Health Insurance Claim Denied in Poland: Guide

Poland's healthcare system blends mandatory public insurance through the NFZ with a growing private insurance sector. Whether you hold an NFZ card or pay for a private plan through PZU Zdrowie, Medicover, or LuxMed, a claim denial does not have to be the end of the road. Understanding your options is the first step toward getting the care — or reimbursement — you deserve.

How Health Insurance Works in Poland

Every employed person in Poland contributes to the Narodowy Fundusz Zdrowia (NFZ), the national health fund. NFZ covers a wide range of medical services at contracted public facilities, from primary care to specialist visits, hospitalisation, and prescription drugs. However, waiting times for specialists can stretch to months, which drives many Poles to purchase supplementary private health insurance.

Major private insurers operating in Poland include:

• PZU Zdrowie (part of the state-backed PZU Group — the largest insurer in Poland)
• Medicover (Swedish network with clinics and health plans)
• LuxMed (part of the Bupa group)
• Signal Iduna, Ergo Hestia, and Warta for supplementary plans

Common Reasons Claims Are Denied in Poland

Whether public or private, insurers rely on similar grounds for denial:

• Treatment not covered under your specific plan or NFZ entitlement
• Pre-authorisation not obtained before an elective procedure
• Service performed at a non-contracted facility (especially relevant for NFZ)
• Documentation incomplete — missing referrals, test results, or physician notes
• Condition classified as pre-existing for private plans
• Treatment deemed not medically necessary by the insurer's medical reviewer

Always request the denial in writing. Both NFZ and private insurers are required to provide a written explanation with the legal or contractual basis for the refusal.

Appealing an NFZ Claim Denial

NFZ decisions follow an administrative procedure governed by Polish health law.

Step 1 — Written objection (sprzeciw/odwołanie) Submit a formal written appeal to the Dyrektor Oddziału Wojewódzkiego NFZ — the director of your regional NFZ branch. The NFZ operates 16 regional branches (oddziały). Your denial letter will identify which branch issued the decision. You typically have 30 days from receiving the denial to file this objection. Include your patient card number, the specific service denied, supporting medical records, and a clear statement of why the denial was incorrect.

Step 2 — Administrative court (sąd administracyjny) If the regional director upholds the denial, you can challenge the decision before the Wojewódzki Sąd Administracyjny (WSA) — the regional administrative court. This step requires more preparation and, ideally, legal advice, but it is a legitimate and sometimes successful route for patients denied access to expensive or specialist treatments.

Tips for NFZ appeals:

• Get a referral (skierowanie) from your GP before specialist visits — many denials stem from skipped referrals
• Ask your treating physician to write a letter supporting medical necessity
• Keep all receipts if you had to pay out of pocket while appealing

Appealing a Private Insurance Claim Denial

For private plans, the process moves faster but involves different institutions.

Step 1 — Internal complaint (reklamacja) File a formal complaint directly with your insurer. Under Polish law, insurers must respond to complaints within 30 days (or 60 days for complex cases). Submit in writing by registered post and keep your proof of delivery.

Step 2 — Rzecznik Finansowy (Financial Ombudsman) If your insurer rejects your complaint or fails to respond in time, escalate to the Rzecznik Finansowy at rf.gov.pl. This is a free, government-backed institution that mediates insurance disputes. You can submit your complaint online or by post. The Rzecznik can request information from the insurer and issue a non-binding opinion — but most insurers settle at this stage to avoid further scrutiny.

Step 3 — Arbitration or court For disputes above a certain value, you can pursue binding arbitration through the Rzecznik's arbitration scheme or file a civil claim in the district court (sąd rejonowy). Legal aid (pomoc prawna) is available for those who cannot afford representation.

Practical Tips for All Policyholders

• Read your policy before you need it. Know which services require pre-authorisation and which facilities are in-network.
• File all complaints in writing. Phone calls are not legally binding records.
• Meet all deadlines. Missing the 30-day window for NFZ appeals can forfeit your right to challenge.
• Request your complete medical file from the treating facility to support your appeal.
• Contact a patient rights advocate — the Rzecznik Praw Pacjenta (Patient Rights Ombudsman) at rpp.gov.pl handles cases where patient rights have been violated alongside insurance issues.
