Failure to cover costs This is a situation in which the insurer does not cover all or part of the medical treatment costs despite a claim being filed or a request for reimbursement. Most often, this is due to policy limits, exclusions, treatment outside the scope of coverage, or procedural deficiencies in the documentation. In this article, we explain what to do when health insurance does not cover medical costs, how to determine the basis for the denial, and how to safely navigate the claims process or a policy change.
What is a lack of coverage for medical expenses?
A lack of coverage for medical expenses means that the policy does not cover a given medical service, either in full or in part. In practice, this may apply to doctor’s visits, tests, hospital stays, the purchase of medications, or surgeries. For a foreigner in Poland, this problem can be particularly stressful, as it affects not only their health but also their stay, budget, and administrative procedures.
An analysis of policy terms and conditions shows that insurers most often refuse to pay when treatment falls outside the scope of coverage, relates to a pre-existing condition, was performed outside the insurance period, or involves costs excluded in the General Terms and Conditions. Expenses for rehabilitative treatment, stays at a health resort, preventive dental care, or expenses not directly related to necessary treatment are also often not covered. Therefore, before filing a claim, it is a good idea to compare the bill with the policy provisions and the general terms and conditions.

💡 Tip
First, ask the insurer for a written explanation of the denial. Without it, it will be difficult to file a complaint or appeal effectively.
Why is the insurer refusing to pay?
When insurance does not cover the costs, the reason usually lies in the General Terms and Conditions or in the way the claim was filed. In policies for foreign nationals, exclusions are common for treatment that began before coverage took effect, chronic illnesses without an extension of coverage, physical labor without an additional premium, high-risk sports, and costs incurred outside the policy’s territorial scope. Financial limits and the requirement to contact the assistance center in advance can also be problematic.
Some products reimburse only medically necessary costs incurred within Poland. Some policies do not cover preventive care, cosmetic surgery, stays at health resorts, special diets, or medications already covered by the National Health Fund (NFZ). It also happens that the insurer requests documentation confirming which portion of the costs was paid by the patient and which by the public health system. This is an important consideration when insurance cost issues arise.
Formal errors are another reason for denial. The lack of translated documents, a missing itemized invoice, no proof of payment, or filing a claim too late can delay a decision or result in a denial.

What are the step-by-step instructions?
If you’re wondering what to do when your claim is denied, start by gathering all your documents. You’ll need your insurance policy, the General Terms and Conditions, the denial notice, the treatment information sheet, prescriptions, referrals, invoices, and payment confirmations. Next, compare the name of the service with the scope of coverage. Check whether the denial is due to an exclusion, a limit, a waiting period, territorial coverage, or an error in the procedure.
The next step is to file a complaint. Briefly describe the nature of the issue, the amount that was not covered, and why you believe the decision was incorrect. It’s a good idea to cite specific provisions of the General Terms and Conditions, provide medical documentation, and include proof of payment. If the treatment was an emergency, also describe the circumstances and explain why it was not possible to obtain prior approval from the assistance provider. Submit your claim in writing or via the official form to maintain a record of the case.
If the answer is still no, ask for a reconsideration of your case, seek assistance from the Financial Ombudsman, or compare the policy with other options available to foreign nationals. In some situations, it’s also worth checking whether it’s possible to changes of insurance during the stay.
What documents to prepare?
It's best to prepare all the documents at once, because missing even one attachment can delay the process. Insurers usually expect the documents to be in your name and legible.
💡 Important
Don't rely solely on the product name. Whether a claim is paid depends on the limits, coverage definitions, and exclusions set forth in the General Terms and Conditions.
How can you reduce the risk of problems?
The best protection against a dispute is a good insurance policy tailored to your actual situation. A foreigner doing manual labor, a student, or someone planning a longer stay will need different coverage. Before purchasing a policy, check the coverage limit, outpatient treatment, hospitalization, chronic conditions, medication coverage, assistance services, and the requirements for a visa or residence permit. It will be helpful to compare this with the article on private insurance rankings.
It’s also a good idea to find out in advance how the medical hotline works and when you need to report your treatment before your appointment. In many policies, hospitalization arranged through the emergency call center is easier to claim than services you pay for on your own. If your residency status changes, be sure to also read the guide on Changing Insurance During Your Stay.
When you repeatedly encounter cost issues with insurance, it’s worth analyzing not only the premium price but also the practical scope of coverage. A cheaper policy may have more limits and exclusions, which can end up being much more expensive when you need medical treatment.
Frequently asked questions
What does it mean when insurance does not cover medical expenses?
This means that the insurer refuses to pay for a particular service or reimburses only a portion of the expenses. This may be due to policy limits, exclusions, missing documentation, or treatment that is not covered.
What should I do if my refund request was denied?
First, ask for a full written explanation of the decision. Then, compare the denial with the General Terms and Conditions, gather your medical records, and file a complaint with specific arguments and receipts.
What costs are most often not covered?
Costs for treatment that began before the policy was issued, rehabilitative treatment, preventive dental care, stays at a health resort, special diets, or certain medications are often excluded. Much depends on the specific policy and the sum insured.
Can I appeal the insurer's decision?
Yes, in most cases, you can file a complaint or request a reconsideration of the matter. If that doesn't help, you can seek assistance from the Financial Ombudsman or legal advice.
What documents are required to file a complaint?
You will usually need your insurance policy, the general terms and conditions, a denial notice, medical records, personalized invoices, and payment confirmations. If the matter concerns your stay and legalization, it’s also a good idea to keep documents related to the purpose of your stay and the scope of the required insurance.
Is it worth switching insurance policies after having problems with coverage?
Yes, if your current plan no longer meets your needs. Before switching, check the coverage for hospitalization, outpatient care, chronic conditions, and assistance, as well as the guide on unemployment insurance options, if this applies to your situation.
Summary
When your insurance doesn’t cover medical expenses, it’s best not to react emotionally. First, determine the basis for the denial, review the General Terms and Conditions, and gather all the necessary documentation. Then file a claim and assess whether the problem stems from a one-time error or from coverage that’s too limited. If you want to avoid similar situations in the future, compare the options available to foreigners and choose a policy tailored to your actual health and residency needs.
