ICD-10 Code H16.229 – Keratoconjunctivitis sicca, not specified as Sjögren’s, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.229 – Keratoconjunctivitis sicca, not specified as Sjögren’s, unspecified eye
What it is
This code identifies dry eye disease affecting an unspecified eye when the record states keratoconjunctivitis sicca and does not link it to Sjögren’s syndrome. Use it when laterality is not documented.
Clinical signs
Typical findings include ocular dryness, irritation, burning, foreign-body sensation, and redness. Clinical features vary; refer to documentation for the recorded eye involved and any supporting exam findings.
When to use this code
Use H16.229 when the provider documents keratoconjunctivitis sicca or dry eye without specifying Sjögren’s syndrome and without identifying right or left eye. It also fits cases where the note confirms dry eye but laterality is missing. Check documentation if the condition is described as bilateral or tied to another cause.
Do not use for
Do not use this code for dry eye due to Sjögren’s syndrome or when the record specifies another eye laterality. If the diagnosis is unclear, check documentation.
Coding tip
Confirm both etiology and laterality in the note before assigning H16.229.
