1What Is the C611 OHIP Code?

What is the C611 Billing Code?

The C611 code is used for billing complex medical re-assessments in the specialty of hematology. This code applies to hospital in-patient settings and is specifically utilized when patients present complex, obscure, or serious conditions that necessitate comprehensive re-evaluation. Typical scenarios include managing acute leukemia during induction, tackling disseminated intravascular coagulation, or handling complex transfusion problems.

It's important not to overlook using this billing code, especially when dealing with shifts in patients' conditions such as bleeding risks and infection threats. Accurate coding ensures appropriate compensation for the time and expertise needed in these high-stakes situations.

3Eligibility Requirements

Eligibility for C611

The C611 code is to be used in non-emergency hospital in-patient settings under the hematology category. This code requires that the re-assessment addresses the complexity, obscurity, or seriousness of the patient's medical condition. The service should be documented thoroughly, including start and end times, in the patient's medical records.

C611 can also be billed as a virtual care service, specifically through video consultations (C611A). Note that telephone consultations are not eligible under this code. Each physician can bill a maximum of four complex medical specific re-assessments per patient per 12-month period.

  • Record the exact start and end times of the service.
  • Ensure comprehensive notes detailing the complexity of the condition.
  • Document any changes in patient condition that necessitate re-assessment.

5Weak vs. Strong Note Examples

The strong note provides detailed context and specific clinical actions taken, whereas the weak note lacks the necessary detail and fails to demonstrate the complexity of the assessment.
