Peripheral corneal degeneration, right eye

This code signifies a non-inflammatory thinning or deterioration of the peripheral cornea in the right eye. This degeneration can manifest as various conditions, such as Terrien's marginal degeneration or furrow degeneration, leading to changes in corneal shape and potentially vision.

Apply this code when documentation specifies a diagnosis of peripheral corneal degeneration affecting the right eye. This typically includes findings of corneal thinning, lipid deposition, or vascularization in the peripheral cornea, as noted by an ophthalmologist.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Distinguish from central corneal degenerations (e.g., keratoconus) which have different code assignments.
• Do not use for inflammatory conditions of the peripheral cornea, such as peripheral ulcerative keratitis.
