Homecare AppHome care software built for Wisconsin Medicaid EVV.
Wisconsin routes EVV through Sandata (OpenEVV Alt-EVV). Homecare App captures every Medicaid visit with GPS clock-in and clock-out, coded reasons and an audit trail, and its Sandata connector is built to the published specification — the certification is completed with your agency as the sponsoring provider, at no cost to you.
Built for how Wisconsin actually receives EVV
Wisconsin agencies live inside two sets of rules: Wisconsin Department of Health Services's, and Sandata's. The software was built to both — the state's EVV requirements in the visit record, Sandata's interface in the connector — so the agency does the work once and the aggregator gets it in its own format. Open (alternate EVV) model.

One aggregator: Sandata's OpenEVV interface
Three endpoints, one order
Clients, then employees, then visits, each posted as JSON and polled to completion before the next — the appendix's own rule. The software does exactly that, and reads each record's verdict back into the visit.
Certified once per state
A vendor registers with Sandata, receives UAT credentials under a sponsoring provider in the state, passes the interface test, and is then on file for every later agency in that state.
The addendum decides the codes
Which identifier a caregiver is known by (SSN or a custom ID), which the client is, the payer and program IDs, the reason-code table and the ID formats all come from the state's addendum — and live on the account, not in code.
Wisconsin specifics
The provider files the Alternate EVV Attestation (F-02659) with Sandata; vendor certification takes up to three months (shorter if already certified in Wisconsin); DHS may require recertification; technical specification v2.6.
What Sandata wants, and where the app gets it
Every element the state names, the record it comes from in the app, and where it lands.
| Element | Where the app gets it | Where it lands |
|---|---|---|
| Client record | Medicaid ID as the addendum spells it, name, home address with coordinates | clients endpoint |
| Employee record | Caregiver by SSN or custom ID per the addendum; position; NPI where the state asks | employees endpoint |
| Visit record | VisitOtherID, PayerID / PayerProgram, HCPCS + up to four modifiers, UTC times | visits endpoint |
| Calls | Mobile with latitude/longitude, or Telephony with the originating phone | Calls[] |
| Manual or corrected visit | VisitChanges with the program's ReasonCode and a memo | VisitChanges[] |
| Sequence | A timestamp SequenceID that only ever rises, so a resend is an update | SequenceID |
| Verdict | Status polled by transaction id; per-record errors read back to the visit | /status?uuid= |

Questions Wisconsin agencies ask
Do our caregivers have to use Sandata's app?
No. Sandata's app is the state's free option; an agency with its own system sends visits into the same aggregator through the Alt-EVV interface. Caregivers use one app — this one — and the state gets the same data.
What does the certification involve?
Sandata issues UAT credentials under a sponsoring provider in the state, we send clients, employees and visits to their test environment, work through their checklist, and they confirm. We do this with your agency as the sponsor, at no cost to you; the software is already built and tested against the published specification.
What if the state changes its reason codes or payer IDs?
Those are settings on the aggregator account, not code. When an addendum is revised the account is updated and the next send carries the new values.
Can we start before the certification is done?
Yes. Scheduling, documents, billing and the caregiver app work from day one, and every Medicaid visit is captured with GPS and coded reasons. Visits queue for the aggregator and go the day the account is live — nothing is re-entered.
Which Wisconsin programs does this cover?
Personal care, supportive home care and home health under Medicaid fee-for-service, Family Care and IRIS — every service Wisconsin Department of Health Services requires EVV for. The provider files the Alternate EVV Attestation (F-02659) with Sandata; vendor certification takes up to three months (shorter if already certified in Wisconsin); DHS may require recertification; technical specification v2.6.

EVV, state by state
Five states take EVV from the agency directly; the rest route it through a contracted aggregator. The 51-state EVV map has the model and where the software stands in each.
