disease unless contact blepharoconjunctivitis is specifically documented. If the record does not support a contact cause, check documentation.
Coding tip
Capture the documented trigger and laterality when available, because those details can support accurate coding and reporting.
