Reducing public payer rejections without changing core software

Public payer rejections are rarely a software problem: they reflect an absence of systematic checks before SESAM-Vitale transmission. Most rejections fall into four families: unverified rights, care pathway misqualification, mis-qualified exemptions, or missing documentation. These four families alone concentrate over 80% of primary rejections observed in the operators we work with.

The first automation block is to systematically query the rights service before each invoice, retrieving the up-to-date patient situation: scheme, fund, exemptions, long-term conditions, maternity, work accidents. This simple check, done in real time rather than from memory or from a potentially outdated card, eliminates 30 to 40% of rights-related rejections.

The second block concerns the coordinated care pathway. Many rejections come from a missing primary care declaration or from an incorrect qualification of the consultation context. An AI agent can cross-check the consultation context, the patient profile and the applicable rules to pre-qualify the invoice.

The third block addresses exemptions. Long-term conditions, low-income coverage, regional schemes, special schemes: each case has its own pricing rules. An agent that knows these rules applies the right grid automatically, without relying on the biller's memory.

The fourth block covers supporting documents. For some procedures (transport, medical devices, long sessions), the payer requires dematerialized documents. An agent can verify their presence, legibility and conformity before transmission.

Orchestrating these four blocks transforms the billing chain. The team no longer processes rejections after the fact, on cold files weeks later. They validate upstream, while the patient is still reachable.

The operational benefit is measurable quickly: 60 to 80% of avoidable rejections disappear within weeks, without changing the core billing software. DSO drops mechanically, cash flow improves, and freed administrative time is reinvested in complex case follow-up.

ROI is immediate as soon as monthly volume exceeds a few hundred claims. For a five-practitioner group billing 4,000 procedures per month, that means 200 to 300 rejections avoided, equivalent to a day and a half of secretarial time recovered each week.

The typical rollout fits in two weeks: audit of historical rejections in week 1 to calibrate rules, supervised production launch in week 2 with systematic human validation, then progressive switch to autonomous mode on standard cases.
