What is A461?
The A461 OHIP billing code is used by infectious disease specialists in Ontario, Canada, for complex medical specific re-assessments. This code is typically applied in cases where the patient's condition is particularly severe, complex, or obscure, necessitating a detailed follow-up assessment.
Such assessments are commonly used in outpatient clinics for evaluating patients undergoing long courses of antimicrobial therapy. Due to the intricate nature of conditions treated in infectious disease, these reassessments play a crucial role in ensuring effective management and treatment adjustments based on a patient's ongoing response to therapy.

3Eligibility Requirements
Eligibility Requirements
For billing under A461:
- Physicians must include all elements of a medical specific assessment. If not, adjustments will be made to a lower paying assessment fee.
- Complex infectious disease assessments are capped at six per patient per physician within a 12-month period. Any services exceeding this limit will also be adjusted to a lesser assessment fee.
- Physicians must record start and stop times of the assessment in the patient's permanent medical record. Without this documentation, the billed service will not be reimbursed at the complex assessment rate.
- A maximum of four complex medical specific re-assessments per patient per physician per 12 months are reimbursed.
4What Your Clinical Note Must Show
Physicians must ensure proper documentation to meet OHIP billing standards:
- Clearly record start and stop times in the patient's medical record.
- Ensure all elements of a medical specific assessment are included.
- Maintain detailed patient records reflecting the complexity and reason for reassessment.
5Weak vs. Strong Note Examples
The strong note provides detailed clinical rationale and includes required start and stop times, justifying the complex reassessment. The weak note fails to document necessary details, potentially leading to billing issues.
