Missing Authorisation Number
Trips completed without the broker authorisation that makes them payable.
The fixConfirm the authorisation before dispatch, never after the trip is done.
Trip authorisation, mileage, and level of service documented
Transportation claims are denied over details that seem trivial and are not: an authorisation number missing, mileage recorded from the wrong point, or a level of service the trip record does not support. Margins per trip are thin enough that these losses matter immediately. We make every trip billable before the vehicle moves.
Non-emergency medical transportation billing covers trips taken by patients to and from medical appointments when they cannot travel independently. Services range from ambulatory sedan transport through wheelchair vans to stretcher transport.
Most of this work is arranged through brokers rather than directly with insurers. The broker authorises each trip in advance, assigns it to a provider, and pays against that authorisation on defined terms.
That makes the authorisation number the centre of the claim. Trips taken without one, or with details that do not match what was authorised, are generally not payable, and per-trip margins leave no room to absorb those losses.
The claim is built from what the driver recorded, and there is no second chance to capture it.
Most trips are arranged and paid through a broker, and the authorisation number governs the claim.
Payable mileage generally runs from patient pickup to destination, not from your depot.
Wheelchair and stretcher transport pay more than ambulatory, and the record must support the level.
Low values per trip mean administrative errors matter far more than in higher-value specialties.
At these margins, small errors matter immediately.

Answers for transportation providers and dispatchers.
It is generally not payable, and brokers rarely authorise retroactively. The vehicle, driver time, and fuel are all spent on a trip that produces no revenue. Because transportation margins are thin, a handful of unauthorised trips each week erases the profit on many completed ones. Confirming authorisation before dispatch is the only real protection.
By odometer reading at patient pickup and again at the destination. Payable mileage generally covers the loaded portion of the trip, not the distance your vehicle travelled from the depot to collect the patient. Drivers who estimate or record total driving overstate mileage in a way that produces denials and, over time, audit attention.
The trip record showing the patient's mobility need and the equipment actually used. Wheelchair and stretcher transport pay more than ambulatory transport because they require more equipment and staff time. Billing a higher level without the record supporting it is a recognised audit pattern, so the trip sheet needs to capture it every time.
Follow the broker's specific no-show rules and document the attempt. Most networks allow some recovery when a driver arrived and waited as required, but only with evidence of arrival time and waiting period. Providers who simply write off no-shows lose recoverable revenue, while those who bill them without documentation collect denials instead.
Because member broker assignments change when plans change, and the trip may have been scheduled against outdated information. Submitting to the wrong network produces a denial and wasted filing time, sometimes pushing you past the deadline with the correct one. Verifying the member's current assignment at scheduling avoids the whole cycle.
Pickup and drop-off times, odometer readings at both points, destination details, the level of service provided, and the required signatures. Missing any element can make the trip unbillable. Requiring a complete sheet before a driver closes out their shift is far more effective than chasing details days later when memories have faded.
They are recurring, high-volume, and often authorised as a standing arrangement covering multiple trips. That makes them commercially valuable but also concentrates risk, since an authorisation problem affects many trips at once. Confirming standing authorisations remain current, rather than assuming they roll forward, protects a significant share of your revenue.
Yes, and each network has its own contracting process, rates, and submission requirements. Providers sometimes accept trips from a network before enrollment is complete, then discover the claims cannot be submitted at all. Because broker terms vary considerably, comparing them before contracting also tells you which networks are actually worth serving.
Sometimes, depending on the broker's terms and whether the patient's condition genuinely required it. Where it is allowed, the trip record must document why the attendant was necessary rather than simply noting that one was present. Providers frequently supply attendants for safety and never bill for them because the arrangement was never checked.
Revenue and denials per trip, broken out by driver, route, and broker network. That shows where documentation is failing and which networks pay reliably at rates worth serving. Providers often discover one driver or one network accounts for most of their denials, which is a specific and fixable problem rather than a general cost of business.
