What is EVV?
Electronic visit verification (EVV) is federally mandated for certain in-home services through the 21st Century Cures Act to reduce Medicaid fraud.
EVV uses GPS location tagging when a caregiver clocks in and out at a member’s home to verify a member has received services.
How does it work?
North Carolina Tailored Plans (and most Standard Plans) have partnered with HHAeXchange (HHA) as their designated EVV vendor.
EVV mandated services must have visit verification attached to claims.
Caregivers must clock in and out through HHAeXchange approved methods including the free HHAeXchange app (for all smartphones) or telephonic clocking via member’s home land-line.
What services are mandated?
For select services under the Innovations Waiver, 1915i and TBI (Traumatic Brain Injury) Waiver and in-home personal care service (PCS), EVV must be captured and invoiced (billed and exported) from HHAeXchange.
For a complete list of EVV-mandated services under these programs, please see our EVV Service Matrix and Crosswalk.
For select home health services, providers must capture visits (caregiver clock in and out), but have the option to bill through HHAeXchange, or bill the claims directly to Alliance.
Please review Alliance’s Home Health Crosswalk for information on what services are mandated, and how authorizations should be obtained to bill select non-covered service codes.
HHAeXchange
If you will need to bill for or capture EVV visits and have not yet signed up to use HHA through their free MCO portal, please do so through the HHAeXchange LME Provider Portal Questionnaire.

How to bill when issued an “ALL” authorization.
Alliance utilizes an “ALL” authorization for CLS under Innovations and 1915i waivers to allow a provider to bill for EVV (In-home) services as well as the community equivalent (when a visit begins or ends in the community) without having to issue multiple authorizations.
Reference our EVV Service Matrix to see how CLS crosswalks into its community and EVV-exempt equivalents.
This can cause some confusion when billing through HHAeXchange, so they have provided the below linked PDF to assist you in billing against an “ALL” authorization:
