ICD-10 Code H10.823 – Rosacea conjunctivitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.823 – Rosacea conjunctivitis, bilateral
What it is
H10.823 identifies rosacea-related inflammation of both conjunctivae. Use it when documentation states bilateral rosacea conjunctivitis or ocular rosacea affecting both eyes.
Clinical signs
Findings may include conjunctival redness, irritation, tearing, burning, and eyelid margin inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rosacea conjunctivitis in both eyes, or bilateral ocular involvement linked to rosacea. It is appropriate for ophthalmology or primary care notes that clearly identify the condition as bilateral.
If the record only says rosacea, dry eye, or nonspecific conjunctivitis, do not assume this code. Check documentation for explicit bilateral conjunctival involvement.
Do not use for
Do not use it for unilateral rosacea conjunctivitis or for conjunctivitis without a rosacea link. Check documentation.
Coding tip
Capture the laterality exactly as documented; bilateral disease requires H10.823, not an unspecified or unilateral conjunctivitis code.
