ICD-10 Code H21.531 – Iridodialysis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H21.531 – Iridodialysis, right eye
What it is
Iridodialysis is a tear or separation of the iris at its root from the ciliary body. This code specifies the right eye.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a visible iris defect, irregular pupil shape, and symptoms after eye trauma.
When to use this code
Use this code when the record documents iridodialysis in the right eye, usually after blunt trauma or another confirmed ocular injury. Code it when the provider clearly identifies the condition and laterality. If the note is vague, check documentation.
Do not use for
Do not use this code for unspecified eye laterality or for other iris injuries without documented iridodialysis. Check documentation if the finding is only suspected.
Coding tip
Verify laterality carefully; H21.531 applies only to the right eye.
