1What Is the C461 OHIP Code?
The C461 billing code is utilized for complex medical specific re-assessments by infectious disease specialists on hospital in-patients. This code is particularly relevant for cases where the patient's condition is complex, obscure, or serious, and the re-assessment provides a thorough review of the patient's state and treatment progress.
In the context of infectious diseases, typical usage involves re-evaluating an admitted patient whose infection source has not been identified, necessitating ongoing expert assessment. As these re-assessments are limited to four per patient per physician per 12-month period, it is essential to determine the necessity of this service accurately.
Failure to record the start and stop times in the patient's medical record can result in reduced payment, emphasizing the importance of thorough and precise documentation.

3Eligibility Requirements
To be eligible for the C461 billing code, the service must be provided as a non-emergency assessment of a hospital in-patient by an infectious disease specialist. The re-assessment must be necessitated by the complexity or seriousness of the patient's condition, and it must include all components of a specific medical re-assessment.
Physicians must adhere to a maximum of four complex medical specific re-assessments per patient per year, together with any medical specific assessments. The start and stop times of each assessment must be documented in the patient's permanent medical record to qualify for full payment. Additionally, C461 may also be rendered virtually through video consultation, billed as C461A, but not through telephone.
