EVV in Montana: Aggregator, Approved Vendors, Reason Codes and Deadlines (2026)
Montana Medicaid EVV explained for home care agencies: the Netsmart Mobile Caregiver+ state system, open vendor model, which services need EVV, the July 2024 compliance date, reason codes and how to fix a denied claim.
Short answer. Montana DPHHS uses an open vendor EVV model. Its state-provided system is Netsmart Mobile Caregiver+, free to providers, and alternate systems certified for Montana Medicaid must integrate with it. Full EVV compliance has been required for dates of service on and after July 1, 2024. Check a visit before billing with the EVV visit checker.

Which vendors are approved in Montana?
Any alternate EVV system certified for Montana Medicaid that integrates with Mobile Caregiver+ to send visit data to DPHHS. The state system is free; an alternate is at your cost. Confirm your vendor’s Montana certification before your first Medicaid visit.
Open or closed model, and what it means for you
Open: caregivers clock in and out in Mobile Caregiver+ or a certified alternate, the visit reaches DPHHS through Mobile Caregiver+, and the claim is matched against it. If no accepted visit gets there, the claim denies no matter how good the paper record is.
The six elements every visit must carry
Type of service, individual receiving the service, individual providing the service, date, location, and start and end time. Missing any one is a rejected visit. The usual failures: a missing clock-out, a caregiver not linked to the agency on that date, and a check-in away from the home with no reason recorded.
Rounding and units
Personal care is usually billed in 15-minute units. Montana’s fee schedule and provider manual set the unit and the rounding rule for each service code, so check them for the codes you bill. Convert minutes with the units calculator.
Reason codes
Montana’s exact reason codes and their wording are set in Mobile Caregiver+. These are the kinds of reasons it asks for:
| Reason | When to use it |
|---|---|
| Missed clock-in or clock-out | The caregiver forgot to check in or out; the visit is entered manually |
| Device or app problem | Phone, app or battery failed during the visit |
| No signal at the home | Location could not be captured |
| Member refused or unavailable | The member would not use the phone or device |
| Service in the community | The visit took place away from the home |
| System outage | A confirmed outage of the state or vendor EVV system |
Use the most specific reason. Payers audit free-text “Other” and repeated manual entries by the same caregiver.
Grace window
We did not find a set grace period for late clock-ins in Montana’s EVV guidance. Small differences from the schedule usually pass; the EVV visit checker flags visits more than 15 minutes off schedule so you can add a reason first. Your health plan contract may set a tighter threshold.
Deadlines and the correction window
Full EVV compliance has been required for dates of service on and after July 1, 2024. Fix the visit in Mobile Caregiver+ or your alternate system, confirm it is accepted, then resubmit the claim through Montana Medicaid. Check the timely filing limit in your provider manual.
If a claim denies for EVV
- Find the visit in your EVV system and read the rejection reason.
- Fix the element (member ID, service code, times, location) and attach the reason code.
- Confirm the aggregator shows the visit as accepted or verified.
- Resubmit the claim. Do not resubmit before step 3; it denies again.
How Caregiver Scheduling handles Montana EVV
Caregiver Scheduling captures the six elements with geofenced GPS check-in, logs an override reason when GPS can’t confirm the location, and flags late and missed check-ins for the office. In Montana, Medicaid visits have to reach DPHHS through Mobile Caregiver+, from the state system or a certified alternate, so ask us how that works for your agency. GPS check-in and EVV.
