ICD-10 Code H10.829 – Rosacea conjunctivitis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.829 – Rosacea conjunctivitis, unspecified eye
What it is
H10.829 identifies rosacea conjunctivitis affecting an unspecified eye. Use it when the chart documents conjunctival inflammation linked to rosacea, but the laterality is not stated.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include eye redness, irritation, burning, tearing, and conjunctival inflammation in a patient with rosacea.
When to use this code
Use this code when the provider clearly documents rosacea conjunctivitis and does not specify right, left, or bilateral eye involvement. It is appropriate for outpatient, specialty, or consult notes that support the diagnosis.
If the record only mentions rosacea without ocular involvement, do not assign this code. Check documentation when the eye affected is unclear or when another eye disorder is the primary documented condition.
Do not use for
Do not use it for nonspecific conjunctivitis, blepharitis, or dry eye unless rosacea conjunctivitis is explicitly documented. Check documentation if the eye condition is due to another cause.
Coding tip
Verify both the rosacea link and the unspecified laterality before assigning H10.829.
