VA Request for Information regarding EVV

The U.S. Department of Veterans Affairs is exploring using Electronic Visit Verification (EVV) for providing homemaker/home health services.  EVV is currently mandated to record delivery of Medicaid services. This is only a preliminary study by VA. Please provide thoughtful answers to the below questions.
1.If your agency participates in Medicaid Waiver home care, how would you describe your experience with the EVV vendor?
2.Which EVV vendor does your state use?
3.If the VA required EVV for your veteran clients that receive homemaker/home health care, what recommendations/advice could your provide to VA on how to implement that?
