1What Is the A233 OHIP Code?
What is the A233 OHIP Billing Code?
The A233 billing code is a specific assessment fee under the Ontario Health Insurance Plan (OHIP), primarily used by ophthalmologists. This focused assessment involves a complete history of the presenting complaint and a detailed examination of the affected part(s) or system(s) to diagnose or rule out disease and assess function.
Clinically, this code is used for issues like a red eye, new field defect, or post-operative complication, rather than conducting a comprehensive eye examination. It allows ophthalmologists to deliver targeted care tailored to the patient's specific complaint.
This code can be easily missed if not thoroughly documenting both the detailed history and physical examination required. It's crucial for practitioners to ensure that they meet the specific criteria to avoid rejection in claims processing.

3Eligibility Requirements
Eligibility Requirements
According to OHIP guidelines, specific assessments are limited to one per patient per physician per 12-month period. However, you can bill for a second specific assessment if one of the following conditions is met:
- The patient presents a second time with a complaint that results in a different, unrelated diagnosis within the same 12-month period.
- At least 90 days have elapsed since the last specific assessment and the second assessment occurs at a hospital admission.
Remember that the assessment must be performed by a specialist in a location other than the patient's home. A thorough history, examination, and documentation in the permanent medical record, including start and end times, are mandatory.
4What Your Clinical Note Must Show
Ensure accurate logging of service time and thorough documentation.
- Record the start and end times of the service in the patient's medical record.
- Include a full history of the patient's presenting complaint.
- Conduct a detailed examination of the affected parts or systems.
