This guidance, clarifying the use of these supplementary reason codes, was produced in consultation with the Scottish Government Health Directorates and Optometry Scotland.

If you carry out a supplementary eye examination on the same day as a primary eye examination, full details of the reasons why must be provided in the patient’s records. You must enter the relevant reason code on your claim.

For the purposes of NHS primary and supplementary eye examinations, a "sight test" means a refraction.

Claims dated after 1 August 2025

Standard Supplementary Eye Examination (Post Aug 2025)

3.0 Additional or Significantly Longer Appointment To Complete Primary Eye Examination For A Patient With Complex Needs

This code can be used for an additional appointment (whether or not on the same day as the first appointment), or a significantly longer single appointment, required to complete a primary eye examination in practice premises for a patient with complex needs, when more time to complete the examination is needed. This code should be claimed in addition to the relevant primary eye examination fee. This code must not be used more than once per day for the same patient. A patient with complex needs is a patient who has a physical or mental condition and, as a result of that condition, the patient’s primary eye examination must be conducted significantly more slowly than that of a typical patient who does not have a physical or mental condition. This includes circumstances where a sign-language interpreter is required because of the patient’s physical or mental condition. A patient must not be treated as having complex needs solely due to their age.

3.1 - Paediatric Review (without dilation/cycloplegia that does not follow a primary eye examination)

This code is to be used to review a child within 12 months of a primary eye examination, as judged clinically necessary, and dilation/cycloplegia is not required.

3.2 - Follow-Up / Repeat Procedures (without dilation and not associated with glaucoma)

This code is to be used for additional or repeat procedures not requiring dilation and which are required to refine a diagnosis or clinical outcome in order to determine whether the patient needs referral or can be retained for ongoing care in the community. This code can be used for a refraction, on a separate day, that could not be undertaken at the primary eye examination.

3.3 - Suspect Glaucoma (without dilation)

This code is to be used specifically for suspect glaucoma review, in keeping with SIGN 144 guidance for diagnosis and referral for glaucoma, and which does not require dilation. This includes ocular hypertension.

3.5 - Anterior Eye Condition (without dilation)

This code is to be used for a supplementary eye examination of a patient (in person or using remote facilities) with a suspect or diagnosed anterior eye condition within the normal interval between primary eye examinations, and which does not require dilation.

3.7 - Post-Operative Cataract Examination (without dilation)

This code is to be used for a post-operative cataract examination of a patient, which includes refraction, an ocular examination and (if required) a feedback report, but does not require dilation. This code should not be used for a post-operative cataract examination of a patient where a GOS provider has, is or will receive remuneration outwith GOS arrangements for undertaking the appointment. Such examinations do not form part of GOS.

3.8 - Unscheduled Appointment (without dilation)

This code is to be used for a supplementary eye examination for a patient (in person or using remote facilities) who presents with symptoms for an unscheduled appointment within the normal interval between primary eye examinations, and which does not require dilation.

3.9 - Cataract Referral Advice and Counselling

This code is to be used when providing advice and counselling to a patient (in person or using remote facilities) following an eye examination which has resulted in the patient being considered for referral. This may include providing prognosis or counselling and preparation for consent for cataract surgery, including risk factors.

Enhanced supplementary eye examination codes (Post Aug 2025)

Conduct an enhanced supplementary eye examination when you deem it clinically appropriate to support the care of the patient.

4.1 - Paediatric review (with dilation/cycloplegia that doesn't follow a primary eye examination)

Use this code when you review a child within 12 months of a primary eye examination, as judged clinically necessary, and dilation/cycloplegia is required.

4.2 - Follow-up / repeat procedures (with dilation and not associated with glaucoma)

Use this code for any additional or repeat procedures requiring dilation that are required to refine a diagnosis or clinical outcome. The result will determine whether the patient needs referral or can be retained for ongoing care in the community.

4.3 - Suspect glaucoma (with dilation)

Use this code specifically for a suspect glaucoma review, in keeping with SIGN 144 guidance for diagnosis and referral for glaucoma, and which requires dilation. This includes ocular hypertension.

4.5 - Anterior eye condition (with dilation)

Use this code for a supplementary eye examination of a patient with a suspect or diagnosed anterior eye condition within the normal interval between primary eye examinations. Dilation will occur.

4.6 - Cycloplegic refraction of a child referred from the hospital eye service

Use this code when facilitating the cycloplegic refraction of a child aged under 16 referred from the hospital eye service. The supplementary eye examination must include an internal and external examination of the eye.

4.7 - Post-operative cataract examination (with dilation)

Use this code for a post-operative cataract examination of a patient, which includes refraction, an ocular examination and (if required) a feedback report, and also requires dilation.

4.8 - Unscheduled appointment (with dilation)

Use this code for a supplementary eye examination for a patient who presents with symptoms for an unscheduled visit within the normal interval between primary eye examinations. Dilation will be required.

Specialist Supplementary reason codes (Post Aug 2025)

5.0 – First Specialist Supplementary Eye Examination Appointment

This code is to be used for the first specialist supplementary eye examination of a patient who receives any Stage 2 treatment as specified in PCA(O)2025(04), Annex C. An episode of care at Stage 2 is defined as being complete when the condition:

• has been resolved successfully;
• does not respond to treatment or does not resolve, and onward referral is made for medical support/intervention; or
• steps down to Stage 1 on the Treatment Ladder

Where an episode of care is complete and no follow-up appointments with the patient are scheduled, and the anterior eye condition later reoccurs such that the IP optometrist or OMP determines that the provision of any Stage 2 treatment is clinically required in accordance with Annex C, then a new episode of care is deemed to have commenced and a GOS claim under this reason code can be made.

5.1 – Second Or Subsequent Specialist Supplementary Eye Examination Appointment

This code is to be used in the following circumstances:

• for the second and subsequent specialist supplementary eye examination of a patient who receives any Stage 2 treatment as specified in Annex C. This would normally be with the same IP optometrist or OMP but might be with another IP optometrist or OMP where the original IP optometrist or OMP is no longer able to manage the patient (for example due to unexpected absence);
• where the patient is confirmed to have an anterior eye condition set out in Annex C, is deemed to require more complex treatment than Stage 2 as specified in Annex C, and is therefore referred onto an ophthalmic hospital or a General Practitioner

Claims dated prior to 1 August 2025

A supplementary eye examination can't be claimed on the same day as a primary eye examination for the same patient, if you're using any of the following reason codes:

• 2.1
• 2.7
• 4.1
• 4.6
• 4.7

Reason codes 2.5, 2.8, 4.5 and 4.8 should also only be claimed on the same day as a primary eye examination for the same patient, where the supplementary eye examination is an emergency.

Standard Supplementary Eye Examination (Pre-Aug 2025)

See the codes below and add them to your claim if necessary.

2.0 – Cycloplegic refraction following routine primary eye examination on a child

Use this code when a child requires a cycloplegic refraction following a routine primary eye examination.

2.2 – Follow-up / repeat procedures (without dilation and not associated with glaucoma)

Use this code for additional or repeat procedures – not requiring dilation – that are required to refine a diagnosis or clinical outcome.

This will determine whether the patient needs referral or can be retained for ongoing care in the community.

This code can also be used for a refraction on a separate day, that could not be undertaken at the primary eye examination.

2.3 – Suspect glaucoma (without dilation)

Use this code specifically for suspect glaucoma review, in keeping with SIGN 144 guidance for diagnosis and referral for glaucoma. This includes ocular hypertension. Dilation should not occur.

Use this code following a primary eye examination, for a supplementary eye examination of a patient aged under 60 that needs dilation.

2.5 – Anterior eye condition (without dilation)

Use this code for a supplementary eye examination of a patient with a suspect or diagnosed anterior eye condition within the normal interval between primary eye examinations. Dilation should not occur.

2.7 – Post-operative cataract examination (without dilation)

2.8 – Unscheduled appointment (without dilation)

Use this code for a supplementary eye examination for a patient who presents with symptoms for an unscheduled visit within the normal interval between primary eye examinations. Dilation should not occur.

2.9 – Cataract referral advice and counselling

Use this code when providing advice and counselling to a patient following an eye examination that's resulted in the patient being considered for referral.

This may include providing prognosis or counselling and preparation for consent for cataract surgery, including risk factors.

3.0 – Additional appointment to complete primary eye examination for a patient with complex needs

Only use this code when it hasn't been possible to finish a primary eye examination in the time scheduled and the patient needs a further appointment.

A patient with complex needs is a patient who has a physical or mental condition. As a result of that condition, the patient’s primary eye examination must be conducted significantly more slowly than that of a typical patient.

Avoid treating a patient as if they have complex needs solely due to their age.
