Hybrid DRG Routing Agent

It is not the number of procedures that makes the case tricky. A single OPS code decides the billing route, and nobody notices.

Spots the OPS codes where the Hybrid DRG must take precedence before a case is billed as inpatient.

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.

Three steps through the process.

The agent checks every assigned OPS code against the Hybrid DRG catalogue and names the billing route that takes precedence; medical controlling remains responsible for the coding itself.

Check every code against the Hybrid DRG catalogue

The agent reads the assigned OPS codes from the hospital information system and checks them against the current Hybrid DRG catalogue. Every match is shown with code and reference.

Case 2026-114872, 6 procedure codes checked, 1 match in the Hybrid DRG catalogue

Determine the billing route that takes precedence

The agent shows which route takes precedence for this case and which detail tips the balance. If the detail contradicts the documentation, it flags the case.

Attach the review note to the case

The agent writes codes, matches and references into a review note on the case. Medical controlling sets the final coding.

What the agent does not do.

It neither assigns nor removes any OPS code.

For case 2026-114872 it checks the six procedure codes against the Hybrid DRG catalogue and names the match. Medical controlling assigns the coding and is responsible for it.

It does not bill the case.

It marks the route that takes precedence in the review note. The hospital billing specialist triggers the release of the case to the insurer.

It does not assess the medical indication.

Whether the procedure required an inpatient stay is documented in the operation report and is a matter of clinical judgement. It points to the passage, nothing more.

The questions that come up before the first meeting.

How quickly is the Hybrid DRG Routing Agent ready to use?

A pilot typically runs on your own data within 4 to 6 weeks. The agent connects to your existing systems rather than running as a separate, parallel environment.

Where is the data processed?

EU cloud, private cloud or on-premises. Processing is GDPR-compliant and models are never trained on your data. Details in the Trust Center.

Where does the figure “50% less revenue leakage” come from?

It is based on experience from comparable projects and process benchmarks, not a commitment. We work out the realistic effect for your organisation during the assessment before the pilot.
