Allianz Germany Claim Denied? How to Appeal Your Insurance Decision

Allianz is Germany's largest insurance company and one of the world's largest insurers, with products spanning Krankenversicherung (health insurance), Hausratversicherung (household contents), Kfz-Versicherung (motor insurance), Lebensversicherung (life insurance), and Haftpflichtversicherung (liability coverage). If you have received a claim denial from Allianz Germany — whether under a private health insurance tariff, a property claim, or a travel insurance policy — you have clearly defined rights under German insurance law and structured escalation pathways available to you at no cost. Here is how to use them effectively.

Why Allianz Germany Denies Claims

Medical necessity disputes in Krankenversicherung (PKV). In private health insurance, Allianz may deny claims for treatments deemed not medically necessary (medizinisch nicht notwendig), experimental, or not covered under your specific tariff schedule. German private health insurance (PKV) is tariff-based, meaning coverage depends critically on the exact benefit schedule you purchased — and disputes often center on whether a treatment falls within the covered benefit tier.

Pre-existing condition exclusions and non-disclosure allegations. When applying for PKV, policyholders must disclose pre-existing health conditions (vorvertragliche Erkrankungen). Allianz may deny a claim by arguing the underlying condition was pre-existing and not disclosed at application, or that the claim relates to a condition specifically excluded in the policy application. Under § 19 VVG (Versicherungsvertragsgesetz), the insurer's right to void or reduce coverage for non-disclosure is limited by proportionality and the materiality of the omission.

Waiting period denials. German PKV policies typically include statutory waiting periods (Wartezeiten) — commonly 3 months for general medical treatment, 8 months for dental, orthodontic, and maternity benefits — under § 197 VVG. Claims arising during these periods may be denied, though exceptions apply for accidents (Unfall) and emergency treatment.

Causation disputes in property and motor claims. For Hausrat or Kfz claims, Allianz may dispute whether the loss was caused by a covered event — arguing, for example, that storm damage resulted from pre-existing structural weakness or that an accident involved excluded circumstances such as gross negligence (grobe Fahrlässigkeit) to an extent the policy excludes.

Technical breach of duty (Obliegenheitsverletzung). Claims may be reduced or denied for failure to meet policy obligations — such as notification deadlines, loss mitigation requirements, or documentation duties. Under § 82 VVG, however, a reduction of benefits for a breach of duty must be proportionate to the degree of fault, protecting policyholders from disproportionate penalties for minor technical omissions.

How to Appeal an Allianz Germany Denial

Step 1: Request the Full Written Denial Explanation and Your Policy File

Contact Allianz in writing and request a detailed written denial letter (Ablehnungsschreiben) specifying: the exact policy provision cited; the factual basis for the denial; and all documents relied upon in making the decision. Under the Datenschutz-Grundverordnung (GDPR) and German privacy law, you have the right to access all personal data Allianz holds about you — including the medical assessments and documentation underlying the claim decision. This data access request (Datenschutzauskunft) often reveals the insurer's internal analysis.

Step 2: Review Your Policy Tariff and Applicable VVG Provisions

Read your policy documents carefully, particularly the Allgemeine Versicherungsbedingungen (AVB — general terms and conditions) and your specific tariff schedule. Compare the denial reason to the exact policy language. Many Allianz denials misapply or overinterpret exclusion clauses. Key statutory protections under the VVG include: § 6 VVG (duty to advise); § 19 VVG (proportionality limits on non-disclosure consequences); § 28 VVG (proportionality rule for breach of duty reductions); and §§ 305–310 BGB (protection against unfair standard contract terms).

Step 3: Obtain an Independent Medical Expert Opinion for Health Claims

For PKV health insurance denials based on medical necessity, obtain a written second medical opinion (ärztliches Gutachten) from a registered specialist (Facharzt) in the relevant field who can assess whether the treatment was medically indicated according to German and European clinical standards. An independent expert opinion is highly persuasive before the Versicherungsombudsmann and in any subsequent legal proceedings. The cost of the Gutachten may itself be recoverable if you prevail.

Step 4: File a Formal Internal Complaint With Allianz's Beschwerdemanagement

Send a formal written complaint (Beschwerde) to Allianz's designated complaints office. Reference your policy number, claim number, the denial letter, your specific grounds for disagreement under the VVG and your policy terms, and the resolution you are seeking. Send via Einschreiben mit Rückschein (registered mail with return receipt) and retain a copy of all documents. Under BaFin's complaint handling requirements, Allianz must acknowledge your complaint and provide a substantive response within a reasonable timeframe.

Step 5: Approach the Versicherungsombudsmann

The Versicherungsombudsmann e.V. is Germany's independent, cost-free insurance dispute resolution service for most private insurance disputes (excluding statutory health insurance, which uses a different system). You must first have filed a complaint with Allianz and received an unsatisfactory response — or waited six weeks without substantive resolution. For disputes up to €10,000, the Versicherungsombudsmann's decisions are binding on the insurer. For disputes between €10,000 and €100,000, decisions are non-binding recommendations that carry significant practical weight. Apply online at versicherungsombudsmann.de or by post.

Step 6: File a BaFin Supervisory Complaint

File a complaint with the Bundesanstalt für Finanzdienstleistungsaufsicht (BaFin) at bafin.de/EN. BaFin supervises all German insurance companies and can investigate whether Allianz is complying with the VVG and other applicable insurance regulations. BaFin does not resolve individual monetary disputes, but its regulatory investigation creates pressure on Allianz and establishes an official record of the insurer's conduct. For complex coverage disputes or patterns of improper denial, BaFin investigation can be significant leverage.
