1What Is the C160 OHIP Code?

The C160 billing code is used for a comprehensive nephrology consultation in a non-emergency, hospital in-patient setting. This involves 75 minutes of direct contact with the patient, aiming to assess complex cases such as acute kidney injury with chronic disease backgrounds. These consultations may involve considering dialysis initiation, which justifies the comprehensive nature of the evaluation.

This code ensures nephrologists provide thorough evaluations and tailored recommendations, meeting specific patient needs within a hospital setting. Misunderstanding eligibility, such as consultation duration requirements or appropriate diagnosis, can lead to billing errors.

3Eligibility Requirements

The C160 code is available for specialists in nephrology providing consultations in a hospital in-patient setting. To be eligible, the consultation must:

  • Be initiated by a written request from a referring physician, nurse practitioner, or dental surgeon.
  • Involve a minimum of 75 minutes direct contact with the patient.
  • Occur every two consecutive 12-month periods per patient/physician/diagnosis, with two services allowed if one consultation occurs 12 to 24 months after the first for in-patients or Emergency Department cases.
  • For unrelated diagnoses, one consultation is allowed every 12 months.

Ensure compliance with these conditions to avoid claim adjustments.
