ICD-10 Code H21.532 – Iridodialysis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H21.532 – Iridodialysis, left eye
What it is
Iridodialysis is a separation of the iris from its attachment at the ciliary body. This code specifies the left eye.
Clinical signs
Findings may include a visible iris root tear, irregular pupil shape, glare, or monocular diplopia. Clinical features vary; refer to documentation.
When to use this code
Use H21.532 when the record clearly documents iridodialysis in the left eye. Apply it for traumatic or postoperative cases only if the provider identifies the condition by name.
Code it when laterality is confirmed and the separation is in the left eye. Check documentation if the note describes an iris injury without naming iridodialysis.
Do not use for
Do not use this code for unspecified eye laterality or for other iris disorders such as coloboma or synechiae. Check documentation if the diagnosis is not explicit.
Coding tip
Verify that the provider states “iridodialysis” and “left eye” together before assigning H21.532.
