Private Health Insurance Denied in Greece: Appeal

Greece's mandatory public health system — EOPYY — provides baseline coverage for all employed residents, but it leaves significant gaps: long waiting times, limited dental care, exclusions on elective procedures, and restricted specialist access without referral. To fill these gaps, millions of Greeks purchase supplementary or comprehensive private health insurance. If your private insurer has denied a claim, understanding the appeals landscape specific to the private market is essential.

The Private Health Insurance Market in Greece

Private health insurance in Greece is a competitive and growing market. The major players include:

Interamerican (owned by ACHMEA, the Dutch insurance group) is consistently ranked as the largest private health insurer in Greece by premium volume. It offers both individual and group health products and has extensive networks of contracted hospitals and clinics.

Allianz Greece offers a range of health insurance products through Allianz Hellas, including hospital care, outpatient benefits, and international coverage options.

AXA Greece (operating as AXA Asfalistiki) provides private health, life, and property products to both individuals and businesses.

Generali Hellas is part of the global Generali group and operates across life and non-life insurance lines in Greece, including private health coverage.

Eurolife ERB Insurance Group is another prominent local player with health insurance products across individual and group segments.

Private health policies in Greece typically fall into two categories: hospital-only plans (νοσοκομειακά) and comprehensive plans that include outpatient, diagnostic, and sometimes dental benefits. Hospital-only plans are the most common and the most frequently the subject of disputes.

Common Reasons Private Insurers Deny Claims in Greece

Pre-existing conditions. Greek private health insurers apply underwriting at inception, meaning conditions that existed before the policy was issued are typically excluded — sometimes permanently, sometimes for a defined waiting period. Claims that touch on a pre-existing diagnosis are among the most contested.

Waiting period violations. Most Greek private policies impose waiting periods (αναμονή) of between 3 and 12 months for certain conditions or treatments. Claims submitted during a waiting period are automatically rejected.

Cosmetic or elective classification. Insurers frequently classify procedures — particularly dermatological, reconstructive, or orthopedic ones — as cosmetic or elective rather than medically necessary. This is one of the most common grounds for dispute.

Network restrictions. Many policies reimburse treatment only at contracted hospitals and clinics. Going outside the network — even to a reputable Athens private hospital — can reduce reimbursement to a fraction of the actual cost or result in total denial.

Insufficient medical documentation. Greek insurers require specific documentation formats: original invoices, signed medical reports on headed notepaper, discharge summaries, and pathology results. Claims submitted without the complete documentation package are routinely rejected on technical grounds.

Annual or lifetime benefit limits exceeded. Comprehensive private policies carry annual limits for outpatient care, physiotherapy, mental health, or diagnostic tests. Once limits are reached, additional claims within the same policy year are declined.

How to Appeal a Private Health Insurance Denial in Greece

Step 1 — Request the full written denial. Ask for the specific policy clause(s) under which your claim was denied. This is your starting point for building a counter-argument.

Step 2 — Review your policy carefully. Read the relevant exclusions, waiting periods, and benefit limits. Identify whether the insurer's interpretation of the clause is consistent with the plain language of the contract.

Step 3 — Obtain supporting medical evidence. Ask your treating physician for a detailed letter of medical necessity. If the denial rests on a clinical judgment (e.g., "procedure is cosmetic"), a specialist opinion contradicting that classification significantly strengthens your appeal.

Step 4 — Submit a formal internal complaint. Every licensed insurer in Greece must maintain a complaints department. Submit your appeal in writing, addressing the specific denial reason, and include all supporting documentation. Request a written response within a defined timeframe.

Step 5 — Escalate to the Hellenic Financial Ombudsman (HFO). The HFO (thefdo.gr) is an independent body established to resolve disputes between consumers and financial service providers, including insurers. It is free to use, does not require a lawyer, and its recommendations carry substantial weight — all major private insurers in Greece participate in the scheme. You can file online or by post.

Step 6 — Consider legal action for large claims. Greek civil courts can adjudicate insurance contract disputes. For claims over a certain threshold, consulting an insurance law attorney may be cost-effective. Some lawyers offer contingency arrangements for clear-cut cases.

Practical Notes for Private Policyholders

• Always obtain Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization (προέγκριση) in writing before any planned hospital admission. A verbal approval from a claims phone agent is not sufficient.
• For group (employer) policies, your HR department may have a dedicated insurer contact who can accelerate the internal review.
• Keep all original invoices and medical documents — certified copies may not be accepted.
• Complaint submission to the HFO must typically occur within one year of the insurer's final response to your internal complaint.
