What are deadhead miles in NEMT?
Deadhead miles are the miles a NEMT vehicle drives with no rider on board: from the garage to the first pickup, between a drop-off and the next pickup, and back to base at the end of the day. Medicaid pays fee-for-service NEMT providers only for loaded miles, so every deadhead mile is a cost the provider absorbs.

What counts as a deadhead mile
In NEMT, a deadhead mile is any mile driven without a rider in the vehicle. Three stretches of the day produce most of them:
- Pull-out. The drive from the garage, or the driver’s home, to the first pickup.
- Between trips. The drive from one drop-off to the next pickup, including repositioning near a clinic for a will-call return.
- Pull-in. The drive from the last drop-off back to base.
Transit agencies use the word a little more narrowly. The FTA’s National Transit Database defines deadhead as the miles and hours a vehicle travels out of revenue service, such as leaving or returning to the garage. Under that definition, a transit van driving between two scheduled riders generally counts as revenue service. NEMT billing does not work that way. It pays for miles with the rider in the seat, so NEMT operators treat every empty mile as deadhead.
Why deadhead is pure cost
Medicaid pays for loaded miles, not driven miles. CMS’s provider booklet says states and contracted transportation entities may only pay fee-for-service transportation providers for loaded mileage. Arizona’s AHCCCS manual, revised July 31, 2026, says a NEMT provider may not submit any claim for unloaded mileage. Colorado’s NEMT billing manual excludes charges incurred while the member is not in the vehicle. Fuel, wear, and driver wages on empty miles all come out of your margin.
A worked example
Here is a hypothetical wheelchair van running six one-way trips in one day.
| Segment | Miles | Paid by Medicaid |
|---|---|---|
| Garage to first pickup | 8 | No |
| Six loaded trip legs | 62 | Yes |
| Empty drives between trips | 34 | No |
| Last drop-off to garage | 9 | No |
| Total | 113 |
Deadhead is 51 of 113 miles, or 45 percent of the day. Use your own cost per mile if you track it. If you do not, the IRS business standard mileage rate gives you a reference point: 76 cents a mile for July 1 to December 31, 2026. At that rate, this van spends $38.76 a day on empty miles, or about $853 over 22 working days. Run your own numbers in the deadhead cost calculator.
How dispatchers cut deadhead
Deadhead is mostly a scheduling problem. The driving itself is rarely the cause.
- Chain trips by geography. The next pickup should start close to the last drop-off.
- Start routes where drivers are. A driver who lives near the first pickup beats one who starts at the garage.
- Cluster will-call returns. Keep a vehicle near the clinics where returns bunch up.
- Check the empty leg before accepting. A 20-mile empty drive to earn a 3-mile loaded leg can cost more than the trip pays.
Our guide on how to reduce NEMT deadhead miles goes deeper on these tactics, and the route optimization guide covers planning whole routes. High deadhead also drags down vehicle utilization and trips per hour.
Where software helps
Chaining dozens of trips by hand is where empty miles creep in. Ryder Go, HealthRide’s route optimizer, plans your whole day in one click and starts each route from where every driver actually is.
Frequently asked questions
- Do brokers or Medicaid pay for deadhead miles?
- Generally no. CMS provider guidance says states and their contracted transportation entities may only pay fee-for-service NEMT providers for loaded mileage, and state manuals such as Arizona's and Colorado's say the same. Private-pay and facility work is different, because you set those rates yourself and can build a pickup or distance charge into them.
- What is a normal deadhead percentage for a NEMT van?
- There is no official benchmark. A rural route with long drives between riders will carry more empty miles than a dense city route. Track deadhead by vehicle and by day, then compare each route against its own history instead of against a national number.
- Is the drive to a no-show pickup counted as deadhead?
- Yes. If the rider is not there, every mile driven to that address is unpaid. CMS warns that billing loaded mileage for a no-show is billing for services not rendered, so those miles can only be recorded as empty miles.
