Degeneration of pupillary margin, bilateral

This code signifies a degenerative change affecting the rim of the pupil in both eyes. This condition involves structural deterioration of the pupillary border, which can impact pupillary function and light regulation. It is a non-inflammatory process leading to a breakdown of the tissue at the pupillary margin.

Apply this code when documentation explicitly states bilateral degeneration of the pupillary margin. This is typically diagnosed during an ophthalmologic examination, often noted as part of an anterior segment assessment. Supporting documentation should clearly indicate the presence and bilaterality of this specific degenerative process.

• Ensure documentation specifies "degeneration" and not another pupillary anomaly like atrophy or synechiae.
• Confirm the condition is present in both eyes; unilateral involvement would require a different code.
• Do not confuse with codes for iris atrophy or other iris disorders, as this code is specific to the pupillary margin.
