Denied Requests

Once a PA request has been denied, that PA number can no longer be used. A new PA number must be used with a new request. A new request following a denial may be backdated to the original date the denied request was received by Wisconsin Medicaid when all of the following criteria are met:

• The earlier grant date is requested.
• The denied PA request is referred to in writing.
• The new PA request has information to justify approval.
• The request for reconsideration submitted with additional supporting documentation is received within 14 calendar days of the adjudication date on the original denied PA request.
