A110 – Periodic oculo-visual assessment - aged 19 years and below
OHIP General Listings Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A periodic oculo-visual assessment is an examination of the eye and vision system rendered primarily to determine if a patient has a simple refractive error (defined as myopia, hypermetropia, presbyopia, anisometropia or astigmatism) for patients aged 19 or less.
When to Use
- Bill A110 for a child aged 10 presenting for their first comprehensive eye exam to check for myopia or astigmatism.
- Use A110 for a 17-year-old who has not had a periodic oculo-visual assessment in the past 12 months and requires a refraction check.
- A110 is appropriate for a 5-year-old with a family history of strabismus, undergoing a routine visual assessment including motility testing.
Common Pitfalls
- Billing A110 for a patient aged 20 or older; these patients require A115.
- Submitting A110 more than once within a 12-month period for the same patient, even if the assessment was performed by different physicians or an optometrist.
- Billing A110 on the same day as another insured service by the same physician (excluding ophthalmologists); use a different assessment code if necessary and appropriate.
Billing Tips
- Ensure all required components, including history, visual acuity, slit lamp exam, ophthalmoscopy, and tonometry, are documented to support the A110 claim.
- If a patient requires a re-assessment after an A110, bill a lesser assessment code (e.g., A007) with diagnostic code 367, not another A110.
