Degeneration of iris (pigmentary), bilateral

This code signifies a degenerative condition affecting the iris, specifically involving pigmentary changes, in both eyes. It describes a breakdown or loss of pigment within the iris tissue, which can lead to various ocular symptoms.

Apply this code when documentation clearly indicates bilateral pigmentary degeneration of the iris. This is often seen in conditions like pigment dispersion syndrome or pigmentary glaucoma, where pigment granules are shed from the iris. Supporting documentation should include ophthalmological exam findings noting bilateral iris transillumination defects or pigment deposition.

• Ensure documentation specifies "pigmentary" degeneration and not other forms of iris degeneration.
• Verify laterality; this code is specifically for bilateral involvement.
• Consider co-reporting with codes for associated conditions like pigmentary glaucoma (H40.13x) if present.
