The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on corneal implants for keratoconus.

  • Description

    Keratoconus is a disease of the cornea which affects the shape of the eyeball and causes refractive errors, some of which cannot be corrected by spectacles or contact lenses. The insertion of clear plastic implants into the cornea is an interventional procedure aiming to restore eyesight in patients with this condition.

  • OPCS4.6 Code(s)

    C46.4 Insertion of prosthesis into cornea

    Excludes: Insertion of therapeutic contact lens (C51.5)

    In addition ICD-10 code H18.6 Keratoconus or Q13.4 Other congenital corneal malformations or a combination of Dagger(†) and Asterisk(*) codes Q90.-† Down’s syndrome and H19.8A Other disorders of sclera and cornea in diseases classified elsewhere would be assigned. In the ICD-10 4th Edition † and * codes must appear together, sequencing depends on which is the main condition treated or investigated during the consultant episode, if this is not clear the † code is assigned before the * code.

    The NHS Classifications Service of NHS Connecting for Health is the central definitive source for clinical coding guidance and determines the coding standards associated with the classifications (OPCS-4 and ICD-10) to be used across the NHS.   The NHS Classifications Service and NICE work collaboratively to ensure the most appropriate classification codes are provided.
