A guide to applying on grounds of a deterioration: what counts as a deterioration, what medical and functional documentation is needed, when the right time to apply is, the difference between a deterioration at National Insurance and a repeat long-term care claim, and the mistakes that send an application back to the start.
In short: what counts as a deterioration?
A deterioration is a real change for the worse in the medical or functional condition since the previous decision. The key word is "since": the application is not an opportunity to argue that the previous decision was wrong, but to argue that reality has changed since then.
That distinction sinks many applications. A family that comes back with exactly the same documents, explaining again why the previous assessment was inaccurate, will usually get the same result. An application based on a deterioration has to point to what is new.
A deterioration can be an acute event — a hospital admission, a fracture, a stroke — or a gradual process, such as cognitive decline that has progressed or a loss of mobility that has worsened over months. Both kinds are legitimate, but both require documentation.
The documentation that makes an application serious
The basis of any deterioration application is a new, dated document created after the previous decision. An old document that was not submitted last time is not a deterioration — at most it is a gap being filled.
Pay attention to the wording: a medical summary setting out diagnoses alone explains less than one stating what the person can no longer do. If possible, it is worth asking the treating doctor to address the functional consequence explicitly and the help needed at home.
- An up-to-date medical summary from the treating doctor, after the previous decision
- Discharge summaries from hospital, A&E or rehabilitation
- A new cognitive assessment or diagnosis, where relevant
- Documents about new aids — walking frame, wheelchair, adjustable bed
- Documentation of increased help at home: a carer, extra hours, family presence
- A factual description of recurring incidents — falls, night-time confusion, leaving the house
When the right time to apply is
Applying too early, before the new documentation has accumulated, usually does harm: it produces another decision that changes nothing, and sometimes requires a further wait before you can apply again. Applying too late may miss deadlines or make it harder to prove when the change began.
The practical rule is to apply when you hold at least one new medical document describing the change, and a clear description of what has changed in the household routine. If a hospital stay has recently ended, it is worth waiting for the discharge summary and for the picture to settle after it.
Where fixed deadlines exist — such as a waiting period between applications or a deadline for lodging an appeal — check them in advance on the relevant body's website, because they change and they are not the same across routes.
A deterioration at National Insurance against a repeat long-term care claim
At National Insurance, an application based on a deterioration usually leads to a fresh assessment of the degree of dependency, and following it the entitlement level may change. The process is similar in structure to the first claim, but focuses on the change.
With an insurance company or a health fund the picture is different. There the question is not "has a deterioration occurred" but "is the definition in the policy now met". So someone recognised at a higher level by National Insurance may still not meet the insurance definition, and the reverse is also true.
A practical and important point: when a condition deteriorates, the date the deterioration began may affect the period for which a benefit is paid. So it is worth documenting the date the change began and not only the date the application was made.
Mistakes that send an application back to the start
Most applications that are refused are not refused because the condition did not deteriorate, but because the deterioration was not visible in the material. The following list gathers the recurring failures.
- Submitting the same documents that were submitted last time
- A general description along the lines of "the condition has deteriorated" with no examples or frequency
- Focusing on criticising the previous assessment instead of on the change that has occurred
- Attaching medical documents that do not bear on functioning
- Not stating the date the change began
- Missing a deadline for lodging an appeal or an objection
What Pele Yoetz does at this stage
The support focuses on understanding the previous decision, identifying the gap between what was recorded and what is actually happening, and organising the new material so that it presents the change factually and consistently.
The service does not constitute medical or legal advice, does not promise a change in the decision and does not determine entitlement. The binding document is the policy or the rules of the body handling the matter, according to the route.
Frequently asked questions
How long do you have to wait before applying on grounds of a deterioration?
Waiting periods between applications vary by route and by the body handling the matter. The precise rule has to be checked on the National Insurance website or with the insuring body before applying.
Can you apply on grounds of a deterioration even after a claim was refused outright?
Yes, where a real and documented change has occurred since the decision. A previous refusal does not block a new application based on a new condition, subject to the deadlines and the rules.
What has to appear in the medical document for it to be recognised as a deterioration?
The document should be dated after the previous decision, and should address not only the diagnosis but also the functional consequence — what the person cannot do and what help is needed.
Does a deterioration recognised by National Insurance bind the insurance company?
No. The insurance company assesses the claim against the definition in the policy. A National Insurance decision is a relevant document that can support the picture but does not decide it.
Does the date the deterioration began matter?
Yes, it may affect the period for which entitlement is assessed or a benefit paid. So it is important to document when the change began and not only when the application was made.
