Dispatching a mixed NEMT fleet: matching riders to ambulatory, wheelchair, and stretcher vehicles

Start with the rider’s level of service

Every dispatch decision in a mixed fleet starts with the rider’s level of service, the kind of vehicle and help the rider needs. In SMD 23-006, its 2023 letter to state Medicaid directors, CMS tells states to pick the cheapest mode among those that fit a rider’s physical and emotional condition. Its example is blunt: a wheelchair user rides in an accessible vehicle, and the state has to see that the provider delivers one.

State manuals turn that into definitions. Colorado’s NEMT billing manual is a clear example:

Other programs draw the lines differently. Louisiana’s health plan manual, updated May 28, 2026, lists ambulatory and wheelchair service and splits wheelchair into a standard level and a higher level of care, abbreviated ELOC. ELOC is a door-through-door service for riders with mobility limitations who need help when using a wheelchair, and it requires a certification from the treating physician or another listed clinician, valid for a period of no more than 180 days. The same manual has drivers help any rider who asks, between the vehicle and the building’s main entrance. Escorts, oxygen, and extra-large wheelchairs are often recorded on top of the level itself. Read the level on every trip before you look at the vehicle list.

What each vehicle can carry, and what it earns

Vehicles can usually serve their own level and the levels below it, but they are paid at the rider’s level. Colorado’s manual puts the billing rule in one sentence: bill only the procedure code that matches the vehicle type actually used and the level of service needed to carry the member. It adds that a wheelchair van bills ambulatory codes when the rider’s medical professional has not documented that the rider is wheelchair-confined, and that a mobility vehicle may use wheelchair codes only for a wheelchair user, in a vehicle fitted with wheelchair equipment.

Stretcher vans are the least portable piece of a mixed fleet. Louisiana’s health plan manual bars them from NEMT outright, along with two-door vehicles and pickup trucks. Colorado covers them with the written medical statement above. Montana covers stretcher riders under specialized non-emergency transportation and requires those providers to hold a class B public service commission license or qualify for an exemption. The stretcher vs gurney guide covers equipment and crew rules by state.

Protect wheelchair van time

The rule that keeps a mixed fleet profitable is simple: scarce vehicles go to the trips only they can run. A lift van that spends the morning on ambulatory trips earns the ambulatory rate, and the wheelchair trip it could have taken either runs late, goes to another provider, or turns back to the broker.

A placement order that works for most fleets:

1. Place stretcher and wheelchair trips first. They have the fewest vehicles that can carry them.
2. Fill spare seats on those vans with ambulatory riders heading the same way, where your contract allows shared rides and the extra stop does not stretch anyone’s ride.
3. Place the remaining ambulatory trips on cars and minivans.
4. Use a wheelchair van for a walker only when it would otherwise sit idle and the trip ends well before its next wheelchair pickup.
5. Keep some wheelchair capacity free later in the day. Will-call returns come due after appointments, and discharges can come with little warning. Louisiana expects a discharged patient to be picked up within three hours of the hospital’s call or two hours of the planned discharge time, whichever comes later.

Watch for the slow leak. A dispatcher under pressure puts one walker on a lift van because it is closest, then another, and by noon a wheelchair rider is waiting. Reviewing each day’s board for ambulatory trips on accessible vehicles, and asking why each one happened, keeps the habit in check. The dispatch workflow guide covers how to build that review into the day.

Seats and wheelchair spaces on the same van

A wheelchair van’s capacity changes from trip to trip, so plan it in seats and wheelchair positions together. The federal ADA specification for accessible vans and buses, 49 CFR 38.23, sets the basics:

• Securement locations. A vehicle up to 22 feet long needs at least one wheelchair securement location. Anything longer needs two or more.
• Clear floor space. Each securement location must have 30 inches by 48 inches of open floor.
• Fold-down seats. A securement area may have fold-down seats for other passengers when no wheelchair is using it, as long as the folded seats do not block the required space.
• Lift and ramp loads. The lift’s design load must be 600 pounds or more. Ramps of 30 inches or more carry the same 600-pound requirement, and shorter ramps a 300-pound one.

In practice, one van might carry a wheelchair rider and two seated riders on one run, then four seated riders on the next with the seats folded down. Set each vehicle’s real configurations once and plan from them. An escort or attendant takes a seat too, so count escorts when you fill a van. Check the rated load of the lift or ramp against heavier power chairs. Since November 1, 2025, Colorado pays extra-large wheelchair trips that need a second attendant to get the rider in and out, billed as A0130 plus U9. That is a reminder that some wheelchair trips need two people and not just a larger van.

Drivers are part of the match

Not every driver can run every vehicle, so the match is rider, vehicle, and driver together. Louisiana shows how the rules can split a driver pool:

• Drivers at companies with wheelchair-accessible vehicles, lift or ramp, must complete in-person wheelchair securement and passenger assistance training, refreshed no less than once every two years.
• Companies with no accessible vehicles can have their drivers take that training virtually.
• Drivers on ELOC (door-through-door wheelchair) trips add NEMTAC’s Advanced Mobility Device Securement and Certified Transport Specialist certifications, plus passenger assistance and disability awareness courses, renewed every year.
• A driver with a documented exemption from all wheelchair transports may not drive an accessible vehicle for Medicaid riders.
• Lap belts and chest straps alone are not enough for a wheelchair passenger. The driver must use a proper occupant restraint system.

Check your state’s crew rule for stretcher trips. Where a second crew member is required, a stretcher trip ties up two people, not one. Keep a simple record of which vehicles each driver is trained and cleared for, and check it when you assign trips. The wheelchair securement standards guide covers the equipment side.

Sizing the mix from your own trips

Your fleet mix should come from your trip data, not from a rule of thumb. For a sense of scale, Mississippi’s PEER Committee (Report #705, October 2024) broke down the state’s Medicaid transportation trips by mode:

Across February 2019 to June 2022, the same report found ambulatory trips at 64.3 percent, wheelchair trips at 17.4 percent, and gas mileage reimbursements at 16.8 percent. A statewide mix is only a benchmark. Your own share depends on who you contract with, so a fleet built around facility work can look very different from the state average.

To size your own fleet:

1. Count several weeks of trips by level of service, including trips you turned down or turned back.
2. Chart them by pickup hour. Look for the windows where wheelchair pickups bunch up.
3. Find the peak. The number of wheelchair riders moving at your busiest hour sets the wheelchair positions you need.
4. Count turnbacks by level. Wheelchair trips you return because no lift van is free are the clearest sign you need another accessible vehicle.
5. Price the change. A wheelchair van costs more to buy and run, and the wheelchair van cost guide and fleet size calculator help you test whether the added trips cover it.

Once you know the mix you need, the vehicle buying guide compares the options.

Doing it faster

With Ryder Go, one click plans the whole day: each trip is matched to a driver and van using pickup times, appointments, driver locations, and who needs a wheelchair van. If a wheelchair trip is headed for a van with no lift, you get a warning first, and nothing changes until you apply the plan. The dispatch board still takes drag and drop whenever you want to move a trip yourself. See Ryder Go for how it works.
