How the New Coding and Payment Model Is Reshaping Hospital Care and Which Technologies Fit It Best

For 2026, the German Hybrid-DRG system underwent a significant expansion, increasing to 69 grouped Hybrid-DRGs and covering roughly 904 OPS procedure codes. The 2026 catalogue now includes procedures such as appendectomy, cholecystectomy, cardiovascular and peripheral interventions, and orthopaedic fracture treatments that historically required inpatient stays. Importantly, Hybrid-DRGs for 2026 also apply to cases with up to two overnight stays, bringing short inpatient care into the hybrid reimbursement framework. These changes expand the operational and economic relevance of Hybrid-DRG choice logic for hospitals, forcing strategic decisions about where and how care is delivered.

For 2026, the Hybrid-DRG catalogue expands from 22 to 69 distinct Hybrid-DRGs, meaning far more procedures and pathways are now eligible for sector-equal reimbursement. This triples the number of hybrid reimbursement categories available to hospitals and MVZs.

For the first time, cases with up to two overnight stays which historically were reimbursed entirely via the traditional inpatient DRG system are now eligible for Hybrid-DRG reimbursement. That means previously “purely inpatient” care is now within the hybrid/AOP choice logic, fundamentally altering hospital economic planning.

Policy backing for Hybrid-DRGs is not static. Germany aims to increasingly migrate care out of full inpatient settings. According to policy analyses, the target trajectory is:

• ~1 million Hybrid-DRG cases in 2026,
• ~1.5 million by 2028, and
• ~2 million by 2030.

This shows that Hybrid-DRG is intended to be a long-term structural driver of ambulatory care growth.

The statistical scale of the 2026 catalogue suggests that up to 900,000 formerly inpatient cases could be treated ambulatorially or hybrid-eligible, effectively setting a new baseline for cross-sector reimbursement in Germany. Some analyses even point to ~1 million patient cases shifting into hybrid reimbursement territory.

Why Hybrid-DRGs Matter More Than They Sound

Germany’s Hybrid-DRG system is often described as a technical update to hospital coding. In reality, it is one of the most important behaviour-shaping reimbursement reforms in European healthcare.

Hybrid-DRGs do not simply change how hospitals are paid.
They change:

• where care happens,
• how clinical pathways are designed, and
• which technologies hospitals are willing to adopt and fund.

For MedTech and digital health companies, Hybrid-DRGs are not a niche detail — they are a filter that determines whether innovation fits Germany’s future hospital economics.

What Is the Hybrid-DRG System in Germany?

Hybrid-DRGs are part of Germany’s sector-equal reimbursement reform under §115f SGB V.

They introduce a single national case payment for selected procedures, regardless of whether the care is delivered inpatient or ambulatory.

In practical terms:

• The same clinical activity
• Receives the same reimbursement
• Whether performed in a ward or as ambulatory surgery

This collapses the historical boundary between:

• inpatient DRG reimbursement, and
• ambulatory AOP (outpatient surgery) billing.

The technical structure of Hybrid-DRGs is defined through bodies such as InEK, with national implementation across statutory health insurance (GKV).

Why Did Germany Introduce Hybrid-DRGs?

For decades, Germany’s system paid more for inpatient care, even when ambulatory treatment was equally safe. This created structural incentives for:

• avoidable admissions,
• precautionary overnight stays, and
• inpatient care used as a financial buffer.

Hybrid-DRGs were introduced to:

• enforce the principle of “ambulatory before inpatient”,
• remove setting-based financial distortions,
• reduce bed pressure and staffing strain, and
• reward efficient, standardised care delivery.

This is not primarily a cost-cutting reform.
It is a risk-reallocation reform — shifting operational and financial responsibility onto hospitals.

How Hybrid-DRGs Work in Practice

1. A Defined Hybrid-DRG Catalogue

Only selected procedures qualify for Hybrid-DRG reimbursement. These are defined through:

• OPS procedure codes,
• diagnostic combinations, and
• exclusion and context criteria.

The catalogue is expanded and updated annually and already covers hundreds of procedures.

2. A Real Economic Choice: Hybrid-DRG vs AOP (Wahlrecht)

For eligible cases, hospitals now have a genuine choice of billing logic:

• bill via Hybrid-DRG, or
• bill via AOP ambulatory surgery.

This choice matters because:

• revenue differs,
• financial risk differs, and
• margin volatility differs.

Hospitals are no longer just coding what happened — they are actively optimising where care happens.

3. Eligibility Is Pathway-Sensitive

Hybrid-DRG eligibility depends on:

• length of stay,
• complications,
• escalation,
• timing, and
• documentation quality.

A single deviation — an unnecessary overnight stay, unplanned observation, or poor documentation — can:

• invalidate ambulatory billing,
• downgrade Hybrid-DRG reimbursement, or
• push the case back into unfavourable payment logic.

This is why Hybrid-DRGs are operational, not administrative.

What Hybrid-DRGs Are Really Used For

Hybrid-DRGs act as a system-steering mechanism.

They:

• reward predictable, protocol-driven care,
• penalise variability and informal escalation,
• favour ambulatory migration, and
• expose inefficient inpatient practice.

Hospitals that deliver:

• standardised pathways,
• low variance outcomes, and
• reliable same-day discharge

benefit economically.

Hospitals that rely on:

• length of stay as a safety buffer,
• undocumented deviation, or
• “just in case” admissions

lose.

Why Hybrid-DRGs Change Technology Adoption

Hybrid-DRGs do not reward:

• innovation in isolation,
• long-term population benefits, or
• abstract clinical improvements.

They reward technologies that:

• shorten length of stay,
• reduce variance,
• stabilise pathways,
• protect billing eligibility, and
• make ambulatory care financially safe.

This is why many technologies are now adopted off-tariff not because they are reimbursed, but because they protect revenue.

What Hybrid-DRGs Really Signal

Hybrid-DRGs are not a coding tweak.
They are a discipline-enforcing payment architecture.

They reward hospitals — and technologies — that make care:

• predictable,
• standardised,
• low-variance, and
• safely ambulatory.

For MedTech and digital health companies, the rule is simple:

If your technology increases the proportion of cases hospitals can safely run as ambulatory or Hybrid-DRG without billing risk, Germany will adopt it even without a dedicated tariff.
