ICD-10 Code H10.822 – Rosacea conjunctivitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.822 – Rosacea conjunctivitis, left eye
What it is
Use this code for rosacea-related inflammation of the conjunctiva in the left eye. It identifies a unilateral ocular manifestation associated with rosacea, not general facial rosacea alone.
Clinical signs
Typical findings may include conjunctival redness, irritation, burning, tearing, and eyelid margin inflammation. Clinical features vary; refer to documentation.
When to use this code
Assign H10.822 when the provider documents rosacea conjunctivitis affecting only the left eye. Use it when the note clearly links conjunctival inflammation to rosacea and specifies laterality.
If the record only says “rosacea” without eye involvement, this code is not supported. Check documentation when laterality, ocular involvement, or the rosacea connection is unclear.
Do not use for
Do not use this code for unspecified conjunctivitis, bilateral disease, or rosacea limited to the skin. Check documentation if the eye condition is not clearly attributed to rosacea.
Coding tip
Verify both the rosacea association and left-eye laterality before assigning H10.822.
