1What Is the A355 OHIP Code?

What is A355?

The A355 code is used for billing consultations performed by urologists under the Ontario Health Insurance Plan (OHIP). This service involves a detailed evaluation of complex patient cases such as haematuria, elevated PSA, obstructive symptoms, or scrotal masses. A355 provides the framework for a comprehensive assessment, which includes collaborating with a referring physician, nurse practitioner, or dental surgeon.

Often missed due to documentation oversights, it's essential to ensure that all referral and consultation documentation is correctly completed and maintained. The complex nature of cases within urology highlights the importance of these consultations, contributing valuable insights for patient management.

3Eligibility Requirements

Eligibility Requirements

To bill the A355 code, a consultation must meet specific criteria:

  • Request: The consultation must follow a written request from a referring physician, nurse practitioner, or dental surgeon. This request must be based on the complexity or seriousness of the patient's condition, requiring the specialized opinion of a urologist.
  • Consultation Report: A comprehensive consultation report, including findings, opinions, and recommendations, must be prepared and sent to the referring provider.
  • Documentation: Maintain a copy of the written referral request in your medical records, except when common records are used, in settings like hospitals or multi-specialty clinics.
  • Frequency Limits: Typically, one A355 service per patient, per physician, per diagnosis, over two consecutive 12-month periods, with exceptions for hospital inpatients and emergency care.
  • Virtual Services: A355 can be billed as A355A if the service is rendered via video, not telephone.

Failure to meet these requirements will result in the service being paid at a lesser assessment fee.
