Appealing a National Insurance decision —
what to do after a refusal

Received a refusal letter from the National Insurance Institute? Been given a disability percentage far lower than you expected? It is a frustrating and dispiriting feeling — but there is one thing you should know: a National Insurance decision is not the last word. Almost every decision carries a right of appeal, and in many cases it is the appeal stage that ends with a far better outcome.

Many people give up the moment they receive a refusal, feeling that “there is nothing to be done” or that the system is too strong. That is a costly mistake. In this article we explain exactly what an appeal is, what can be appealed, how long you have, and how to improve the chances of the appeal succeeding.

Let us be clear right away: a refusal or a low percentage does not necessarily reflect your real situation. It reflects what the first committee saw, on the basis of the documents and information before it at that moment. A missing document, an imprecise description of the difficulty, or an impairment that was never mentioned — any of these can lead to a decision that does not match reality. An appeal is exactly the opportunity to correct the picture.

What is an appeal, exactly?

An appeal is a request to re-examine a decision that has been made. Instead of accepting the decision as it stands, you ask that a further body — usually a more senior committee or a different forum — looks at the case again. An appeal is not just “another try”: it is a right anchored in law, and it exists precisely for situations in which the first decision does not reflect the true position.

It is important to understand: the appeal is heard afresh — you can add documents, expert opinions and records that were not before the first committee. Precisely for that reason, a well-prepared appeal can change the picture entirely.

Which decisions can be appealed?

Almost every National Insurance decision in the disability field can be appealed. Among the common cases:

• Refusal of a claim — a finding that you are not entitled at all.
• A low disability percentage — a percentage lower than the situation justifies.
• A low degree of incapacity — a finding that the impairment does not prevent you working, when in practice it does.
• Temporary disability instead of permanent — or the reverse.
• Withdrawal or reduction of an existing allowance — following a reassessment.
• Non-recognition of the connection between the injury and the event — for example in hostile-action or work-accident cases.

Timelines — how long do you have to appeal?

This is the most critical point. Every type of decision has its own filing deadline, and it is limited. In general:

• An appeal against a medical committee decision (disability percentages) is filed with a medical appeals committee — usually within a relatively short period from receipt of the decision.
• An appeal against a claims officer decision (refusal of a claim, degree of incapacity) is filed with the regional labour court — usually within a few months.

The exact deadlines vary by type of decision and are updated from time to time — which is why you must check the precise date given in the decision letter itself. Do not rely on an estimate: missing it by a day can cost you the right entirely. If the deadline is close, act immediately.

Where do you file? The different forums

The National Insurance appeal system is built in stages:

• A medical appeals committee — the forum that re-examines the medical disability percentages. It is a more senior panel, and you present the medical situation to it afresh.
• An incapacity appeals committee — re-examines the decision on the degree of incapacity for work.
• The regional labour court — the judicial forum, to which you turn on claims officer decisions, or on appeals committee decisions on a legal (rather than medical) question.

Each forum has its own rules about what can be argued and how. Understanding the right forum for your case is an important first step.

How do you file an appeal properly?

A good appeal is not just “filling in a form”. The main preparation stages:

• Understanding the reason for the refusal — reading the reasons for the decision carefully, so you know exactly what to challenge.
• Collecting further, up-to-date medical documentation — documents that were not before the first committee.
• A supporting medical opinion — in suitable cases, a specialist opinion can significantly strengthen the appeal.
• Reasoned drafting — a clear presentation of the reasons why the decision is wrong.
• Preparing for the hearing — if the appeal involves appearing before a committee, preparation is as critical as it was for the first one.

What should you attach to strengthen the appeal?

A strong appeal rests on evidence, not just on arguments. Here is what to attach where it is relevant to your case:

• Up-to-date medical records created after the original decision
• Hospitalisation summaries, new tests or treatments
• An opinion from a specialist in the field relevant to the injury
• Documentation showing deterioration or continuity of the condition over time
• Letters from treating professionals describing the actual functional impact

The more the file “speaks for itself” and is backed by documents, the less need there is to persuade — the facts do the work. Sometimes a single significant document that was not before the first committee is enough to change the whole picture.

What affects the success of an appeal?

The difference between an appeal that succeeds and one that fails usually lies in the preparation. The main factors:

• New and significant medical documentation that was not previously considered
• A professional opinion that sharpens the medical argument
• A precise account of the functional impact on daily life
• Identifying the weak points in the original decision
• Meeting the deadlines and the formal requirements

An appeal filed casually, with no substantive addition to the original claim, tends to fail. A well-founded, well-prepared appeal, by contrast, changes the outcome in many cases.

Another point worth knowing: the appeals committee usually consists of more senior doctors than those on the first committee, and sometimes from specialities more relevant to your case. So an appeal that presents the situation professionally and precisely — with the emphasis on the right medical field — can receive an entirely different assessment from the one you got at the first stage.

Common mistakes when filing an appeal

• Missing the filing deadline — the most critical and irreversible mistake of all
• Filing an appeal identical to the original claim, with no new documentation or argument
• Not understanding the reason for the refusal, and therefore attacking the wrong point
• Arriving at the appeals committee without proper preparation
• Giving up after the first appeal is refused, without considering the next forum

Is it really worth appealing?

A question many people ask themselves after a refusal: “maybe I just have no chance?”. The honest answer is that no outcome can be guaranteed — but it is worth knowing that a substantial proportion of appeals do end with an improved outcome, whether through a higher disability percentage, recognition of a claim that was refused, or a change in the degree of incapacity. That is especially so when you have new documentation, or where the first decision did not properly address all the impairments.

On the other hand, if the first decision faithfully reflected your situation and you have no new information or documentation, the chances may be lower. The right approach is to look at the case on its merits: read the reasons for refusal carefully, check which documents can be added, and assess honestly whether there is a basis for improvement. In many cases, a professional review of the decision reveals gaps that can be challenged.

How long does it take and what should you expect?

The appeal process may take several weeks to several months, depending on the caseload and the forum. It is important to be patient and to follow the progress. During that period you may be asked to complete documents or to attend a hearing — preparing in advance will save delays and avoid unnecessary postponements.

When is professional support worthwhile?

You can file an appeal yourself — but in complex cases, professional support can make the difference. Especially when it comes to collecting documentation, drafting the arguments, choosing the right forum and preparing for the hearing. The right support improves the chances of success and takes a large part of the burden and the stress off you.

It is particularly worth considering support where the appeal concerns a decision you have already appealed once, where the case involves several different impairments that combine with one another, or where the refusal was reasoned on complex medical grounds. In those situations, knowledge and experience of dealing with the system can be the difference between an appeal that is refused again and one that succeeds.

A first refusal is not a final answer — it is an invitation to a well-prepared appeal. In many cases, that is exactly where the outcome turns around.

In summary

If you have received a refusal or a low percentage from the National Insurance Institute, do not give up. The right of appeal exists precisely for these moments. The most important thing is to act in time — check the filing deadline immediately, collect supporting documentation, and file a well-founded, reasoned appeal. With the right preparation the chances of success rise significantly, and many people who got a “no” at the start found themselves receiving what they were entitled to in the end.
