1What Is the A615 OHIP Code?

The A615 billing code is used for hematology consultations in Ontario, Canada. It applies to assessments carried out by a hematologist following a referral from a physician, nurse practitioner, or dental surgeon. These consultations are typically requested for complex or obscure cases relating to unexplained blood disorders such as an abnormal blood count or thrombophilia.

Physicians frequently overlook the requirements of maintaining documentation of the referral source and the specific medical query that led to the consultation. This oversight can result in reduced fees as per OHIP guidelines. It’s essential to understand the context and maintain accurate documentation to avoid billing complications.

3Eligibility Requirements

A615 consultation services require a written request from a referring physician, nurse practitioner, or dental surgeon. This documentation must include the consultant's identification, the referrer's details, and patient information. The consultation should address a complexity necessitating specialized input.

Frequency limits dictate that consultations for the same diagnosis, same patient, and same physician are allowable once per two consecutive 12-month periods, with exceptions applying under certain hospital or emergency department scenarios. Related but clearly different diagnoses may warrant a separate consultation within a 12-month cycle.

Virtual consultations must be conducted via video; telephone consultations for A615 are not permissible.
