1What Is the K737 OHIP Code?

What is K737?

K737 is a billing code used by consultant physicians participating in CritiCall telephone consultations, chiefly while on duty in an emergency department or urgent care clinic. This service involves discussing patient management and the potential transfer of critically ill patients.

Such calls are distinct because they require coordination for patient stabilization and transfer feasibility. Consultants may bill K737 in these scenarios instead of using K733, which applies to office settings. It's important to distinguish between these to ensure accurate billing.

6Common Reasons This Code Is Missed

1
Incorrect Setting
K737 may be missed if billed outside of the emergency department or urgent care setting.
2
Misidentification with K733
Confusing the CritiCall phone consultation with office settings may lead to incorrect billing with K733 instead of K737.
3
Inadequate Documentation
Failing to document the critical elements of the consultation, such as the transfer discussion or data review, may lead to denial.
4
Exceeding Frequency Limits
Billing more than the allowed number of services per patient or provider per day could lead to non-payment.
