Permanent disability refused by the INSS: prior claim, lawsuit and the medical evidence that counts

If the INSS (the National Social Security Institute) has refused you a permanent disability pension, or granted a lower degree than the one you applied for, it is not the end of the road: the decision can be challenged. But the deadlines are short and the outcome depends above all on the medical and employment evidence you provide. We explain how to challenge it, which evidence carries weight and what to expect from the hearing, under the rules in force in October 2026.

What the INSS has decided and why

The INSS Provincial Directorate decides on the basis of the proposed opinion of the Disability Assessment Team (EVI), which relies on the medical summary report prepared by INSS doctors and on the report on your work history. It has a maximum of 135 days to decide; if it does not, the application is treated as refused by silence and you can still claim.

The degree depends on how your sequelae affect your usual occupation (art. 194 of the General Social Security Act, LGSS, and transitional provision 26, which keeps the classic definition of the degrees):

Since 1 May 2025 the former «gran invalidez» is called gran incapacidad (Act 2/2025).

There are three usual grounds for a refusal. Identify yours in the decision, because it sets the strategy:

• You do not reach the degree: the INSS considers your limitations are not serious enough for your occupation.
• The injuries are not definitive: the law requires serious anatomical or functional reductions that can be objectively determined and are expected to be permanent after the prescribed treatment (art. 193 LGSS). A recovery that is uncertain or long-term does not prevent a finding of disability. Since November 2024 (Act 3/2024), prior treatment may not be required in irreversible conditions where the reductions are sufficiently objectified.
• Affiliation or contribution requirements are missing: for common illness a minimum contribution period that depends on your age is required; for an accident, whether work-related or not, and for occupational illness, it is not (art. 195 LGSS).

Deadlines: prior claim and lawsuit

Before going to court you must file a prior claim (reclamación previa) with the INSS (art. 71 of the Social Jurisdiction Act, LRJS). The deadlines are:

In the court phase, August and the days from 24 December to 6 January are non-working days for this type of case (art. 43 LRJS), but the exact count should be set by a lawyer and it is unwise to rely on that margin. If you miss the deadline, the law allows the prior claim to be repeated while the right has not become time-barred, but you may lose the retroactive effect of the pension (art. 71.4 LRJS).

Two practical points. First, at the hearing facts other than those alleged in the administrative file cannot be raised, except new facts or facts that could not previously be known (arts. 72 and 143.4 LRJS): in the prior claim it is advisable to list all your conditions, provide the reports already and put forward the degree you consider correct. Second, as a worker or Social Security beneficiary you have the right to free legal aid in the social jurisdiction (art. 2.d of Act 1/1996), and requesting a duty lawyer suspends the limitation deadlines (art. 21.4 LRJS). At first instance a lawyer is optional; in an appeal (recurso de suplicación) it is compulsory.

Which medical evidence counts

The judge does not assess your diagnosis, but what you cannot do and why. What usually weighs most:

1. Reports from your specialists, recent, with diagnosis, progress, treatment and, above all, specific functional limitations: how much weight you can lift, how long you can stand or sit, whether you can concentrate, whether you need breaks.
2. Objective tests according to your condition: MRI scans, electromyography, respiratory or cardiac function tests, neuropsychological studies, validated clinical scales in mental health.
3. Treatment history and its results: medication, rehabilitation, surgery, hospital admissions. It shows that treatment has been exhausted or that improvement is uncertain.
4. Sick-leave history: duration and relapses during temporary incapacity.
5. A medical expert report commissioned by you, which the expert confirms at the hearing (art. 93.1 LRJS). The judge may also call in a forensic doctor (art. 93.2).

Generic reports, without objective tests, without specific limitations or well before the date of the decision usually weigh less.

Your usual occupation: where the degree is decided

The same clinical picture can lead to different degrees depending on the job. A shoulder injury may prevent a bricklayer from doing the core tasks of the trade and still be compatible with an office post. That is why the law looks at the occupation you performed at the time of the accident or, in illness, your main activity during the prior period set by regulation. Document:

• The real tasks of your post and their physical and mental demands: effort, postures, shifts, customer contact, driving, responsibility.
• Your job category and contract, your employment record and, if possible, a report from the company or the risk assessment of the post.

From total to absolute. Total covers your occupation; absolute requires that you cannot do any job. Courts tend to assess whether, with your limitations, you could carry out any activity, even a sedentary one, with regularity and reasonable output. That is why absolute disability is usually argued where there are several conditions combined, chronic pain or cognitive or psychiatric impairment that affects any occupation, and everything depends on the evidence. The difference matters: total is compatible with working in a different activity (art. 198.1 LGSS); absolute only allows activities compatible with your condition (art. 198.2). If your case involves long covid, there are divergent court approaches, which we explain in permanent disability for post-covid syndrome.

What the hearing is like and how long it takes

On admitting the lawsuit, the court requests the file from the INSS (ten days to send it) and sets the hearing. At the hearing the documentary and expert evidence is heard and the judge gives judgment. We cannot give you a reliable timescale: it depends on the court's workload and on whether a forensic doctor's report is requested. Expect several months between the lawsuit and the judgment, and sometimes more than a year.

The judgment may recognise the degree, set the date from which you are paid and the amount, or uphold the refusal. In both cases a recurso de suplicación lies to the High Court of Justice (Tribunal Superior de Justicia) in proceedings on the recognition or refusal of benefits and on the applicable degree (art. 191.3 LRJS). It must be announced within five days of notification (art. 194 LRJS) and the INSS can appeal too.

If you are still on sick leave, read what happens after 18 months of sick leave. And if you already have a degree recognised and fear a review, see the review of permanent disability at 24 months.

Is it worth appealing?

It depends on three questions: whether your clinical picture is objectively documented and shows functional limitations, whether it fits the real demands of your occupation, and whether you meet the affiliation and contribution requirements. Some refusals are overturned in court and others are upheld: nobody can assure you of the outcome. This is what you can do now:

1. Read the decision: note the date of notification and the ground.
2. Ask for a copy of your file, with the proposed opinion and the medical summary report.
3. Update your reports and document your job.
4. File the prior claim within the deadline and keep the receipt.
5. If the INSS rejects it or does not reply, file the lawsuit within 30 days.

If you want to know whether your case has prospects, we can review the decision and your reports and tell you which deadlines are running and what evidence is missing: you can book a consultation on permanent disability.
