Private clinic accounting: running T2A, GHS and PMSI like a business

A private clinic is run like an industrial services company, not like an oversized medical practice. Its revenue does not arrive as fees collected day by day: it originates from coded activity, valued through activity-based pricing (T2A), captured by the PMSI, then billed to the health insurance fund and complementary insurers. Between the completed stay and the euro collected sits a technical chain that can leak at every link. Understanding private clinic accounting in 2026 means understanding how T2A, GHS and PMSI turn into accounting revenue, and how to secure that path.

Direct answer. A commercial private clinic falls under corporate income tax and the general chart of accounts, not the BNC regime. Its revenue comes mostly from the health insurance fund through activity-based pricing (T2A and GHS), captured by the PMSI. Management rests on reconciling PMSI activity with revenue, tracking billing rejections, cost-per-stay analytics and a group structure with justified flows.

In an MCO clinic, each stay is classified into a diagnosis-related group (GHM) from the medical data, then billed to the health insurance fund through a homogeneous stay group (GHS). This capture runs through the PMSI, the medical information systems programme. In practice, the pace and quality of coding directly determine the revenue recorded.

This breaks with the logic of the self-employed physician, who keeps cash-basis BNC accounts and reports fees. The clinic bills stays, employs care and administrative staff, capitalises heavy technical facilities and falls under corporate income tax. Treating the establishment as a liberal profession under the BNC regime is the sector's most costly framing error: it distorts VAT treatment, equipment depreciation and the director's salary-versus-dividends trade-off.

A clinic's main value leak is not tax-related. It sits at the junction between medical coding, which is not the accountant's job, and billing. Incomplete coding or an under-valued stay is lost revenue that cannot always be recovered.

The accountant's role is therefore to secure the revenue chain end to end: reconcile PMSI activity with the revenue actually recorded, measure the gaps and alert management. Clinic bookkeeping without this activity / billing reconciliation remains incomplete. This control is not a refinement: it is the guarantee that the activity actually produced ends up in the accounts.

In a clinic, most collection flows through third parties (the health insurance fund, complementary insurers) rather than the patient. Third-party payment is massive. It generates multiple receivables, billing rejections to reprocess and payment terms that vary by payer.

The underestimated risk is a rejection rate that drifts slowly, without warning. A few uncorrected rejection points quickly tie up significant cash, even while the overall result looks fine. Hence an essential monthly follow-up:

• receivables by payer (health insurance fund, complementary insurers, patient co-payment);
• the stock of rejected invoices to reprocess;
• receivables ageing, built into management reporting.

This trio separates managed cash from cash simply endured.

A clinic is not steered from a global income statement. The real value comes from fine cost accounting: by unit or department (medicine, surgery, obstetrics), by operating theatre (the most capital-intensive and constrained resource) and, ideally, by type of stay, to compare the real cost with the GHS tariff collected.

Without this granularity, it is impossible to know which activities add to the margin and which destroy it. Opening an extra theatre session, choosing between two specialties, investing in heavy equipment: each decision requires a full cost per stay, not a misleading average.

Two models coexist in most establishments. Some physicians are salaried: their pay is a staff cost, with the related contributions. Others practise as self-employed within the clinic and pay a fee (redevance) for the provision of resources (premises, theatres, staff, technical facilities).

This physician fee is revenue for the clinic, not a simple neutral rebilling. Its amount, basis and treatment must be documented contractually and in the accounts. It is a recurring line that secures part of the revenue and draws particular attention in the event of an audit. Never confuse it with an employee's remuneration.

Clinics are rarely held in a single company. The most common structure combines a holding company, an operating company (often a SAS or a SELAS where the purpose requires it) and an SCI holding the walls, that is, the operating real estate.

This structure separates the real estate from operations, organises the upstream flow of cash and prepares a transfer or the entry of investors. But it demands flawless discipline on intragroup flows: SCI rents, fees, cash pooling agreements, service agreements. Each flow must be justified at its arm's-length value, on pain of reclassification. Overall consistency plays out on the parent-subsidiary regime, tax consolidation where relevant, setting the SCI rents and securing regulated agreements. For an establishment of this size, a statutory auditor registered with the CNCC is also often required, taking care not to combine incompatible engagements.

A common case in the sector: a mid-sized MCO clinic, with a sound overall result but permanently strained cash. On analysis, two causes combined. First, a billing rejection rate that had drifted without monitoring, tying up health-insurance and complementary receivables for several months. Second, an absence of analytics: a structurally loss-making unit was maintained without management knowing, masked by the other activities.

The response was methodological: a monthly follow-up of receivables by payer and of the stock of rejected invoices, and cost accounting by unit with a cost per stay. On that basis, management could renegotiate theatre-session allocation and make informed trade-offs. No result figure is disclosed here: the lesson is that analytical steering makes visible decisions that were otherwise taken blind.
