Every state Medicaid program must arrange non-emergency medical transportation (NEMT) for beneficiaries who have no other way to reach a covered medical service, an obligation set out at 42 CFR 431.53. Transportation providers, and the brokers who dispatch them, sit at the center of a benefit that state Medicaid agencies and Medicaid Fraud Control Units (MFCUs) have flagged repeatedly for weak documentation and billing that does not match the trips actually delivered. A federal audit found $14.1 million in improper Medicaid transportation payments in one state alone, and criminal cases against NEMT companies continue to be filed in multiple states. A transportation provider audit can lead to recoupment demands, payment suspension, or a referral for prosecution.
Why Regulators Focus on Transportation Claims
The U.S. Government Accountability Office reported that Medicaid Fraud Control Unit investigations produced roughly 200 criminal convictions, civil settlements, and judgments against NEMT providers across 25 states between fiscal years 2015 and 2020, most commonly for billing trips that never happened or using drivers and vehicles the state had never approved. Many states pay a per-trip or per-mile rate and rely on the transportation company's own paperwork to confirm a trip occurred.
Documentation Auditors Examine
State Medicaid programs and their program integrity contractors typically test three categories of records against every billed trip. Trip logs must show the beneficiary's name and Medicaid identification number, the actual (not scheduled) pickup and drop-off times, the origin and destination addresses, the mileage driven, and the driver and vehicle used, generally with a beneficiary or facility signature confirming the ride occurred. Eligibility verification must tie each trip to an active Medicaid beneficiary and to a covered appointment on that date. Medical necessity documentation must support why the beneficiary needed a paid ride rather than a personal vehicle, public transit, or a family member. Missing any one of these elements is enough for an auditor to disallow the claim, even where the trip in fact took place.
A trip log missing a signature, an actual pickup time, or proof the beneficiary had a qualifying appointment that day is treated by auditors the same as a trip that never happened.
Common Findings in State Audits
The HHS Office of Inspector General audited Massachusetts's NEMT program and found 86 of 100 sampled claim lines noncompliant, projecting $14.1 million in improper payments; every sampled claim lacked adequate documentation of driver qualifications or vehicle inspection and maintenance records. A separate OIG audit of Indiana's program found $3.5 million in noncompliant federal claims where the state could not confirm the beneficiary received a Medicaid-covered service on the date of transport. MFCUs have also brought fraud cases: New York's Attorney General charged a transportation company owner and office manager in 2024 with billing for fictitious trips, fabricating toll charges, and paying kickbacks to recruit Medicaid riders in a scheme valued at over $2.3 million, and Florida prosecutors charged twenty defendants in 2025 in a transportation billing scheme exceeding $5 million. The recurring patterns across these matters are phantom trips billed with no rider present, inflated or duplicated mileage, group rides billed as individual transports, and rides billed for beneficiaries who were not Medicaid-eligible or had no qualifying appointment that day.
How a Transportation Audit Proceeds
A state agency, its NEMT broker, or a program integrity contractor typically opens with a records request for a sample of billed trips, then extrapolates any error rate found in the sample across the full claims population to calculate a recoupment demand. Where the pattern looks like more than a paperwork lapse, most notably repeated phantom trips or falsified signatures, the matter can be referred to the state's Medicaid Fraud Control Unit and carries exposure under the state and federal false claims act. A provider that disagrees with an audit finding generally has a limited window to file an audit appeal before the recoupment becomes final.
Why Early Legal Counsel Is Critical
It is critical that transportation providers promptly retain experienced healthcare defense counsel upon receiving a records request, audit notice, or investigative inquiry from a state Medicaid agency, its broker, or an MFCU. Early legal intervention can protect the provider's rights, ensure appropriate responses to government requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the provider's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the provider to unnecessary risk, including referral for prosecution or OIG exclusion.
