1What Is the W166 OHIP Code?
Repeat consultations under the W166 billing code are additional consults rendered by the same nephrologist for the same presenting kidney-related problem, after another physician has managed the patient in the interim. They are crucial for managing chronic kidney disease in non-emergency long-term care in-patient settings such as chronic care hospitals, nursing homes, and homes for the aged.
Typical scenarios include revisiting a patient's treatment plan after a decline in kidney function managed first by a facility physician. These consultations ensure continuity and specialization in patient care, responding to complexities unique to nephrology.
W166 often gets overlooked when practitioners do not obtain a new written referral, a requirement that differentiates it from standard assessments. Ensure these repeat consultations are flagged correctly to capture full reimbursement.

3Eligibility Requirements
Eligibility for billing W166 requires the following:
- Setting: The consultation must take place in a non-emergency long-term care in-patient environment, such as chronic care hospitals, nursing homes, or homes for the aged, but excluding palliative care beds.
- Consultation Requirements: A new written request from a referring physician, nurse practitioner, or dental surgeon must be available. This can be an external document or part of a shared medical record system in a hospital or multi-specialty clinic.
- Service Eligibility: Repeat consultations should follow care rendered to the patient by another healthcare provider, focused on the same diagnosis, and outside the limitations provided by OHIP's synthetic two consecutive 12-month period rule, which exempts W166 from counting towards those limits.
4What Your Clinical Note Must Show
Ensure a written consultation request is included in the patient's medical records.
- Request must be signed by referring provider.
- Kept directly or within shared medical record systems.
Maintain detailed consultation notes that reflect the ongoing care needs of the patient.
- Diagnosis and treatment plan updates.
- Communication of changes or recommendations to the referring physician.
5Weak vs. Strong Note Examples
The strong note provides detailed clinical insight and attaches necessary referral documentation, supporting the billing claim, unlike the weak note.
