Electronic Visit Verification Provider Choice Systems Information

Welcome Provider Choice Users!

The 21st Century CURES Act, passed in December 2016, requires state Medicaid programs to implement an Electronic Visit Verification (EVV) system for Personal Care and Home Health services. Per section 12006, all states must implement an EVV system to avoid a reduction in federal Medicaid funding. EVV is an electronic-based system that verifies when provider visits occur and documents the precise time services begin and end, ensuring that members receive authorized services. To be in federal compliance, all EVV systems must collect the six points of data listed below.

  1. Type of service performed
  2. Individual receiving the service
  3. Date of the service
  4. Location of service delivery
  5. Individual providing the service
  6. Time the service begins and ends

On late summer 2020, the Department of Health Care Policy & Financing (the Department) will require Health First Colorado (Colorado's Medicaid Program) providers of EVV mandated home and community-based and state plan services to use EVV. Colorado is implementing EVV for federally required services and additional services that are similar in nature and service delivery. A list of services that require EVV in Colorado is listed below.

Participation in the EVV is mandatory for the following programs and services. Provider agencies not in compliance with EVV by late summer 2020 may experience a disruption in reimbursement.

Colorado Implementation

The Colorado EVV program has deployed a hybrid model. A hybrid model means that a provider agency may choose to use the State EVV Solution at no cost or an utilize an alternate EVV vendor. Providers who choose to utilize an alternate EVV solution must ensure that their system is configured to Colorado EVV rules and requirements. A list of vendors who have interfaced with Sandata in other states is available. Interface time may be reduced by choosing a vendor from this list. The Department does NOT endorse any vendor or recommend using a vendor from this list.

The Department strongly recommends that providers decide if they will utilize an alternate EVV vendor to ensure adequate time for interface testing. It is each provider's responsibility to have a functional EVV solution by late summer 2020.
