ICD-10 Code H16.223 – Keratoconjunctivitis sicca, not specified as Sjögren’s, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.223 – Keratoconjunctivitis sicca, not specified as Sjögren’s, bilateral
What it is
This code identifies dry eye disease affecting both eyes when the record does not link it to Sjögren’s syndrome. It reflects reduced tear film support of the ocular surface.
Clinical signs
Common findings include ocular dryness, burning, foreign-body sensation, and irritation. Clinical features vary; refer to documentation for bilateral involvement and whether Sjögren’s is excluded.
When to use this code
Use H16.223 when the clinician documents keratoconjunctivitis sicca in both eyes and specifically states it is not due to Sjögren’s syndrome. You may also use it when the note clearly separates dry eye from autoimmune sicca disease. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for dry eye linked to Sjögren’s syndrome or when only one eye is affected. If the record is nonspecific about cause or laterality, check documentation.
Coding tip
Verify both laterality and the “not specified as Sjögren’s” wording before assigning H16.223.
