CPAM-approved taxi: how to get approved for seated patient transport
Becoming a CPAM-approved taxi opens access to seated patient transport, but requires a convention, a local quota, a discount and third-party payment. What it really changes for your bookkeeping and cash flow.

Quick answer. To become a CPAM-approved taxi, you must hold a valid parking authorisation (ADS), operate the attached vehicle, then sign the departmental standard convention with the local health insurance fund (CPAM), under article L322-5 of the social security code. This approval lets you bill the Assurance maladie for medically prescribed seated patient transport, with third-party payment and a 10 % VAT rate.
A taxi that carries patients does not therefore bill the CPAM. The difference comes down to one precise document: the departmental convention. Without it, the customer pays the full fare and handles their own reimbursement. With it, your vehicle becomes part of seated medical transport, with a recurring flow of trips, but also an imposed tariff framework, an agreed discount and a collection delay to steer. This shift, both a commercial opportunity and a management constraint, is what we detail here, drawing on the taxi files we handle.
What is CPAM approval (conventionnement)?#
Seated patient transport prescribed by a doctor can be covered by the Assurance maladie. But a taxi cannot bill these trips to the CPAM by default: it must first be approved (conventionné).
In practice, approval is the signature of a standard convention, specific to each department, between the taxi operator and the CPAM. This convention sets the framework for coverage: applicable tariffs, agreed discount, billing and third-party payment rules. The legal basis is article L322-5 of the social security code, which governs covered transport costs and their approval.
Without this convention, a taxi remains a standard taxi: it can carry patients, but the customer pays the full fare and may seek reimbursement themselves. With the convention, the taxi becomes part of seated medical transport and gains access to a recurring patient base, often referred by care facilities, dialysis centres or oncology units in a given area.
This patient base has a feature that is valuable in management terms: it is regular and predictable. A patient treated for a long-term condition makes repeated trips at a known frequency. That is the opposite of a street fare, random by nature. Approval is therefore not just an administrative status: it reshapes the very structure of your turnover.
What are the conditions for approval?#
Three basic conditions frame access to approval:
- holding a valid parking authorisation (ADS), the title that allows operating as a taxi;
- actually operating the vehicle attached to that ADS;
- filing a request with the departmental CPAM and signing the standard convention offered.
In taxi start-up or business-takeover files, it is often the sequencing of these steps that creates friction. The ADS is obtained or transferred under local rules, and the approval request comes afterwards. It is wise to plan the timeline, because approval is neither automatic nor instant.
We regularly see operators treat the two subjects, the ADS on one side and the CPAM convention on the other, as if they were mechanically linked. They are not. You can hold a fully compliant ADS and still not get approval, for a reason beyond your control: the quota. Before investing in a licence counting on seated transport revenue, secure this point first.
Why is the departmental quota decisive?#
An often underestimated point: approval is subject to a quota. Each department sets a maximum number of approved taxis, a form of local numerus clausus. When that quota is reached, your request may be placed on a waiting list.
This is strategic information before any installation project geared towards medical transport. If you buy an ADS counting on seated transport revenue, first check whether approval is available in the target department. An equipped vehicle and a valid ADS do not guarantee immediate access to the convention.
The concrete risk is financial. Picture a project built on a forecast where approved trips represent half of expected revenue. If the quota is saturated and you remain on a waiting list for several months, the whole balance of your first year shifts. The licence is tied up, the vehicle is financed, but the flow of referred trips does not arrive at the planned pace. This gap between the investment committed and the actual revenue is one of the costliest pitfalls we see on these files.
Hayot Expertise tip. Before signing a purchase commitment for an ADS in a project centred on medical transport, get written confirmation that approval is available in the department. A valid licence is not the same as a signed convention. We systematically include this check in the project study phase, alongside the vehicle financing plan.
Conventional tariffs and discount: what is the entry price?#
By signing the convention, you accept two major counterparts.
First, approved trips follow a tariff framework defined by the convention, distinct from your usual pricing freedom on standard trips. You no longer freely set the fare: it falls within the conventional scale.
Second, in exchange for third-party payment and access to this patient base, you grant a discount on the applicable prefectural tariff. The rate of this discount is negotiated in the convention and varies by department. In other words, an approved trip is billed at a level lower than an equivalent standard trip. That is the entry price for a regular, addressed flow of business.
This point should be reasoned as a trade-off, not as a pure loss. You exchange a lower unit margin for more predictable volume and a much reduced customer default risk, since the mandatory share is paid by the Assurance maladie. The question is not "is the discount penalising?" but "do volume and regularity offset the discount, given my fixed costs?". This is exactly the kind of calculation we run with the operator, actual discount rate in hand, before validating the direction of the project.
How do third-party payment and CPAM billing work?#
The approved taxi applies third-party payment: the patient does not pay the share covered by the Assurance maladie. You bill that mandatory share directly to the CPAM, usually by electronic transmission, with the supporting documents sent (a scanning system such as SCOR).
The effect on cash flow is concrete: you complete the trip, but collection of the CPAM share happens with a delay. This share must be tracked as a receivable, just like a customer invoice awaiting payment. The higher the share of your turnover coming from approved trips, the more this delay weighs on your working capital requirement.
In practice, approved billing runs in a few steps:
- complete the trip on medical prescription, keeping the transport voucher.
- assemble the billing file with the required documents and the prescription.
- electronically transmit the mandatory share to the CPAM and scan the supporting documents via a system such as SCOR.
- track the payment status and record the CPAM receivable in your accounts.
- reconcile the collection on receipt and identify any rejections to correct.
The item to watch closely is billing rejections. An incomplete file, a poorly filled prescription or a missing document pushes back collection, sometimes by several weeks. On a large volume, the build-up of untreated rejections silently inflates your CPAM balance outstanding and tightens your cash flow without the cause being visible at first glance.
Which VAT rate and what management impact?#
Passenger transport, including seated patient transport by taxi, falls under the reduced VAT rate of 10 % (article 279 of the general tax code). This rate applies whether the trip is standard or approved. The medical nature of the transport does not change the rate: it is the passenger transport activity that determines the VAT, not the status of the passenger.
On the steering side, approval transforms the business model. You gain a recurring, identified flow, but you bear a payment delay and a tariff discount. Profitability therefore no longer reads trip by trip: it is steered on three levers, the volume of activity, the CPAM collection time, and the mix between approved and standard trips.
| Criterion | Standard taxi | CPAM-approved taxi |
|---|---|---|
| CPAM convention | Not required | Mandatory (art. L322-5 CSS) |
| Access to reimbursed seated transport | No | Yes, on medical prescription |
| Pricing freedom | Prefectural tariff | Conventional framework and discount |
| Payment | Immediate collection | Third-party payment, CPAM delay |
| Bookkeeping tracking | Daily takings | Takings plus CPAM receivable to track |
| Customer default risk | Low (immediate payment) | Very low (public payer) |
| VAT | 10 % | 10 % |
Specific cases#
A few situations come up frequently and deserve tailored treatment:
- Takeover of an already-approved business. On a sale, the CPAM convention and the ADS are not transferred under the same conditions. Check in advance whether the buyer will have to re-file an approval request and whether the local quota allows it.
- Mixed taxi and seated medical transport activity. Most operators keep a share of standard trips. The accounts must then clearly separate the two flows, which conditions the tracking of margin and of CPAM receivables.
- Multiple vehicles and drivers. As soon as you operate several ADS or employ drivers, tracking takings per vehicle and reconciling CPAM billings becomes a real steering issue, to be properly tooled.
- Choice of legal form. Operating through a company or staying as a sole trader has consequences on how takings are taxed and how you are paid. A scoped review with your accountant is worthwhile here.
Points to watch#
Several blind spots recur in the files we handle:
- Confusing the ADS with approval. Holding the licence gives no vested right to the convention. The quota can block access.
- Underestimating the collection delay. The CPAM share is a receivable, not a same-day takings line. Without dedicated tracking, cash flow tightens with no clear warning.
- Neglecting billing rejections. Every rejected file is a delayed collection. Handling rejections must be a routine, not an end-of-month catch-up.
- Building an over-optimistic forecast on approved trips. A mix depending 100 % on the approved flow exposes you to both the quota and the payment delay.
- Forgetting to separate takings in the accounts. Without splitting approved and standard trips, you lose visibility on your real margin per segment.
Our accountant's analysis#
In a recent takeover of a taxi business geared towards medical transport, the operator reasoned solely in turnover. On paper, approved trips brought a reassuring volume. In reality, cash flow tightened as early as the second month: trips were completed, but the CPAM share arrived late, and several files had been rejected for want of complete documents. Turnover was rising, cash flow was falling. A classic third-party payment paradox.
Our reading is as follows. Approval is an excellent lever to stabilise turnover, because it secures a recurring, referred flow with almost no customer default risk. But it shifts the risk: from commercial risk to cash-flow and billing-quality risk. Profitability is no longer won at the wheel alone, it is won in the rigour of the back office, the tracking of CPAM receivables, the handling of rejections and the steering of the activity mix.
Our concrete recommendation: never build a medical taxi project on the approved flow alone. Keep a share of standard trips to cushion the payment delay, provision the CPAM share as a genuine customer receivable, and set up monthly monitoring of the actual collection time. It is this three-lever steering, volume, delay, mix, that separates a profitable file from one under constant pressure.

Frequently asked questions
Do I have to be approved to carry patients by taxi?+
No to carry them, yes to bill the trip to the Assurance maladie with third-party payment. Without a convention, you can take a patient on board, but they pay the full fare and handle any reimbursement themselves.
Is approval granted automatically if I hold an ADS?+
No. A valid ADS is a necessary condition, but approval is subject to a departmental quota. If the local quota is reached, your request may be put on a waiting list, even with a compliant vehicle.
Which VAT rate applies to seated patient transport?+
The reduced rate of 10 % applies, as passenger transport under article 279 of the general tax code. This rate applies to both standard and approved trips.
Why does my cash flow tighten while my turnover rises?+
Because third-party payment delays collection of the CPAM share. You complete the trip immediately, but the money arrives later, after billing and electronic transmission. The higher the approved share, the more this delay weighs on your working capital requirement.
Is the discount granted to the CPAM the same everywhere in France?+
No. The discount rate is negotiated in the departmental standard convention and varies from one department to another. You therefore need to check the actual rate applicable in your department before steering your activity towards approved trips.
What happens if a billing file is rejected by the CPAM?+
The rejection pushes back collection until the file is corrected and re-transmitted. A missing document or a poorly filled prescription is enough to block payment. Regular monitoring of rejections prevents the build-up of an unpaid balance.
Key takeaways#
- Approval rests on signing a departmental standard convention with the CPAM, based on article L322-5 of the social security code.
- A valid ADS is necessary but not sufficient: the departmental quota can place your request on a waiting list.
- The counterpart of third-party payment is a discount on the prefectural tariff, negotiated and varying by department.
- The CPAM share is a receivable to track: third-party payment delays collection and weighs on cash flow.
- Seated patient transport falls under 10 % VAT (article 279 of the general tax code), like any passenger trip.
- Profitability is steered on three levers: activity volume, CPAM collection time, and the mix between approved and standard trips.
