As a company, can't I adjudicate my own Health Spending Account claims?

No. Under CRA guidelines it is essential that an independent 3rd party service is used to adjudicate Health Spending Account claims. The 3rd party must be thoroughly trained and follow CRA guidelines.

Further, the 3rd party adjudication service must maintain strict privacy in the processing and viewing of the claim information for employees of a company. It would violate health privacy legislation if an employer were allowed to view the medical information of one of its employees.
