Michigan EVV on the calendar
Home health came first in 2024 and personal care and the plans followed on their own dates; Home Help pay has not moved to EVV.
| Step | Date | Change | MDHHS text |
|---|---|---|---|
| Home health, fee-for-service | Apr. 1, 2024. | Six visit codes, aide to skilled nursing, enter EVV. | MMP 24-11 |
| Fee-for-service home health billing | June 1, 2024. | Claims go to CHAMPS only from HHAeXchange; direct ones are rejected. | L 24-17 |
| Home Help agencies | July 1, 2024. | Personal care visits logged in EVV. | MMP 24-21 |
| Other personal care, plus plan home health | Sept. 3, 2024. | Behavioral Health, Home Help caregivers, MI Choice, MI Health Link and health plan home health. | MMP 24-21 |
| Health plan home health billing | Jan. 1, 2026. | Hard cutover set by the letter: claims only from complete EVV records. | L 25-59 |
| Manual-edit line | Apr. 1, 2026. | 85 percent of an agency’s verified visits per quarter without a hand edit. | MMP 26-10 |
Each date is taken from the MDHHS bulletin or letter in its row; every one was opened October 27, 2026.
In MDHHS’s words
Bulletin MMP 26-10 describes the setup plainly: “Michigan implemented an open vendor model.” On hand corrections it adds that “Manual edits are accepted but should never be the primary method to capture visit information.” For Home Help, the caregiver page updated October 22, 2026 keeps the old payment route in place: “Payments will continue to be based on the data recorded on the current service verification methods until further notice.”
One vendor, two jobs
MMP 24-21 and MMP 24-11 both say the state selected HHAeXchange as its EVV vendor and its aggregator. An agency can run another product instead, paying for it itself, provided that product is validated and sends its visits on to HHAeXchange. Each agency enrolls in CHAMPS, Michigan’s Medicaid claims system, and fills in an HHAeXchange onboarding form before its first visit is logged.
Home health care
Fee-for-service home health went first. MMP 24-11 brought EVV to six procedure codes on April 1, 2024, from home health aide visits to RN and LPN skilled nursing and three therapies, and left hospice and people enrolled in both Medicare and Medicaid outside it. Letter L 24-17 then set June 1, 2024 as the point after which HHAeXchange alone builds the claim for CHAMPS. Health plan members’ home health joined on September 3, 2024 with a soft launch that carried no payment penalty; letter L 25-59 of October 14, 2025 announced its end on December 31, 2025 and set January 1, 2026 as the day claims were to start flowing only from complete EVV records. No later MDHHS text read for this page reports how that date went.
Personal care, waivers and Home Help
Bulletin MMP 24-21 started Home Help agency providers on July 1, 2024 and, on September 3, 2024, Behavioral Health, Home Help individual caregivers, MI Choice and MI Health Link. Personal care under Community Transition Services stays out for now. Three kinds of visit sit outside EVV as well: those in congregate settings such as adult foster care homes; those of an approved live-in caregiver who signs form BPHASA-2421 and shows two proofs of a shared home; and, per MMP 24-34, a single visit in which the same caregiver gives a beneficiary both Home Help and Behavioral Health personal care. MMP 24-34 has Home Help live-in status renewed every six months.
Capturing a visit, and fixing one
The HHAeXchange+ app is the preferred route, on a phone or GPS-enabled tablet owned by the beneficiary, the caregiver or the employer, and a visit clocked without signal goes through once the phone reconnects, which MMP 24-21 of May 31, 2024 wants within seven calendar days. The fallback is a pair of calls from the beneficiary’s landline to a toll-free line. MMP 26-10 lists what turns a visit into a manual edit, including a missing clock-in or clock-out, a missing caregiver, and an app visit carrying no GPS location, and it sets an 85 percent quarterly line for agency providers, FMS providers included, from April 1, 2026, checked by MDHHS for fee-for-service and by the managed care entity for its own members.
What counts as a source here
Only MDHHS pages, bulletins and letters, all listed above. No vendor post, news story or law firm note was relied on. A search of the Michigan Compiled Laws for “electronic visit verification” returned nothing, so this page cites no Michigan statute.
Not covered by this reading
The Medicaid Provider Manual’s EVV chapter, which MDHHS points to as its standing policy, did not open from this network and was not read. Health plan contracts, HHAeXchange’s technical specifications and the self-directed arrangements still under development were left aside too.
Where LockProof sits for a Michigan agency
Michigan’s EVV visits end up with HHAeXchange, CHAMPS and the plans. A LockProof photo serves a different reader, such as an adult child checking on a parent, or a client covering the cost personally. That split is covered in apps that run beside EVV tools and in a caregiver photo record, piece by piece.
Date of this reading, and nearby states
Everything above reflects MDHHS texts opened on October 27, 2026, and a bulletin issued after that may change some of it. Every covered state is listed in our state-by-state EVV index, with Ohio next door at the Ohio EVV page.
Common questions
Where does GPS come into Michigan EVV?
Only on app visits. MDHHS bulletin MMP 24-21 of May 31, 2024 lets a caregiver clock in by calling a toll-free line from the beneficiary’s landline, a route with no satellite reading at all, and sends the caregiver to the app when the beneficiary has no landline usable for EVV. GPS enters only through the HHAeXchange app: Michigan Medicaid bulletin MMP 26-10, effective April 1, 2026, puts an app visit with no GPS location reading among the manual edits, and those weigh against an agency’s quarterly figure.
Which EVV system does a Michigan agency use?
MDHHS picked HHAeXchange both to run the free state system and to collect every visit. Bulletin MMP 26-10 of February 27, 2026 labels Michigan’s approach open vendor, so a provider can bring a product of its own, at its own cost per MMP 24-21, as long as the visits reach the HHAeXchange aggregator. Home Help individual caregivers have no such choice; the state’s page for them points only to HHAeXchange.
Is Home Help paid from EVV records yet?
Not as of the October 22, 2026 update to the MDHHS page for Home Help individual caregivers. Those caregivers have logged visits in HHAeXchange since September 3, 2024, yet payment still runs on CHAMPS Electronic Service Verification or Paper Service Verification, and the page says that holds until further notice. MMP 24-34 promised word before any change.
How many visits may an agency fix by hand?
Under MMP 26-10, effective April 1, 2026, at least 85 percent of an agency provider’s verified visits in a quarter, fiscal intermediaries and FMS providers included, should carry no manual edit, counted separately for each payer. Falling short can bring retraining, assigned training, a written plan or a meeting with MDHHS or the managed care entity, whether a health plan, a PIHP or CMHSP, or a MI Choice waiver agency. Newly enrolled agencies get a grace period of one partial and one full quarter.
Can a Michigan agency use LockProof in place of HHAeXchange?
No. Michigan’s EVV system is HHAeXchange; LockProof is not an EVV system at all: CHAMPS receives nothing from it, no visit reaches the aggregator through it, and it creates no claim. What it can add is narrower, a dated photo of a visit that relatives or someone paying privately can open.
Can a Michigan provider rely on this as legal advice?
No. What it sets out is what MDHHS had published when its pages and bulletins were opened on October 27, 2026. How a bulletin applies to one agency, plan or caregiver is for counsel, the health plan or MDHHS Provider Inquiry to answer, and the Medicaid Provider Manual chapter that MDHHS treats as current policy was not part of this reading.
