1What Is the W175 OHIP Code?

What is W175?

W175 is an OHIP billing code specifically used for consultations by vascular surgeons in non-emergency long-term care settings. This includes chronic care hospitals, nursing homes, and homes for the aged. The code reflects the complexity and specialized nature of consultations typically required in assessing non-healing arterial or venous ulcers, or when determining ongoing care such as revascularization for frail, long-term residents. Despite its straightforward nature, the code can often be missed if eligibility and documentation requirements are not strictly followed.

3Eligibility Requirements

Eligibility

W175 is applicable only to non-emergency, long-term care in-patient services provided by vascular surgeons. Eligibility requires that the consultation occurs in chronic care hospitals, convalescent hospitals, nursing homes, homes for the aged, or designated chronic/convalescent care beds, excluding palliative care beds. Consultations cannot be self-referred and must follow a written request from a referring physician, nurse practitioner, or dental surgeon. Services exceeding frequency limits may result in payment at a lower assessment rate.
