Somewhere in Germany right now, a hospital administrator is staring at a spreadsheet and wondering how a building full of sick people - all of them insured, all of them being treated, all of them generating billable activity - can possibly be losing money.

The answer is a bureaucratic structure so complex it has three names. The full one is the Ausgegliederte German Diagnosis Related Groups system - AGDRG for short, though almost nobody calls it that. Most people just say DRG. It is the formula that determines exactly how much money a German hospital receives every time it treats a patient. A broken foot, a liver transplant, a premature birth - there is a code for all of it, a multiplier attached to that code, and a regional base rate that turns the multiplier into euros.

The system was designed to be efficient. Instead, it has produced a healthcare economy where two-thirds of all German hospitals are running at a loss, where nursing staff have been systematically cut to manage costs, where a surgeon once falsified patient records to hit a transplant quota - and where the number of hospitals in Germany has fallen by roughly 25 percent since 1990, even as the population ages and demand for care keeps climbing.

A recent video by German educational channel Mysteriös & Komplex broke down exactly how this system works - and why it produces the incentives it does.

The background

German healthcare is built around a concept called statutory health insurance - a mandatory public insurance system that covers the vast majority of the population. When a German resident goes to hospital, they do not negotiate a price or receive a bill. Their insurer - the Krankenkasse, or health fund - pays the hospital on their behalf. The patient is essentially invisible to the financial transaction.

That arrangement removes one of the main forces that normally keeps prices in check: a buyer who cares what things cost. When you book a freight shipment, both sides negotiate, because both sides have skin in the game. In hospital care, the patient does not pay and therefore has no incentive to choose cheaper treatment. Shopping for the lowest-cost cardiac surgery does not make sense when you are having a heart attack.

So Germany did what most countries with similar systems do: it fixed the prices in advance. Every year, a national catalogue is published listing thousands of medical procedures, each assigned a DRG code - a classification number that groups similar diagnoses together. Each code carries a Bewertungsrelation, a decimal number that acts as a weight. That number is multiplied by a regional base rate, the Landesbasisfallwert, which varies by state and is negotiated annually between hospitals and insurers. The result is the Fallpauschale - a flat fee the hospital receives for treating that patient, regardless of how long treatment takes or what complications arise.

For a straightforward foot surgery in Hamburg, the code i20C produces a Fallpauschale of around 5,000 euros. For a complicated spinal disc operation, a similar-complexity code returns slightly less. Organ surgeries, long stays in intensive care, and premature births can reach six figures.

The system went live in 2004. Its designers intended it as a discipline tool: hospitals would have to operate efficiently, because they could not charge more by doing more. But efficiency and healthcare do not map neatly onto each other - and the gaps in that mapping are where the problems live.

What is actually happening

The logic of a flat fee is simple in theory. In practice, it creates a hospital economy full of strange incentives.

The Fallpauschale table does not just set a price. It also specifies a minimum length of stay and a maximum. If a patient leaves before the minimum - say, the same day as surgery - the hospital faces a financial penalty, losing nearly half the flat fee. If a patient stays past the maximum, the hospital receives only a small daily top-up, typically around 300 euros per extra day, which rarely covers the actual cost of care. Everything between those two limits costs the same whether the patient is there for two days or twelve.

In that window, the only way to improve the financial outcome is to reduce costs. For two decades, the easiest cost to cut was nursing staff. Whether one nurse cares for five patients or ten does not change the Fallpauschale. So hospitals steadily reduced nurse-to-patient ratios until the problem became visible enough that lawmakers responded. In 2020, nursing costs were separated from the flat fee entirely - hospitals now negotiate a daily nursing rate directly with insurers, and those funds must be spent on nursing. Gains cannot be extracted from that pool.

That reform addressed one symptom. It did not fix the underlying architecture.

Hospitals also discovered that the DRG system rewards careful paperwork as much as careful medicine. A profession called medizinisches Controlling - medical controlling - emerged specifically to ensure that every procedure is assigned the most accurate, and most financially advantageous, code. The video compares it to tax preparation: a basic filing leaves money on the table, a thorough one surfaces legitimate deductions, and with expert help, you can maximize the return without breaking the law. All versions are legal. The outcomes differ.

Some hospitals, according to investigations by WDR and Der Spiegel, crossed that line - documenting injuries as more severe than they were, or billing for procedures that were not performed, to shift a case into a higher-paying code. Researchers have described this practice as "upcoding" - inflating the apparent severity of a case to reach a more expensive billing category.

Then there is the ventilator problem. Fallpauschale rates for patients requiring assisted breathing are tiered by total hours of ventilation. Cross a threshold and the hospital jumps to a higher payment band. One extra hour of ventilation, if it tips a case past a threshold, can be worth thousands of euros. From a medical standpoint, the consensus is to ventilate patients for as short a time as possible. The system creates a moment - just before a threshold - where financial logic and clinical logic pull in opposite directions.

The money trail

The Fallpauschale was never intended to generate profit. Its designers conceived it as a cost-recovery mechanism. Hospitals would receive enough to cover operating expenses - staff, equipment, medicines, overhead - and the federal states (Bundesländer), which hold constitutional responsibility for hospital infrastructure, would fund capital investment separately. New buildings, new MRI machines, roof repairs: that money was supposed to come from the state budget, not from treatment revenue.

This arrangement is called duale Finanzierung - dual financing. In principle it is elegant. Operating costs are covered by insurance payments; capital costs are covered by government. Nobody has to make profit from treating sick people.

In practice, the states have systematically underinvested. According to the Leibniz Institute for Economic Research, hospitals need to reinvest roughly 8 percent of annual revenue to stay current with equipment and building maintenance. States currently fund around 4 percent - exactly half of what is required.

The gap has to come from somewhere. For public hospitals, which cannot raise private equity, the only option is to extract more from the Fallpauschale than it was designed to deliver. That means finding ways to code more aggressively, concentrating on high-margin procedures, and avoiding the treatments that reliably lose money - maternity wards, geriatric care, rural emergency services.

The financial results are not ambiguous. According to the Roland Berger Krankenhausstudie 2025, three out of four German hospitals ended 2024 in deficit, with nearly 89 percent of public facilities facing serious financial distress. Germany would need around 10 billion euros to close the annual funding gap, according to the German Hospital Federation. Hospital managers surveyed by Roland Berger believe the total number of hospitals will fall from roughly 1,900 to around 1,250 by 2033.

The 2025 hospital reform law - the Krankenhausversorgungsverbesserungsgesetz, or KHVVG - attempted to restructure how hospitals are classified and funded, shifting some reimbursement toward verified structural capability rather than pure case volume. Health minister Karl Lauterbach described it as the biggest hospital reform in 20 years. It marks the most consequential restructuring of German hospital financing since 2003. Critics, however, note that the Ministry of Health simultaneously capped reimbursement growth at 2.98 percent, well below actual inflation - undermining the reform's own objectives before they could take effect.

The structural dynamic also extends to clinical decision-making in ways the code-tables make visible. Bonus arrangements in surgeon contracts - paying per procedure above a threshold - were common practice before 2013. A surgeon at the University Hospital in Göttingen who performed more than 20 liver transplants annually received a bonus of 1,500 euros per additional transplant, up to a ceiling of 60. He performed 59 transplants in the first year of the arrangement and 58 in the second. When the bonus clause expired, the number dropped to 31.

The mechanism worked. The damage was the mechanism.

What people are doing about it

Patients rarely see any of this. The transaction between insurer and hospital is invisible to the person in the bed. But the downstream effects are becoming harder to miss.

Maternity wards have been closing across Germany as childbirth - complex, staff-intensive, and billed at rates that often fall below actual cost - becomes financially unviable. Closures of hospitals, departments, and sites are already forcing patients to travel further, eroding regional access to care.

Hospital staff have started speaking out publicly. In the comments of the Mysteriös & Komplex video, a hospital worker described systematic scheduling of unnecessary tests - not because they were medically indicated, but because they generate additional billing codes. An IT director at a clinic described his own employer hiring an external firm to scan patient files automatically every month, generating tens of thousands of euros in additional billing revenue that justified the scanning contract's cost. He quit after 18 months.

Between July 2022 and October 2024, 61 hospital sites in Germany filed for insolvency proceedings, with 13 closures confirmed to date. The healthcare and nursing sectors were identified as particularly hard hit in 2025, with several large-scale insolvency cases among the year's record corporate failures.

The 2013 Göttingen scandal - in which a transplant surgeon was charged with manipulating patient records to make his patients appear sicker and therefore higher-priority for donor organs - led directly to a ban on procedure-volume bonuses in surgeon contracts. Tampering with medical data was not a criminal offense at the time it occurred, and the surgeon was ultimately acquitted by both a state court in 2015 and a federal court in 2017. The law was subsequently updated; falsifying transplant documentation became a criminal offense in 2013. But as the video notes, contracts can still tie bonus payments to departmental revenue targets rather than procedure counts - a slightly more abstract version of the same incentive.

Some hospitals are consolidating voluntarily, merging departments across campuses to concentrate high-complexity procedures where they can be performed at scale. Others are converting unprofitable inpatient services to outpatient clinics, which operate under different billing rules. A new hospital category - cross-sector Level 1i facilities - is being introduced under the 2025 reform to bridge the gap between outpatient and inpatient care, particularly in rural and underserved areas.

The bottom line

Germany designed a healthcare pricing system meant to reward efficiency without rewarding greed - and produced a system that rewards neither particularly well. Flat fees set below true cost forced hospitals to find money through coding, volume, and selective treatment. States funded half the capital investment hospitals needed and called it infrastructure policy. The result is a hospital sector where three-quarters of facilities lose money, where nursing wards have been systematically stripped, where the number of hospitals has fallen by a quarter since 1990, and where a bonus clause attached to a liver transplant surgeon's contract once produced one of the worst medical scandals in postwar German history. The 2025 reform restructures the classification system and promises new funding mechanisms. It does not resolve the tension at the center of the whole arrangement: that Germany is still asking hospitals to behave like businesses while treating a product - human health - that markets have never been particularly good at pricing.

Summary

Who: German hospitals, statutory health insurers (Krankenkassen), federal state governments, and the patients caught between them.

What: A flat-fee billing system called the DRG (Diagnosis Related Groups) pays hospitals a fixed amount per patient based on diagnosis codes rather than actual treatment costs. Because states have chronically underfunded capital investment - providing roughly half of what hospitals need - hospitals are forced to extract profit from a system not designed to produce it. Two-thirds of German hospitals are currently losing money; three-quarters ended 2024 in deficit.

When: The DRG system was introduced in 2004. The financial deterioration has been accelerating since roughly 2022, reaching a crisis point in 2024 and 2025. A major reform law took effect January 1, 2025.

Where: Germany, across all 16 federal states. The problem is most acute in rural areas and for small hospitals without the volume to generate cross-subsidies.

Why: The system was designed to make hospitals operate efficiently, but the flat fee was set at cost-recovery rather than profit-generating levels. State investment that was meant to fund infrastructure never fully materialized. The gap between what hospitals receive and what they actually spend has widened under inflation, creating financial pressure that distorts medical decision-making - from nurse staffing to billing practices to, in the most extreme case, the manipulation of organ transplant waiting lists.
