Wi medicaid denials

We had a husband and wife come in on the same day for preventive visits. Each had flu shots and labs done. WI Medicaid is denying the 90471 for both, the flu vaccine codes used were 90656 and 90658. Also denied was the venipuncture code 36415 when coded with 85025 (CBC). Does WI Medicaid follow Medicare guidelines for venipuncture codes and reimbursement as well as bundling the administrative code for flu vaccinations into one reimbursement fee?

Any insight will be helpful,
