1What Is the C911 OHIP Code?

C911 is an OHIP billing code used for special consultations conducted by family physicians for hospital inpatients. These consultations involve at least 50 minutes of direct patient contact to address complex cases that require comprehensive evaluation, often involving multiple chronic issues.

This code is typically utilized when the hospital ward team requires an in-depth consultation that extends beyond a focused opinion. For example, a patient experiencing functional decline due to interacting cardiac, cognitive, and medication factors may necessitate such in-depth review.

Missing the opportunity to bill under C911 may occur if the consultation details, such as time spent or the consulting nature of the visit, are not adequately documented, or if requirements like the written request are not met.

3Eligibility Requirements

C911 is to be used for consultations conducted by family physicians under the following criteria:

  • The consultation involves a minimum of 50 minutes of direct patient contact.
  • The service must follow a written request from a referring provider, which can be a physician, nurse practitioner, or dental surgeon, highlighting the complexity or obscurity of the case.
  • Documentation including start and stop times must be recorded in the patient's medical record.
  • The consultation is typically limited to one service per two consecutive 12-month periods for the same patient and diagnosis, with specific exceptions allowing for a second service in certain inpatient or emergency settings.
  • Consultations for a clearly defined unrelated diagnosis are eligible for billing once every 12 months.
  • Services exceeding these frequencies may be adjusted to a lesser fee.

Weak Note

Strong Note
