1What Is the C043 OHIP Code?
The C043 OHIP billing code applies to specific assessments conducted by neurosurgeons within a hospital inpatient setting. This code should be utilized when a detailed evaluation is necessary to assess a specific neurosurgical concern, such as evaluating a minor traumatic hemorrhage or assessing a new neurological deficit in patients with existing spinal disease.
Such assessments require the neurosurgeon to take a comprehensive history of the presenting complaint and to perform a detailed examination of the affected region or system. This ensures a thorough diagnosis, exclusion of potential diseases, or assessment of neurological function.
Physicians often overlook using C043 due to misunderstanding eligibility criteria or failure to document the necessary details required by OHIP, leading to incorrect billing and potential revenue losses.

3Eligibility Requirements
To bill using C043, the service must be provided in a non-emergency hospital inpatient setting. The specific assessment is inherently distinct from assessments done at a patient's home and must involve a thorough history and examination of the patient's condition. The billing is limited to one assessment per patient per physician within a 12-month period unless a second distinct and unrelated diagnosis arises. Alternatively, a second assessment is allowable if it is a hospital admission assessment and at least 90 days have elapsed since the previous assessment.
Ensure time is accurately recorded in the patient's medical record to verify the start and end of the service. Virtual assessments under C043 can also be conducted but must be conducted via video, not telephone, to qualify.
4What Your Clinical Note Must Show
Document the precise time in the patient's medical record for service delivery.
- Record the start and end times of the assessment.
- Ensure accurate documentation to validate service for OHIP.
Comprehensive documentation of the patient’s presenting condition and assessment process.
- Complete medical history of the presenting complaint.
- Thorough examination details of the affected parts or systems.
5Weak vs. Strong Note Examples
The strong note succeeds because it provides a complete clinical picture and justifies the need for the assessment, whereas the weak note lacks detail and fails to convey the complexity of the condition assessed.
Patient presented with a headache. Examined briefly and advised rest.
Patient presented with a severe headache and dizziness. Obtained a detailed history indicating recent head trauma. Conducted a comprehensive neurological examination, focused on possible intracranial hemorrhage.
- Documented all examination findings, including neurological function.
- Discussed potential need for further imaging based on exam findings.
