Nodular corneal degeneration, unspecified eye

This code represents a chronic, non-inflammatory condition of the cornea characterized by the presence of nodular opacities. These nodules are typically elevated, grayish-white lesions that can affect visual acuity depending on their size and location. It is a form of corneal degeneration where the specific type or cause of the nodular changes is not documented.

Use this code when documentation indicates nodular corneal degeneration without further specification of the type (e.g., Salzmann's nodular degeneration) or the affected eye. This code is appropriate when the physician's diagnosis explicitly states "nodular corneal degeneration, unspecified eye" or similar terminology lacking laterality.

• Ensure documentation clearly states "unspecified eye" or lacks laterality for the nodular corneal degeneration.
• Avoid using this code if a more specific type of nodular corneal degeneration (e.g., Salzmann's) is documented; instead, use the appropriate specific code.
• If laterality is documented (right or left eye), select the corresponding laterality-specific code (H18.451 or H18.452).
