1What Is the A043 OHIP Code?
The A043 code is employed for specific assessments in the field of neurosurgery. It is designed for cases where a detailed examination of the patient's presenting complaint and relevant systems is required, focusing on specific neurological symptoms or issues.
In clinical practice, this is commonly used when a patient presents with specific issues such as radicular leg pain, where the neurosurgeon needs to assess for potential neurological deficits and correlate these with imaging studies to determine if surgical decompression or another intervention is necessary.
This code is frequently missed when the focus is too broad, or if the documentation does not clearly delineate a thorough and detailed assessment of the specific issue, required by the OHIP guidelines for this billing code.

| Code | Name | Frequency | Description |

| C044 | Specific re-assessment | Frequency varies by patient needs | Follow-up assessment in neurosurgery. |
| A044 | Partial assessment | Frequency varies by patient needs | Assessment covering part of the problem. |
| A935 | Special surgical consultation | As needed | Comprehensive consultation for surgical planning. |
3Eligibility Requirements
The A043 code is eligible for billing under OHIP when the neurosurgeon performs a specific assessment that includes a full history of the presenting complaint, along with a detailed physical examination of the affected systems. It must be rendered in a clinical setting, excluding the patient's home.
Frequency limits dictate that a specific assessment can be billed once per patient per physician within a 12-month period. However, if the patient returns with a clearly different and unrelated diagnosis, or if at least 90 days have elapsed and the second assessment is a hospital admission assessment, the assessment limit increases to two per patient per 12-month period.
Physicians must document the start and end times of the assessment to ensure eligibility for billing. Virtual delivery of the assessment is permitted and billed under A043A.
4What Your Clinical Note Must Show
Ensure the service start and end times are recorded in the patient's medical record or chart for billing purposes.
- Log precise timing
- Include date of service
Document a full history and detailed examination related to the presenting complaint.
- Presenting complaint history
- Detailed examination of affected systems
- Indications for further intervention
For virtual assessments, ensure the billing code A043A is used.
- Document platform used
- Patient consent for virtual care
5Weak vs. Strong Note Examples
The strong note provides a detailed history, links examination findings with imaging, and outlines a clear plan, meeting the requirements for a specific assessment. The weak note lacks detail and does not adequately document examination or correlate findings necessary for A043 billing.
Patient presents with leg pain. Reviewed MRI. Considered surgery.
Patient presents with right leg radicular pain. Detailed examination revealed diminished reflexes in the right S1 distribution. MRI shows L5-S1 disc herniation correlating with symptoms. Plan: Consider L5-S1 decompression.
- Full history of radicular pain including onset, duration, and previous treatments
- Specific neurological examination findings
- Correlate imaging results with clinical findings
- Consideration for surgical intervention documented
