One procedure, two billing routes, and the route is already decided in the coding.
The case is coded after discharge; the procedures are recorded as OPS codes in the hospital information system. Whether it becomes an inpatient DRG or a Hybrid DRG depends on individual codes from a list of hundreds. The wrong route usually only comes to light when the health insurance fund sends the case back, and by then the revenue has long been booked.
1caseA procedure that could be performed as a day case is billed as an inpatient case.
6OPS codesCoding assigns six procedure codes, one of which is in the Hybrid DRG catalogue.
1missed routing decisionThe code is recorded, but not recognised as a precedence case.
2rounds of work on the same caseThe case comes back via the insurer's review and is reopened.
There is no return from billing and no rebooking, because the route is settled at the six procedure codes, and revenue leakage falls by 50%.
The 50% reduction in revenue leakage is this agent's headline figure. Six codes per case and the return via the insurer's review trace a typical case in hospital billing; none of it was counted.
