W160 OHIP Billing Code: Nephrology Consultation for Complex Cases

What is W160?

The W160 OHIP billing code represents a Comprehensive Nephrology Consultation provided to residents of chronic care facilities, such as nursing homes or homes for the aged. This consultation is typically required for patients with complex or declining renal function, where conservative management might be advised.

This consultation is distinguished by its requirement of a minimum of 75 minutes of direct patient contact. Documenting the start and stop times is crucial for eligibility. Often, physicians miss billing this code due to overlooking the necessity of recorded time or failure to meet the comprehensive consultation criteria.

Eligibility Requirements

To be eligible for billing under W160, the following conditions must be met:

• Provider: The service must be rendered by a nephrology specialist.
• Setting: Applicable to non-emergency, long-term in-patient services, such as Chronic Care Hospitals, Convalescent Hospitals, and designated chronic care beds.
• Frequency: The consultation can be billed once per two consecutive 12-month periods for the same patient, same diagnosis, except for inpatients or ER patients receiving a second consultation within 12 to 24 months. An unrelated diagnosis permits one consultation every 12 months.
• Documentation: The duration of 75 minutes of direct contact must be recorded with start and stop times in the patient’s permanent medical record.
• Referral Requirement: A written consultation request from a physician, nurse practitioner, or dental surgeon must be present and maintained in records.
