Vendor qualifications are a critical element of the Self-Determination Program. Medicaid Waiver requires that the FMS verify that all vendors have a valid business license and are qualified to provide the services they render in the program.
The best place to find the Medicaid required qualifications would be the Medicaid waiver approval (attached below).
Appendix C - Provider Specifications for Service, outlines the requirements to provide each service. Vendors must be prepared to provide Medicaid required qualifications and certifications as outlined in the waiver to the FMS to establish a vendor file and receive payment in the program.
