Germany's Bundestag Health Committee heard sharply differing views on 11 November 2026 about a Green Party bill intended to strengthen patients' rights after medical errors. Statutory health insurers and patient organisations welcomed easier access to information and damages claims. Doctors' organisations and legal experts warned that changing liability rules could shift medical uncertainty onto clinicians. The committee hearing was scrutiny of bill 21/6916, not its passage into law.
Key facts
- The bill received its first Bundestag reading on 9 July 2026 before referral to committees.
- It would generally require clinicians to disclose recognisable signs of treatment errors promptly and without being asked.
- It proposes easing proof that an established error caused a patient's harm.
- The AOK health insurer federation and patient groups support major changes; the German Medical Association and Marburger Bund have objections.
What patients can demand now
Under Section 630c of Germany's Civil Code, clinicians must explain important aspects of diagnosis and treatment in understandable terms. When they can recognise circumstances suggesting a treatment error, current law requires them to inform patients on request or when necessary to avert health risks. The Greens' bill would turn that restricted disclosure obligation into a general duty to volunteer information promptly. The patient group Fokus Behandlungsfehler argued at the hearing that people cannot investigate an incident or enforce their rights without knowing what happened.
A second proposal concerns causation: proof that an established medical error produced the harm for which compensation is sought. Even when a mistake is established, patient advocates say complex medical cases often make it difficult to demonstrate what would have happened under flawless treatment. The proposal would allow a showing that the error caused the harm with a preponderance of probability. It would not make every disappointing medical outcome automatically compensable. Courts would still examine whether an actionable error, damage and the relevant legal conditions were established.
The current Section 630h already contains specific presumptions in malpractice cases. They cover, among other situations, risks fully controlled by the provider, failure to document medically required measures, inadequate professional qualifications and gross treatment errors. The proposed reform therefore modifies an existing framework of exceptions; it is not a switch from a system with no evidential protections for patients. The extent of additional presumptions and the lower causation threshold is at the heart of the dispute.
Why insurers and doctors disagree
According to the Bundestag's hearing account, the German Medical Association warned that the draft might encourage one-sided judgments of blame, more paperwork and defensive treatment decisions. Marburger Bund, the doctors' union, opposed altering the carefully developed liability rules and suggested considering a hardship or compensation fund for particularly serious cases. Medical law scholar Christian Katzenmeier argued that where medical science cannot reliably establish a causal link, the issue is how society allocates the risk of uncertainty, not simply a missing piece of information.
The AOK federation took a more favourable view of reform. It said a stronger right to information would improve patients' legal position. But it also wanted room for health insurers to decline support in justified cases unlikely to succeed, including expired limitations periods or final court judgments. Agreement that patients need help thus does not resolve who should bear the cost and evidential burden in every lawsuit.
At the July first reading, the Greens also argued for clearer organisational responsibility at healthcare institutions, better documentation and support for resolving disputes outside court. Those issues remain part of the wider bill, even though Wednesday's expert debate focused heavily on disclosure and causation. They are opposition proposals rather than obligations already imposed on hospitals.
What must happen before rules change
The committee must work through the evidence and the parliamentary process must continue. No final vote or implementation date emerged from the 11 November hearing. Until legislation changes, patients and clinicians operate under the existing Civil Code disclosure duties and proof rules. A doctor is not newly required to follow a proposal simply because experts debated it.
The central decision is whether lowering the hurdle for an injured patient to prove causation improves accountability without turning genuine medical uncertainty into automatic liability. That depends on the eventual wording and parliamentary support, neither of which is settled by this hearing.
