1What Is the A710 OHIP Code?

Overview of A710

A710 is a billing code for comprehensive critical care medicine consultations in Ontario. This code is applicable when a critical care specialist renders a detailed consultation, dedicating a minimum of 75 minutes in direct contact with the patient. Such consultations often occur as part of an extended pre-admission or clinic assessment of patients with complex organ support needs or as a follow-up after a prolonged intensive care stay.

Comprehensive critical care consultations are critical in assessing complex health scenarios that require dedicated time and expert opinion. The service must be requested by a referring healthcare provider and documented appropriately. If not billed correctly, this lucrative service may be missed, resulting in potential loss of revenue.

3Eligibility Requirements

Eligibility Requirements for Billing A710

To bill the A710 code, the following criteria must be fulfilled:

  • Consultation Requirements: Must be a consultation resulting from a written request by a physician, nurse practitioner, or dental surgeon. This documentation must be kept in the patient's medical record unless common medical records are maintained in a hospital or clinic.
  • Time Requirement: The consultation requires a minimum of 75 minutes of direct patient contact by a critical care specialist. This time excludes any separately payable interventions and non-patient-facing time.
  • Frequency Limitations: A710 consultations are limited to one service per patient per two consecutive 12-month periods, with specific circumstances allowing for a second consultation within this timeframe.
  • Virtual Service: A710 may be provided via video under code A710A, but telephone consultations are not covered.

Adhering to these guidelines is essential for appropriate compensation under OHIP.
