The VDP website includes news, information, and resources needed for pharmacy participation in Texas Medicaid. All content is free, and no account is necessary to access services. We encourage all pharmacy staff to provide the proper education and instruction so your staff may take full advantage of these resources.


The Office of the Ombudsman helps when a program's normal complaint process cannot or does not satisfactorily resolve the issue. You can submit your request online.
