Iridodialysis, unspecified eye

This code signifies a detachment of the iris from its ciliary body attachment, specifically when the affected eye is not documented. This condition can result in symptoms such as monocular diplopia, photophobia, and glare due to the displaced iris tissue. It often occurs due to blunt ocular trauma.

Use this code when the patient presents with a diagnosis of iridodialysis and the medical record does not specify whether the right or left eye is affected. This code is appropriate when the documentation clearly indicates the presence of iridodialysis but lacks laterality.

• Always attempt to clarify laterality (right or left eye) with the provider to use a more specific code.
• If trauma is the cause, sequence the appropriate external cause code (V00-Y99) after this diagnosis code.
• Avoid using this code if the documentation specifies the affected eye; instead, use H21.531 (right eye) or H21.532 (left eye).
