ICD-10 Code H16.222 – Keratoconjunctivitis sicca, not specified as Sjögren’s, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.222 – Keratoconjunctivitis sicca, not specified as Sjögren’s, left eye
What it is
H16.222 identifies dry eye disease affecting the left eye, when the chart does not link it to Sjögren’s syndrome. Use it for keratoconjunctivitis sicca documented as non-Sjögren’s and unilateral.
Clinical signs
Typical findings include ocular dryness, burning, foreign-body sensation, redness, and irritation. Clinical features vary; refer to documentation for laterality and whether the condition is specifically non-Sjögren’s.
When to use this code
Use this code when the provider documents keratoconjunctivitis sicca or dry eye limited to the left eye and explicitly states it is not due to Sjögren’s syndrome. It also fits when the record supports left-sided dry eye without a Sjögren’s link. Check documentation if laterality or cause is unclear.
Do not use for
Do not use it for dry eye associated with Sjögren’s syndrome or when the affected eye is not documented as left. If the chart only says “dry eye” without further detail, check documentation.
Coding tip
Confirm both laterality and the “not specified as Sjögren’s” wording before assigning H16.222.
