ATMS is an acronym you'll run into in NEMT, but it isn't a federal term and it isn't used the same way everywhere. In New York's Medicaid Transportation Policy Manual, ATMS stands for Advanced Transportation Management System: the billing or routing software a transportation provider uses, which has to work with the Medicaid broker's systems. Many software vendors expand it as "Approved Transportation Management System." Either way, the practical meaning is the same: dispatch and trip software whose data your state or broker will accept.
If you landed here looking for cash machines, this isn't that ATM. Different acronym, different world: this one runs Medicaid trips, not deposits.
What Does ATMS Mean in NEMT, Exactly?
A transportation management system (TMS) is any software that handles trip booking, dispatching, routing, and reporting for a fleet. In NEMT, the question is whether that software can hand trip data to the organization that pays for the ride in the form it requires. For Medicaid trips, that's usually a transportation broker (such as Modivcare, MTM, Alivi, MAS, or Access2Care), a managed care plan, or the state itself.
New York is the clearest published example. Its Medicaid Transportation Policy Manual groups ATMS with third-party intermediaries (TPIs) as the billing or routing software providers use, and tells providers to contact the transportation broker for the list of TPIs and ATMS that are compliant with the broker's software. There, "approved" in practice means "on the broker's compatible list."
Why Do States and Brokers Care Which System You Use?
Medicaid transportation dollars need an audit trail. Every trip has to be traceable back to a real pickup, a real drop-off, and an authorized trip, or the claim risks denial or recovery. Software that captures that trail automatically is far easier to audit than paper logs.
- Program integrity. Regulators want proof that a billed trip actually happened, at the time and place claimed. Federal law also sets minimum Medicaid standards for NEMT providers and drivers: no one excluded from federal health programs, a valid license for every driver, a process to address drug law violations, and a process to disclose each driver's driving history to the state.
- GPS trip verification. Some programs require it outright. Since April 3, 2023, New York has required every transportation provider to be fully GPS compliant, submitting the start point, end point, and all coordinates along the trip ("breadcrumb data") to the broker. The federal electronic visit verification (EVV) mandate from the 21st Century Cures Act is a different rule: it covers personal care and home health services, not NEMT.
- Electronic trip records. New York, for example, accepts a unique electronic signature from the driver, such as clicking to confirm trip completion, in place of a written signature, as long as the driver attests the trip was completed.
- Standardized reporting. Brokers need trip and billing data in a consistent format across every provider in their network, which only works if each provider's system can produce it.
- HIPAA and data security. Any system that stores rider information has to handle protected health information (PHI) correctly, with access controls and audit logs.
What Does "Approval" Actually Mean?
There is no national ATMS certification. When a state or broker "approves" software, it usually means the software has been confirmed to work with the broker's trip assignment and billing systems and to deliver the data the contract requires, such as GPS trip data. A system can be excellent for a taxi company and still fall short for Medicaid NEMT if it can't exchange data with the broker the way the contract requires.
For providers, this has a practical consequence: buying software before confirming what your broker, health plan, or state requires is a common, expensive mistake. Ask your broker contact for their current technical requirements before you sign a software contract, not after.
State Examples: What We Could Confirm
Requirements vary by state and broker and change over time, so treat this as a starting point and confirm directly with your state Medicaid agency and broker before making a purchasing decision.
- New York: What we found: Transportation providers must be fully GPS compliant (effective April 3, 2023) and submit breadcrumb data to the broker. Providers using TPI or ATMS software should contact the broker, Medical Answering Services (MAS), for the list of compliant systems.; Primary source: eMedNY Medicaid Transportation Policy Manual; NYSDOH Medicaid Transportation
- All states: What we found: Federal rules require state Medicaid programs to assure necessary transportation and to meet minimum provider and driver standards. How software fits in is set by each state and its brokers or managed care plans.; Primary source: Medicaid.gov: Assurance of Transportation
How to Know If Your Software Qualifies
Your software qualifies when your broker or state has confirmed it, not when a vendor says it does. Ask three questions before you buy or switch: Does it connect to your broker's trip assignment system? Does it produce the GPS or electronic trip verification your contract requires? Can it export billing and compliance data in the format your state or broker specifies? A "yes" to all three, confirmed by the broker or agency itself, is what approval looks like in practice.
Where Bambi Fits
Bambi is NEMT dispatch and scheduling software built around the records brokers ask for. Run Bambi Run assigns and schedules trips with one click, Fleet HQ shows every vehicle on a live GPS map with real-time ETAs and driver status, and Get Paid captures GPS-stamped, signature-verified trips, broker-compliant invoicing, claim tracking, and audit-ready logs. Bambi has live API connections with MTM, Modivcare, Verida, Alivi, Call the Car, and Provide A Ride. If your broker isn't on that list, confirm with the broker how trip data must be submitted before you switch any software, including Bambi.
FAQ
What does ATMS stand for in NEMT? It depends on who's using it. New York's Medicaid transportation policy uses Advanced Transportation Management System for billing or routing software that works with the broker's systems. Many software vendors say Approved Transportation Management System. Both describe trip management software whose data a Medicaid broker or state will accept.
Is NEMT's ATMS the same as an ATM (cash machine)? No. They just share letters. An ATM is an automated teller machine for banking. An ATMS in NEMT is healthcare transportation software.
Who approves an ATMS, the state or the broker? Usually the broker, working within rules the state sets. In New York, for example, the state requires GPS compliance and the broker (MAS) keeps the list of compatible systems. Ask your state Medicaid agency whether it adds any direct requirements of its own.
Does every state require an approved system? No federal rule requires one, and states handle it differently. Where a broker or health plan manages trips, its contract and provider manual spell out the data and technology requirements. Check with your state Medicaid agency and broker for the rules that apply to you.
What features do brokers usually check for? Common checkpoints include connection to the broker's trip system, GPS or electronic trip verification, standardized billing exports, and secure handling of rider information. Check your broker's current provider manual, since requirements are updated periodically.
Can I switch software without losing my approval? Usually, but confirm with your broker or state before going live on a new system that it meets their integration and reporting requirements, and ask how long their review takes.
