2026 ICD-10-CM Diagnosis Code H10.531 – Contact blepharoconjunctivitis, right eye
What it is
Use this code for inflammation of the right eyelid and conjunctiva caused by contact exposure. It indicates a localized irritative or allergic reaction affecting the right eye.
Clinical signs
Typical findings include redness, itching, tearing, eyelid swelling, and conjunctival irritation in the right eye. Clinical features vary; refer to documentation.
When to use this code
Use H10.531 when the record clearly documents contact blepharoconjunctivitis limited to the right eye. It is appropriate when the clinician identifies an external contact cause, such as exposure to an irritant or allergen, and specifies the right eye.
Do not use for
Do not use this code if the condition involves both eyes or the left eye only. Do not assign it when the documentation does not support contact-related conjunctival inflammation; check documentation.
Coding tip
Confirm both laterality and contact cause in the note before assigning H10.531.
