1What Is the W460 OHIP Code?
W460 is an OHIP billing code used for comprehensive infectious disease consultations with a minimum direct contact time of 75 minutes. Exclusively applicable to in-patients within chronic care facilities, this service addresses complex scenarios such as chronic wound infections or recurrent institutional outbreaks among long-stay residents.
This code is frequently utilized for patients in settings like chronic care hospitals, nursing homes, and homes for the aged. Due to its specific direct patient interaction requirement, it's essential that the physician allocates dedicated time solely for this consultation, ensuring all elements of a full consultation are satisfied as per OHIP guidelines.

3Eligibility Requirements
W460 can be billed under the following conditions:
- The consultation must be rendered by a specialist in infectious disease.
- The consultation involves at least 75 minutes of direct contact with the patient, excluding any other separately billable intervention.
- Services in excess of allowed frequency limits are adjusted to a lesser-paying fee.
Consultations rendered by the same physician for the same patient and diagnosis are restricted to one per two consecutive 12-month periods. However, two services are permissible if the second is for a hospital inpatient or an emergency department patient between 12 and 24 months after the first. Consultations for unrelated diagnoses may be billed once every 12 months.
4What Your Clinical Note Must Show
The start and stop times of the consultation must be recorded in the patient's permanent medical record.
- Ensure all direct contact is documented separately from non-patient-facing time.
- Inaccurate time documentation results in fee adjustments.
All elements of a standard consultation must be included.
- Consultation must follow a written referral from a qualified healthcare provider.
- Written report of findings and recommendations must be provided to the referring physician.
5Weak vs. Strong Note Examples
The strong note provides a clear timeline for consultation duration and detailed aspects of the assessment, satisfying OHIP documentation requirements, whereas the weak note lacks specifics and comprehensive documentation.
