A237 – 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 A237 for a child aged 19 or younger presenting for a routine eye check to screen for myopia, hypermetropia, or astigmatism, provided it's been at least 12 months since their last periodic oculo-visual assessment (A237 or A239).
- Use A237 when the primary purpose of the visit is to assess for a simple refractive error in a patient under 20, even if a minor abnormality is found during the examination.
- A237 is appropriate for a patient aged 19 or younger requiring a comprehensive eye exam including visual acuity, slit lamp, and ophthalmoscopy, distinct from a problem-focused visit.
Common Pitfalls
- Billing A237 more than once within a 12-month period for the same patient, even if the previous assessment was by an optometrist.
- Submitting A237 for a patient aged 20 or older; these patients require a different assessment code, such as A115.
- Billing A237 on the same day as another insured service by the same physician, unless it is an eligible add-on code like A230.
Billing Tips
- Ensure all required components of the assessment (history, visual acuity, slit lamp, ophthalmoscopy, tonometry) are documented to support the A237 claim.
- If a patient requires an orthoptic assessment (A230) during the same visit as A237, bill A230 as an add-on code to A237.
