1What Is the A285 OHIP Code?

The A285 code under OHIP represents a consultation service specifically within the specialty of pathology. It is predominantly utilized by pathologists in the office or outpatient clinic settings and involves evaluating patients for assessments such as apheresis or resolving complex laboratory findings.

This service is distinct due to its hands-on consultative nature, as opposed to mere review and reporting on specimens. The consultation acts upon a formal written request from a referring healthcare professional, emphasizing complexity, seriousness, or the need for a secondary opinion.

Frequently, these consultations are missed when practitioners fail to meet the distinct eligibility criteria, particularly those around documentation and timing of referral requests, thereby resulting in a lesser assessment fee instead.
