1What Is the A160 OHIP Code?

A160, the Comprehensive Nephrology Consultation, is a specific OHIP billing code for nephrologists who provide an extensive consultation service requiring at least 75 minutes of direct patient contact. This service includes a detailed assessment and discussion with patients suffering from complex kidney issues such as advanced chronic kidney disease. Key elements often covered in this consultation include treatment modality choices, vascular access planning, and medication reviews.

This code typically applies to situations where the nephrologist's expertise in managing intricate renal cases is essential. Billing the A160 code accurately ensures that the physician is compensated appropriately for the time and expertise involved.

Physicians may miss using this code if they do not meet the minimum time requirement or if comprehensive documentation is not maintained. It's important to ensure all consultation elements, including written requests and reports, are carefully documented.
