Insurance Claim Denied in Greece? How to Appeal

Greece operates a dual system of public and private health coverage, with the public EOPYY programme complemented by a growing private insurance sector. Whether your denial involves a statutory health claim or a private insurer, Greece's regulatory framework provides formal and free channels to challenge the decision — including a powerful public ombudsman service.

Why Insurers Deny Claims in Greece

Greece's public health insurance system operates under EOPYY (Εθνικός Οργανισμός Παροχών Υπηρεσιών Υγείας), providing coverage to employees, pensioners, and their dependents alongside EFKA (the unified social security entity). Private insurance is regulated by AEAPP — Αρχή Εποπτείας Ιδιωτικής Ασφάλισης under the EU Solvency II framework. Major private health insurers include Interamerican, Eurolife, Allianz Hellas, Ethniki Asfalistiki, and AXA Insurance.

Common denial grounds include: EOPYY treatment not on the positive list (θετική λίστα φαρμάκων); referral to a non-contracted healthcare provider; pre-existing condition exclusions applied broadly by private insurers; treatment classified as not medically necessary by the insurer's medical advisor; motor insurance fault attribution disputes; and home insurance damage classification disputes between peril categories.

Under Greek and EU law, AEAPP-licensed private insurers must handle claims in good faith, provide clear written denial reasons with specific policy clause citations, and comply with EU Solvency II and Insurance Distribution Directive (IDD) consumer protection standards. For EOPYY public insurance disputes, the administrative law framework applies.

How to Appeal

Step 1: Request the written denial with specific grounds

Your insurer must provide a written explanation of denial. For EOPYY disputes, request the ενημερωτική επιστολή απόρριψης (denial notification letter) specifying the grounds. For private insurance, request the specific policy clause and factual basis in writing.

Step 2: Gather your supporting documentation

Collect your policy document or EOPYY membership and entitlement documentation, the denial letter with specific grounds, medical records and specialist reports, prescriptions and referral letters, receipts for out-of-pocket costs, evidence of EOPYY enrollment or premium payment records, and any independent medical opinions supporting the necessity of treatment.

Step 3: File an internal administrative complaint (Ένσταση) — EOPYY

File a written complaint (ένσταση) with your local EOPYY office or through the EOPYY central administration (eopyy.gov.gr). Specify the denied service, the legal basis under which you believe it is covered, and attach all supporting documentation. For private insurance, write a formal complaint to your insurer's complaints department citing your policy terms.

Step 4: Escalate to AEAPP or the Συνήγορος του Πολίτη

For private insurance complaints, file with AEAPP (aeapp.gov.gr). For EOPYY public insurance failures, escalate to the Synigoros tou Politi (Συνήγορος του Πολίτη / Ombudsman) at synigoros.gr — a free, independent institution that investigates complaints about EOPYY and EFKA. Many EOPYY denials are reversed after Ombudsman intervention.

Step 5: ΕΑΕΕ Mediation for private disputes

The Hellenic Association of Insurance Companies (ΕΑΕΕ) at eaee.gr operates consumer information services and may facilitate mediation between policyholders and member insurers. Contact ΕΑΕΕ for referral before pursuing court proceedings.

Step 6: Courts — Administrative or Civil

For unresolved EOPYY disputes, proceedings at the administrative courts (Διοικητικά Δικαστήρια) are available. For private insurance disputes, the Eirinodikio (Justice of the Peace) handles claims up to €20,000 with a simplified procedure. Larger claims go to the Protodikeio (Court of First Instance).

What to Include in Your Appeal

• Policy document (for private insurance) or EOPYY membership documentation
• The denial letter with specific grounds stated
• Medical records, prescriptions, referral letters, and specialist reports
• Receipts for any out-of-pocket costs incurred
• Independent medical opinions supporting the necessity of treatment
