Dual eligible riders: which program pays for a NEMT trip
A dual eligible rider is enrolled in both Medicare and Medicaid. For most NEMT trips Medicaid is the payer, because Original Medicare covers non-emergency transport only by ambulance and only under strict medical rules. When both programs cover the same service, Medicare pays first. Partial duals, who get help only with Medicare costs, usually have no Medicaid ride benefit.

Full duals and partial duals
“Dual eligible” covers several groups, and only some of them have a Medicaid ride benefit. CMS sorts them into categories with numeric codes. The split that matters for transportation is between full-benefit duals, who get the whole Medicaid package, and partial duals, whose Medicaid only helps with Medicare premiums or cost-sharing.
| Category (CMS code) | What Medicaid covers | Medicaid NEMT |
|---|---|---|
| QMB Plus (02), SLMB Plus (04), other full benefit dual (08) | Full Medicaid benefits, plus help with Medicare costs | Yes, like any full Medicaid member |
| QMB only (01) | Medicare Part A and B premiums and cost-sharing | Generally no |
| SLMB only (03), QI (06) | Medicare Part B premium | Generally no |
| QDWI (05) | Medicare Part A premium | Generally no |
CMS’s transportation guide uses the same line. It defines full-benefit duals as QMB Plus, SLMB Plus, and other full benefit dual members, and ties the state’s duty to them. Indiana’s provider module shows the other side: its list of groups without NEMT includes QMB-only, SLMB-only, QI, and QDWI.
Which program pays for the ride
Medicare pays first for any service both programs cover. For rides, that overlap is small. Original Medicare’s non-emergency transport benefit is limited to ambulance. Under 42 CFR 410.40, it applies only when the beneficiary’s condition makes other ways of travel unsafe, as with some bed-confined riders. Scheduled repeat ambulance trips also need a physician certification statement dated no more than 60 days before the trip. Our guide on whether Medicare covers NEMT goes deeper.
Everything else, from sedans to wheelchair and stretcher vans, is a Medicaid ride for a full dual. CMS adds two points:
- The state must ensure a ride when a full dual is going to a service Medicaid could cover, even if Medicare pays for that visit.
- Rides to pick up Part D drugs are optional. A state may cover them in its state plan when that is cost-effective, because Part D drugs are excluded from Medicaid.
Billing order in practice
- Trips Medicare might cover. Bill Medicare first. In Indiana this applies to trips exempt from the broker, such as ambulance and stretcher transports, and the state then accepts the claim with the Medicare explanation of benefits attached, for a denial or for the remaining coinsurance and deductible. Illinois allows 24 months from the date of service to file when Medicare must decide the claim first, instead of its usual 180 days.
- Van and sedan trips. Skip Medicare. Indiana tells providers not to send brokered trips to Medicare, and to bill Verida with the trip leg ID.
- Plan members. A dual in a D-SNP may have supplemental ride benefits. CMS lets a state require those plan trips to be used up before Medicaid pays for more, since Medicaid is the payer of last resort.
Many duals sit in dual eligible special needs plans. CMS’s September 2026 report counted more than 6.4 million people in 1,082 D-SNP plans, not including employer-only group plans.
Tracking who paid for what
When one rider’s trips are split between Medicaid, a plan, and a facility, HealthRide’s payer summary breaks out each payer’s completed trips, cancellations, billed revenue, and open balance for whatever dates you choose. See reports.
Frequently asked questions
- Why was a trip denied for a member who has Medicaid?
- The member may be a partial dual. Members in the QDWI, QI, SLMB-only, and QMB-only groups receive help paying Medicare costs, not the full Medicaid package. Indiana, for example, lists all four among the groups with no NEMT coverage. Check the member's eligibility category, not just the Medicaid ID.
- Does Medicare pay for wheelchair van rides for dual eligible members?
- No. Original Medicare's non-emergency benefit is limited to ambulance transport for a beneficiary whose condition makes other transport unsafe. Wheelchair van, sedan, and stretcher van rides for full duals fall to Medicaid, or to a Medicare Advantage plan that chooses to offer rides as an extra benefit.
- Do I need Medicare's denial before billing Medicaid?
- Only for services Medicare might cover, which in practice means ambulance trips. Indiana has providers bill Medicare first for trips exempt from its broker, such as ambulance and stretcher transports, then send the claim with the Medicare explanation of benefits. For brokered van and sedan trips, providers bill the broker directly and skip Medicare.
- Does a dual eligible member need prior authorization for rides?
- Usually, the same as any Medicaid member. New York requires authorization from its broker, MAS, for dual eligible members in its long term care plans. Ambulance service at the BLS or ALS level is the exception there and needs no MAS authorization.
