KHAG: A Reform That Ignores The Demand Shock, While Charging The Health System For It

Executive summary 

Germany’s Krankenhausreform-Anpassungsgesetz (KHAG) tweaks the mechanics of the KHVVG but leaves a structural mismatch untouched: hospital demand is rising faster than funding that reaches front-line providers. A significant driver of near-term demand is migration-related utilisation, especially first-year urgent and emergency care, as well as subsequent integration into regular care pathways. Yet the financing architecture channels most costs through health and social-care budgets, not through any ring-fenced immigration support envelope. KHAG then draws an additional €25 bn from the statutory health insurance “Gesundheitsfonds” to finance restructuring (matched by Länder co-funding to €50 bn), further tightening insurer allocations and, by extension, provider liquidity. (BMG) 

Operationally, KHAG’s one-year deferral of the new “Vorhaltevergütung”, the expansion of Hybrid-DRGs without clear cost coverage, and the re-cut of Leistungsgruppen (service groups) to ~60 plus special traumatology do not address surge demand, ED crowding, interpreter/administrative overhead, or the cash-flow impact of delayed reimbursements from social agencies. Hybrid-DRGs in particular are flagged by provider and controller groups as under-funded and bureaucratically heavy, with a real risk of activity shifting out of hospitals. At the same time, complex cases (and costs) remain. (BMG, kma Online) 

Policy bottom line: KHAG stabilises the reform process but does not stabilise hospital finances under high inflow conditions. Without (1) federal, ring-fenced co-financing for migration-linked health usage that lands in hospitals; (2) cost-covering Hybrid-DRG rates and transition protections; and (3) immediate removal of distortionary degression, providers will continue to carry rising demand with tightening net revenue.

Why is the financing design misaligned with the demand reality 

1) KHAG draws on the health fund, not an immigration support envelope 

KHAG retains the KHVVG restructuring model but changes the payer: the Transformationsfonds for 2026–2035 will be fed with up to €25 bn from the liquidity reserve of the Gesundheitsfonds (matched by Länder and others, for a total envelope of up to €50 bn). This is not new external money; it is a reallocation from the statutory health system (with expected lower insurer allocations in those years). In practice, this tightens operating space across the SHI ecosystem just as hospitals need more flexible resources. (BMG) 

Independent analyses and oversight bodies have warned that using GKV money for structure funds risks contribution pressure and a “Deckungslücke” (coverage gap) at insurers, which will ultimately flow through to providers via more complex budgets and slower growth in base rates. (vdek.com, AerzteZeitung.de) 

2) Demand growth from migration lands in health and social budgets 

Entitlements: 

• During the initial period under the Asylbewerberleistungsgesetz (AsylbLG), medical care covers acute illnesses, pain treatment, pregnancy care and vaccinations, with additional services possible in individual cases (§4, §6 AsylbLG). Since 2024, the period before alignment to near-regular benefits has been extended to 36 months, increasing the duration during which municipalities (social welfare offices) must manage approvals and reimbursements. (BAMF, BMG) 

• Under temporary protection (e.g., many from Ukraine), individuals access social support and medical care without an asylum procedure, moving into regular SGB II/XII channels; health insurance membership and contributions are administered and financed via public budgets (job centres/social assistance), not by the individual in the initial phase. (bpb.de) 

Implication: Regardless of the pathway, cash hitting hospitals flows through health insurers and municipal social agencies. It does not arrive as dedicated “immigration support” in hospital ledgers. Moreover, flat federal transfers for contribution-financed populations are frequently not cost-covering, leaving insurers to cross-subsidise from contributions—a pressure that KHAG amplifies by drawing €25 bn out of the health fund for a decade. (mags.nrw, BMG) 

3) The utilisation signal is material 

Germany registered 351,915 asylum applications in 2023, 250,945 in 2024, and c. 73,000 up to mid-2025 (Erst- and Folgeanträge combined). These figures exclude most Ukrainians under temporary protection (c. 1.2 million registered by April 2025), who still use the health system via SGB channels. The demand impact is therefore larger than the asylum series alone suggests. (bpb.de) 

 
What KHAG changes—and why that is not enough for hospitals 

Leistungsgruppen: KHAG aligns the number of service groups to ≈60 plus special traumatology, following the NRW count. That simplifies planning on paper but does not inject liquidity or staff capacity into EDs, AMU-like admission flows, or urgent diagnostics where migration-linked utilisation is visible first. (BMG) 

Vorhaltevergütung: KHAG defers key elements by one year and phases the financial impact towards 2030. Hospitals, therefore, face one more year of dual complexity (old incentives, new planning) without offsetting cash. In regions absorbing higher inflows, this creates a mismatch between fixed readiness costs and reimbursement received. (BMG) 

Hybrid-DRGs: Expansion continues while methodology and rates are contested. Hospitals report under-coverage for complex cases, a risk of “cream-skimming” in ambulatory settings, and an increase in audit/bureaucracy. If short-stay surgical activity migrates out on non-cost-covering prices while complex cases remain inside, unit costs and case-mix volatility will rise on wards and in theatres. (kma Online) 

Transformationsfonds funding source: By tapping the Gesundheitsfonds rather than budget-financed immigration/integration envelopes, KHAG loads structural reform onto the very budget that must absorb utilisation growth. That is a policy inconsistency. (BMG)

Policy briefing for hospital executives (C-suite, finance, operations) 

Risk map (12–24 months) 

• Liquidity: Insurer and municipal reimbursement may lag utilisation; health-fund drawdowns (2026–2035) tighten allocations to payers; credit lines and working-capital buffers become more critical. 

• Revenue integrity: Hybrid-DRGs bring coding, documentation and structural-proof burdens with uncertain margins; case selection by other providers may shift profitable short-stays away. (kma Online) 

• Cost base: Interpreter services, navigation, social work, safeguarding and discharge brokerage costs are rising yet are rarely recognised in tariffs. 

• Capacity & flow: EDs and intake units face variable, language-mediated case-mix, increasing LOS variance and boarding; diagnostics become a bottleneck when urgent follow-ups cluster. 

• Planning compliance: Service-group (LG) proofs and quality criteria remain decisive for commissioning; deferral of Vorhaltevergütung extends the period of dual rules. (BMG) 

Immediate actions (next 90 days) 

1. Cash-flow discipline: 

• Tighten credit-to-cash dashboards for ED, obstetrics, paediatrics and general surgery; age municipal receivables separately; escalate contestation of denied AsylbLG claims early. 
• Pre-negotiate bridge financing with house bank using discrete ED/acute volumes and asylum-related documentation trends. 

2. Hybrid-DRG readiness (if applicable): 

• Appoint a clinical-operations lead and a coding/controller lead; run shadow margin analyses per Hybrid-DRG versus DRG/EBM pathways; pull case mix thresholds (ASA class, LOS, comorbidity bundles) to define do-not-attempt scenarios. 

• Implement front-door triage criteria to avoid sub-scale Hybrid-DRG volumes with negative contribution. 

3. LG compliance & theatre planning: 

• Map OPS-linked structure proofs per LG; ensure staffing/rota meets thresholds on all recorded days; avoid avoidable de-invoicing. 

• In surgery, maintain short-stay block lists and adjust instrument sets for efficient same-day turnover, ensuring cost-effectiveness. 

4. Interpreting & navigation cost capture: 

• Establish a cost centre for language services and discharge brokerage, and tag interpreter minutes per case to support supplemental local funding requests. 

5. Regional alliances: 

• Formalise co-operation protocols with ambulatory providers on post-ED next-day follow-up to reduce avoidable observation nights and readmissions. 

• Where feasible, share clinical translators and community health workers with local councils/NGOs. 

Negotiation agenda with payers and Länder 

• Migration-linked utilisation uplift: Seek temporary surcharges or selective payments for ED triage, interpreter use and safeguarding in high-inflow districts. 

• Hybrid-DRG protection: Request transition floors (minimum per-case top-ups) for complex cases and audit-light periods during the first year. (kma Online) 

• Capital & energy offsets: Ensure your site is queued for Transformationsfonds projects that lower operating costs (energy retrofits, day-surgery flow re-design), given funding will be scarce and staged. 

Board-level KPI set to monitor monthly. 

• ED arrivals by legal status proxy (where lawful to record), interpreter minutes, left-without-being-seen rate, and ED-to-ward boarding hours. 

• Hybrid-DRG share, case margin, denial rate, days to payment (insurer vs municipal). 

• LG compliance incidents, structure-proof audit hits, and lost revenue from failed proofs. 

• Cash burn versus line capacity; scenario to breach covenants. 

 
Where KHAG itself needs correction (policy asks) 

1. Ring-fence migration-linked health costs 
Introduce an earmarked federal co-financing line that flows directly to providers (through Länder or a BAS-managed pass-through) whenever municipalities and job centres are primary payers. The objective is to protect GKV allocations—already burdened by KHAG’s draw on the Gesundheitsfonds—and stabilise provider liquidity. (vdek.com) 

2. Make Hybrid-DRGs cost-covering and simpler. 
Freeze catalogue expansion until transparent costing (InEK/InBA) demonstrates coverage for typical hospital cost structures, with reduced audit frictions and clear post-acute responsibilities. In the interim, pay add-ons for complex cases and ED-initiated conversions. (kma Online) 

3. Remove distortionary degression now. 
Delaying the abolition of fixed-cost degression penalises early movers consolidating services. KHAG should abolish it immediately to align incentives with concentration goals.  

4. Protect insurer solvency while funding transformation. 
If the Transformationsfonds stays, replace health-fund drawdowns with budget finance (taxes) or at least offset them through targeted federal transfers to the Gesundheitsfonds to avoid downstream contribution pressure. (AerzteZeitung.de) 

Concluding comment 

KHAG moves the furniture but does not expand the room. Hospitals face a double bind: higher demand linked to sustained immigration flows, and a reform that finances structural change out of the same health pot that must pay for that demand. The result is predictable: tighter insurer budgets, more provider bureaucracy, and less room to manoeuvre on the ward. 

A credible, all-of-government approach would (i) direct federal, migration-linked health money through to providers; (ii) make Hybrid-DRGs demonstrably cost-covering before mandating scale; and (iii) abolish degression immediately to reward consolidation rather than punish it. Short of that, executives should treat KHAG as a compliance and liquidity challenge, not a stabilisation package—and plan accordingly.
