1What Is the W445 OHIP Code?

W445 is a billing code used in Ontario's OHIP system to claim reimbursement for consultations in medical oncology for long-term care in-patients. This service is typically provided in a nursing home or homes for the aged, where patients often present with new or progressing malignancies. A consultation under this code focuses on determining the appropriateness of systemic therapy given the patient's frailty and overall goals of care.

Physicians might miss billing this code correctly if subsequent visits are inappropriately billed as additional consultations instead of follow-up visits. It is crucial to distinguish between a first-time consultation and subsequent evaluations for management consistency and accurate billing.

3Eligibility Requirements

To be eligible to bill W445, the consultation must be provided by the same physician for the same patient and diagnosis only once every two consecutive 12-month periods. However, it can be billed twice within this period if the second consultation occurs for a hospital inpatient or emergency department patient between 12 to 24 months after the first service.

A consultation for an unrelated diagnosis can be billed every 12 months. Additionally, the service may be claimed no less than six months after a periodic health visit as specified by the Nursing Homes Act. Services above these frequencies are reimbursed at the general or specific assessment rates.
