How do I find out which EVV vendor my state uses?

Use the table on this page to look up your state. State EVV vendor assignments change occasionally; always confirm with your state Medicaid agency's current EVV bulletin before signing any contract or building any integration. Closed-model states (Sandata-PA, HHAeXchange-NY, Tellus-FL, others) require the state-contracted aggregator. Open-model states let you pick from approved vendors that export to a centralized aggregator.

Can my home care software work with any state's EVV vendor?

Most modern home care platforms (AveeCare, AxisCare, AlayaCare, WellSky Personal Care, KanTime, CareSmartz360) export EVV data to all major state aggregators. The export format is standardized to the CMS 7-data-element specification. The differences live in implementation: how cleanly the export reconciles, how visit-maintenance corrections flow back, and whether the vendor stays current on state aggregator API changes.

What happens when a state changes its EVV vendor?

State Medicaid agencies re-bid EVV contracts every 5-10 years. When a contract changes (e.g. Sandata to HHAeXchange), agencies operating in that state need to: (1) re-credential with the new aggregator portal, (2) re-train staff on the new portal, (3) confirm the EHR vendor has tested its export against the new aggregator, (4) reconcile data during the transition period. Plan a 60-90 day transition window when a state announces a vendor change.

Does AveeCare's EVV export work in all 50 states?

Yes. AveeCare exports EVV data to all 50 state aggregators at $6 per active client per month, with no separate per-state or per-visit fee. We monitor state aggregator API changes and roll updates as they ship; you do not need to manage state-by-state integrations yourself.
