Bill dates of service correctly to boost accuracy of claims processing

Blue Cross Blue Shield of Michigan frequently receives medical claims with an incorrect date of service. To help ensure that the correct dates are used, we want to let you know that Blue Cross defines “date of service” as the actual date the service was rendered to the patient.
For example, the date of service is the date when a patient receives an X-ray or the date a lab or pathology sample is taken.
Even when the tests are analyzed on a different day, use the date of service as it’s described in this article to bill the charge. Following this direction will help us process your claims with greater accuracy.
