Prior Authorization Backdating

Initial Requests

An initial PA request may be backdated up to 14 calendar days from the first date of receipt by Wisconsin Medicaid. For backdating to be authorized, both of the following criteria must be met:

• The provider specifically requests backdating in writing on the PA request.
• The request includes clinical justification for beginning the service before PA was granted.
