NFZ Health Insurance Claim Denied in Poland

The Narodowy Fundusz Zdrowia (NFZ) is Poland's mandatory public health insurer, covering virtually the entire employed population. When the NFZ refuses to reimburse a treatment or denies access to a covered service, patients have a clear legal right to challenge that decision. This guide walks you through the NFZ appeal process step by step.

What NFZ Covers — and What It Often Refuses

NFZ covers a broad range of services at contracted public facilities: GP visits, specialist consultations, hospitalisation, surgery, maternity care, and many prescription drugs under the national reimbursement list (lista leków refundowanych). However, denials are common for several reasons:

• Non-contracted facility: You visited a clinic or hospital that does not have an agreement with the NFZ, or your NFZ branch did not pre-approve out-of-network care
• Missing referral (skierowanie): Many specialist visits and diagnostic tests require a GP referral; without one, NFZ will not reimburse the cost
• Service outside the benefit package: Some treatments — including many dental procedures, cosmetic interventions, and experimental therapies — fall outside standard NFZ coverage
• Administrative errors: Incorrect PESEL number, wrong billing codes submitted by the facility, or missing documentation from the provider
• Capacity decisions: NFZ queues are limited; you may be told a service is available but not for months, which effectively becomes a functional denial

The NFZ Appeal Process

Step 1: Understand the Denial

Request the denial in writing if you have not already received one. The denial letter must state:

• The specific service or reimbursement refused
• The legal or regulatory basis for the refusal
• The deadline and procedure for appealing

If your treating facility received the denial on your behalf, ask them for a copy of the full decision document.

Step 2: File a Written Objection with the Regional NFZ Director

Submit a formal written objection (odwołanie or sprzeciw, depending on the type of decision) to the Dyrektor Oddziału Wojewódzkiego NFZ — the director of the regional NFZ branch in your voivodeship. Poland has 16 voivodeships, each with its own NFZ branch.

Deadline: You generally have 30 days from the date you received the written denial to file your objection. Do not miss this window — late appeals may be dismissed on procedural grounds alone.

What to include in your objection:

• Your full name, PESEL number, and NFZ policy number
• A clear description of the service denied and the date of the original decision
• The specific grounds for your appeal — for example, that the service is medically necessary, that a referral was in fact provided, or that the facility is legitimately contracted
• Copies of supporting documents: the treating physician's letter, referral, test results, hospital discharge summary, and any receipts if you paid out of pocket
• A specific request — reimbursement, approval of the service, or reversal of the decision

Send your objection by registered post (list polecony) and keep the proof of sending. You can also deliver it in person to the regional NFZ office and request a receipt stamped with the date.

Step 3: NFZ Regional Review

The regional NFZ director must review your objection and issue a written decision. The review typically takes 30 to 60 days. The director may uphold the original denial, partially grant your appeal, or fully reverse the decision.

Step 4: Appeal to Administrative Court

If the regional director upholds the denial, you can escalate to the Wojewódzki Sąd Administracyjny (WSA) — the Regional Administrative Court. You must file within 30 days of receiving the regional director's decision.

At this stage, consider engaging a lawyer specialising in administrative law or health law. Legal aid (pomoc prawna z urzędu) is available if you meet income criteria. The administrative court reviews whether the NFZ decision was lawful — it does not re-examine clinical facts but assesses whether procedure was followed correctly and whether the law was applied properly.

If the WSA rules in your favour, the case is returned to NFZ for a new decision in line with the court's findings.

Special Situations

Urgent or emergency care: If your denial relates to emergency treatment you already received at a non-contracted facility because no NFZ facility was available, NFZ is generally obligated to reimburse reasonable costs. Document the circumstances carefully — including any failed attempts to access an NFZ facility at the time.

Cross-border care (EU): If you were treated in another EU country, you may be entitled to reimbursement under EU coordination rules or the Patients' Rights Directive. NFZ has a dedicated department for cross-border care claims.

Rare diseases and expensive therapies: For denials involving specialised drug programmes or rare-disease treatments, the Rzecznik Praw Pacjenta (Patient Rights Ombudsman) at rpp.gov.pl can intervene on your behalf.
