    Corneal degeneration

      2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
    Type 1 Excludes
    Corneal degeneration
Clinical Information
  • A corneal disease in which there is a deposition of phospholipid and cholesterol in the corneal stroma and anterior sclera.
  • Degenerative changes of the cornea related to aging that are highly influenced by changes in the corneal endothelium. Changes include corneal topography, increased density, decreased hydration of the corneal stroma, and epithelial basement membrane dystrophy; the stroma appears hazier than in younger eyes and reduces light transmission. Changes may also include age-related stromal degeneration and deposition.
