1What Is the A084 OHIP Code?

A partial assessment, billed under OHIP code A084, is a limited type of patient evaluation undertaken by plastic surgeons. It involves documenting a brief history of the presenting complaint, performing a necessary physical examination, and offering appropriate advice to the patient. Clinically, this type of assessment is often used during follow-up visits to inspect healing wounds or to ensure the proper application of dressings.

Despite its straightforward nature, partial assessments can be frequently overlooked due to the assumption they're less significant or because comprehensive assessments seemed more appropriate. It's important for practitioners to recognize scenarios where a limited review is adequately reflective of the service rendered to avoid potential billing discrepancies.
