OHIP error code - A2A - Patient is underage or overage for this service code

Background

An A2A error represents that a service code, only eligible for patients in a specific age range, has been billed, but the patient’s age does not fall within the specified age range.

Solution

You will need to confirm if you have used the correct service code. In some cases, there are codes available for patients of a certain age, which may be allowable (even if the patient is, for example, underage), provided the patient’s diagnosis allows for the service to be billed.
