The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on tenotomy of horizontal eye muscles for nystagmus (with reattachment at their original insertions).

  • Description

    Nystagmus is the involuntary movement of the eyes (most commonly from side to side) and is usually associated with impaired vision. Tenotomy involves cutting the horizontal muscles of the eye (which move the eye from side to side) and reattaching them at the same place. The aim of the procedure is to improve vision.

  • OPCS4.6 Code(s)

    C34.7 Tenotomy of combinations of muscles of eye

    Z17.1 Medial rectus muscle of eye

    Z17.2 Lateral rectus muscle of eye

    Note: A code from Z94. - Laterality of operation would also be recorded to identify left, right or bilateral operation.

     This would also be recorded with the ICD-10 code H55.X Nystagmus and other irregular eye movements

    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.  www.connectingforhealth.co.uk/clinicalcoding
