Home care software built for Missouri (MO) Medicaid EVV.
Missouri routes EVV through Sandata (OpenEVV Alt-EVV). First Support Homecare 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.
AI does the paperwork: faxed referrals become client records and any PDF form becomes fillable in minutes. Your staff checks and signs, so a small office keeps up without another hire.
Missouri's claim matching - what the aggregator checks
MO HealthNet runs an open model: an agency can use any EVV system that sends its visits to the state's EVV Aggregator Solution (EAS), which Sandata operates. Missouri then went a step further than logging visits - it matches every EVV-required claim against a verified visit in the EAS.
That matching ran as a soft launch from January 7, 2026, so agencies could see which claims would fail. For dates of service from April 1, 2026, it is a hard edit for the first group of providers: a claim with no matching verified visit is denied. Missouri also expects agencies to log into the EAS at least once a week to review and clear exceptions, and its rule (13 CSR 70-3) allows sanctions up to termination for providers that do not comply.
| When | What changed in Missouri |
|---|---|
| January 7, 2026 | Soft launch of EVV claims validation - mismatches reported, claims still paid. |
| April 1, 2026 | Hard launch, phase I: DSDS-authorized personal care, advanced personal care, consumer-directed, homemaker, chore and respite (provider types 26 and 28) deny without a matching EAS visit. |
| To be announced | Later phases: home health (provider type 58) and DMH Division of Developmental Disabilities services (provider type 85). |
Four reasons a claim fails
The visit was not in the EAS when the claim was submitted (or the vendor is not sending); the participant's DCN does not match; the provider ID on the claim is not the one in the EAS; or the units billed do not match the units recorded.
Send before you bill
Because matching happens at claim time, visit data has to reach the EAS before the claim goes in, not after.
Weekly aggregator review
Providers are expected to log into the EAS at least weekly to review their visits and exceptions.
Enforcement is written into rule
Non-compliance can lead to MO HealthNet sanctions under 13 CSR 70-3, up to termination of the provider agreement.
One aggregator: Sandata's OpenEVV interface
Missouri agencies live inside two sets of rules: MO HealthNet (Department of Social 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 vendor model.
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.
Everything Sandata requires is the same in every Sandata state - the element-by-element requirements, the onboarding steps and the common questions are on one page. How Sandata EVV works.

Questions Missouri agencies ask
When did Missouri start denying claims without EVV?
For DSDS-authorized personal care, homemaker, chore, respite and consumer-directed services (provider types 26 and 28), claims with dates of service on or after April 1, 2026 are denied if no matching verified visit is in the EVV Aggregator Solution.
Does Missouri's claim denial apply to home health yet?
Not in phase I. Home health (provider type 58) and DMH DDD (provider type 85) are later phases; the state has said it will announce their timeline.
Why would a Missouri EVV claim deny if the visit happened?
Usually timing or identity: the claim was billed before the vendor sent the visit to the aggregator, the participant or provider ID does not match, or billed units differ from the recorded units.
Which Missouri programs does this cover?
Personal care under the state plan and DHSS waivers, and home health — every service MO HealthNet (Department of Social Services) requires EVV for. The vendor must pass Sandata EVV Aggregator Solution interface testing; the state publishes a list of vendors currently submitting, and providers register with the aggregator.
Is there a free trial for Missouri agencies?
Yes. Missouri agencies that bill Medicaid and sign up by December 31, 2026 get 90 days free with no limit on clients: scheduling, the caregiver EVV app, documents, billing and the family portal. AI features are not part of the trial. Private-pay-only agencies get 15 days.
