ICD-10 Code H10.532 – Contact blepharoconjunctivitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.532 – Contact blepharoconjunctivitis, left eye
What it is
This code identifies inflammation of the left eyelid and conjunctiva caused by contact with an irritant or allergen. Use it when the documentation specifies the left eye and a contact-related cause.
Clinical signs
Typical findings include redness, itching, tearing, eyelid swelling, and conjunctival irritation. Clinical features vary; refer to documentation for the exact cause and laterality.
When to use this code
Use H10.532 when the provider documents contact blepharoconjunctivitis affecting the left eye. It fits cases linked to exposure such as cosmetics, chemicals, plants, or other irritants when the record supports a contact reaction.
If the note only says conjunctivitis or eye irritation without laterality or contact cause, check documentation before assigning this code. Make sure the left eye is clearly identified.
Do not use for
Do not use this code for infectious conjunctivitis, allergic conjunctivitis without contact exposure, or unspecified eye inflammation. Check documentation if the chart does not confirm contact-related disease.
Coding tip
Assign the code only when both contact etiology and left-eye laterality are documented.
