Insurance Claim Denied in Vilnius, Lithuania? How to Appeal

Vilnius has undergone remarkable economic transformation since EU accession, with a large corporate and technology sector driving strong demand for private health insurance among Lithuanian residents and the city's growing international workforce. Private insurers active in Lithuania — including Compensa Vienna Insurance Group, Gjensidige, Swedbank Life Insurance, If P&C, and PZU Lithuania — operate under the supervision of Lietuvos bankas (the Bank of Lithuania), which provides a free consumer dispute resolution service that gives policyholders real power to challenge denials.

Why Insurers Deny Claims in Vilnius

Lithuanian private health insurance claims are denied for a predictable set of reasons, each of which has specific defenses under the Lithuanian Insurance Law (Draudimo įstatymas) and EU consumer protection frameworks.

Pre-existing condition exclusions. Lithuanian private health insurance contracts routinely exclude conditions diagnosed, treated, or present before the policy commencement date. The insurer's determination of what constitutes a "pre-existing" condition is often contested — particularly for conditions that were latent or undiagnosed at inception. Insurers cannot extend the pre-existing exclusion to conditions that were genuinely unknown at the time of policy commencement.

Treatment classified outside the policy schedule. Lithuanian private health policies specify covered services and procedures. Claims for treatments not listed — particularly alternative therapies, certain specialist procedures, or emerging treatments — are denied on policy exclusion grounds. Ambiguous policy language is subject to contra proferentem interpretation under Lithuanian contract law.

Failure to use network providers. Vilnius has a developed private clinic infrastructure, including Northway Medical Centres, Medicina Practica, and Antakalnio klinika. Many Lithuanian policies operate through preferred provider networks, and treatment at non-contracted facilities results in denial or reduced reimbursement.

Claims for treatment obtained without required authorization are denied, though emergency situations provide a recognized exception.

Waiting periods not satisfied. Lithuanian policies impose waiting periods for dental, maternity, and certain specialist services. Claims submitted before the waiting period expires are denied as a contractual matter.

Accident insurance claim disputes. For personal injury policies — widely distributed in Lithuania — disputes arise about whether an injury meets the policy's definition of an "accident," or about the degree of permanent disability sustained following the injury.

How to Appeal a Denied Claim in Vilnius

Step 1: Obtain the Written Denial Decision

Your insurer must provide a written explanation of the denial decision. If this was not provided, request it formally in writing, referencing your claim number and policy number. The denial letter defines the grounds you will challenge.

Step 2: Review Your Full Policy Document

Obtain the complete text of your insurance contract (draudimo sutartis and bendrosios bei specialiosios sąlygos). Identify whether the exclusion or condition cited in the denial actually applies to your specific circumstances when the policy is read carefully and completely.

Step 3: Gather Supporting Medical Evidence and Documentation

Compile your complete policy documentation, the written denial decision, all medical records, specialist reports, diagnostic results, referral letters, and a treating physician letter confirming the medical necessity and clinical basis for the treatment.

Step 4: Submit a Formal Internal Complaint to the Insurer

Write a formal complaint to the insurer's complaints department. Reference your claim and policy numbers. Explain specifically why the denial is incorrect under the policy wording, attach all supporting evidence, and request a written response within 30 days. Under Lithuanian law, insurers must respond to formal complaints within defined timeframes.

Step 5: File with the Bank of Lithuania's Consumer Dispute Resolution Service

The Bank of Lithuania operates a free, formal consumer dispute resolution service for insurance matters at lb.lt. This is the most important escalation route for individual policyholders.
