Iridoschisis, right eye

This code signifies a splitting or delamination of the iris stroma, specifically affecting the right eye. This condition often presents as fine, thread-like strands of iris tissue floating in the anterior chamber or attached to the corneal endothelium. It is typically a degenerative process, more common in older individuals.

Apply this code when documentation explicitly states a diagnosis of iridoschisis in the right eye. Supporting clinical notes should describe the characteristic splitting of the iris, often observed during a slit lamp examination. This code is appropriate for both initial diagnoses and subsequent encounters where the condition is being monitored or managed.

• Ensure laterality is clearly documented and accurately reflected in the code selection.
• Distinguish from iris atrophy (H21.21-) which involves thinning, not splitting, of the iris.
• Look for associated conditions like glaucoma (H40.-) or pseudoexfoliation syndrome (H21.5-) which may coexist with iridoschisis.
