1What Is the C166 OHIP Code?
The C166 code under OHIP is used for repeat consultations in the field of nephrology within non-emergency hospital in-patient settings. This occurs when a patient, already seen by the nephrology team, experiences a recurring issue such as a second episode of acute kidney injury, or there is a change in the dialysis treatment plan.
Repeat consultations are vital in nephrology as they often follow interval care by another physician and address the same presenting problem. It is critical that these consultations arise from a written request by a referring healthcare professional.
Despite its importance, physicians might miss billing C166 due to oversight in acquiring the necessary written referral or confusion with initial or limited consultation codes.

3Eligibility Requirements
To bill for the C166 code:
- Setting: Must be rendered as a non-emergency hospital in-patient service.
- Written Request: A new written referral from a physician, nurse practitioner, or dental surgeon is mandatory. This document should be retained in the patient's medical records unless common records are maintained by the facility.
- Frequency Limitations: C166 is not subject to the same frequency limits as other consultations. Each repeat consultation is eligible for billing when accompanied by the required documentation.
- Virtual Care: C166 can be rendered virtually by video. Billing for services conducted by telephone is not covered under this code.
4What Your Clinical Note Must Show
Ensure these items are included in the medical record for a C166 billing.
- A new written request from the referring healthcare professional.
- Documentation of the patient's presenting problem and the need for a repeat consultation.
- Evidence of previous care by another physician before the repeat consultation.
5Weak vs. Strong Note Examples
The strong note provides clear evidence of a new referral, detailed clinical reasoning, and updated treatment plans, which substantiate the billing of a repeat consultation, unlike the weak note which lacks specificity.
Referred for recurrent kidney issue. Reviewed patient chart, continued current treatment.
Patient referred back for acute kidney injury recurrence.
