Degeneration of pupillary margin, right eye

This code describes a degenerative change affecting the pupillary border of the iris in the right eye. This can involve atrophy, thinning, or other structural alterations of the iris tissue specifically at its inner edge, which forms the pupil.

Use this code when documentation specifies degeneration of the pupillary margin, clearly indicating the right eye. This is often observed during slit lamp examination and may be associated with conditions like pseudoexfoliation syndrome or age-related changes.

• Ensure laterality is explicitly documented as "right eye" to support this specific code.
• Distinguish from other iris degenerations not specifically affecting the pupillary margin.
• Code any underlying or associated conditions, such as glaucoma or pseudoexfoliation, in addition to this code.
