Artificial intelligence is already being used to screen INSS applications. It speeds up reviews, but it also produces automatic denials that can hurt insured workers who are not paying attention.

How Artificial Intelligence Works in INSS Screening

In recent years, the National Social Security Institute has begun incorporating artificial intelligence tools into its internal process for reviewing applications. This change did not happen in isolation. It is part of a broader movement to digitize Brazilian public services, one that gained momentum after the COVID-19 pandemic, when the government needed to keep serving the public despite restrictions on in-person visits. When we talk about automated screening, we mean the use of algorithms that check registration data, cross-reference information from different government databases, and apply predefined criteria to classify the applications the agency receives.

In practice, when an insured person files an application for retirement, sickness benefits, or any other social security benefit through the Meu INSS portal, that application goes through layers of automated checks before it ever reaches a human claims examiner. The system cross-checks data from the Cadastro Nacional de Informações Sociais (CNIS, the National Social Information Registry), verifies employment relationships, confirms contribution periods, and flags possible inconsistencies. This preliminary analysis allows applications with complete documentation and clearly met requirements to be processed more quickly, while those with problems are sent to a more detailed manual review.

We have observed that this automation has brought real efficiency gains to the INSS, which has historically struggled with case backlogs and long waiting times. However, the same technology that speeds up legitimate benefits can also produce premature denials when the algorithm cannot correctly interpret more complex situations, such as periods of special (hazardous) work activity, rural work without formal registration, or late contributions.

The Risks of Automated Denials for Insured Workers

One of the most worrying aspects of AI screening at the INSS is the possibility of denials based solely on algorithmic criteria, without proper human review of the details of each case. Many insured workers receive automatically generated administrative denials with generic explanations that do not reflect the real complexity of their social security situation. This happens because algorithms work with patterns and rigid rules, while Social Security Law is a field full of exceptions, transition rules, and factual circumstances that call for interpretation in context.

Consider, for example, a worker who spent part of his career in unhealthy or hazardous conditions. The automated system may fail to recognize his right to convert special-activity time into ordinary contribution time if the Perfil Profissiográfico Previdenciário (PPP, the Social Security Occupational Profile) is not electronically linked to the CNIS. Likewise, rural workers who contributed under a family-farming arrangement often run into difficulties, because their activities do not always appear in the electronic databases that feed the screening algorithm.

Another sensitive point involves disability benefit applications. Although the medical examination still depends on an in-person or telemedicine evaluation, the initial screening of the application can block a request before an exam is even scheduled if the system detects registration inconsistencies or missing documents. In those cases, the insured person who needs the benefit most (precisely because he or she cannot work) ends up facing additional bureaucratic obstacles created by the very automation that was supposed to make access to the benefit easier.

Automation at the INSS speeds up processing, but it should never replace qualified human review in situations involving the fundamental rights of insured persons.

We have also found that the technical language used in automatic denial notices makes them hard for insured persons to understand. Many do not know exactly why they were denied and, as a result, do not know what steps to take to reverse the decision. This lack of algorithmic transparency is a problem that goes beyond social security and affects any public agency that adopts artificial intelligence tools without proper accountability mechanisms.

The Right to Human Review and the Insured Person’s Defenses

Given this scenario, insured persons need to know their rights when they receive an administrative decision generated (wholly or in part) by automated systems. Brazilian law guarantees the right to be heard and to a full defense in administrative proceedings, as provided in the Federal Constitution. This means that no decision affecting individual rights can be made final unless the person concerned has had the chance to respond and submit additional documents. See also our firm’s content on MLOps and AI Models in Production at the INSS.

Within the INSS, an insured person who receives a denial has the right to file an administrative appeal with the Conselho de Recursos da Previdência Social (CRPS, the Social Security Appeals Council), where human adjudicators will reexamine the matter. The appeal must be filed within 30 days of the date you are notified of the decision, and you do not need to hire a lawyer (although specialized legal advice is strongly recommended to improve your chances of success). Besides the administrative appeal, the insured person can go to court by filing suit in the Federal Special Courts (for claims of up to 60 minimum monthly wages) or in the regular Federal Courts.

We believe the most effective strategy for an insured person who wants to challenge an automated decision starts with a close review of the CNIS statement and the denial letter. You need to identify exactly which periods or requirements the system did not recognize and gather the supporting evidence. Work booklets, employment contracts, contribution payment slips, technical reports, employer statements, and other documents can be decisive in proving the right that the algorithm could not verify automatically.

We also stress the importance of requesting an administrative review, which can be done directly through the Meu INSS portal or in person at an INSS office. In many cases, simply submitting additional documents that were not in the system is enough to overturn the denial without an appeal or a lawsuit. This possibility reinforces the idea that automated screening, while useful as an initial filter, cannot be treated as a final decision that admits no challenge.

Algorithmic Transparency and the Future of Digital Social Security

The debate over the use of artificial intelligence in Brazil’s social security system is not limited to operational efficiency. It involves fundamental questions of transparency, fairness, and the protection of rights. When an algorithm decides (or helps decide) whether a citizen will receive a social security benefit, the issue directly affects the dignity and survival of people in vulnerable situations. For that reason, we argue that these technologies should be implemented together with robust transparency and oversight mechanisms.

The Lei Geral de Proteção de Dados (LGPD, Brazil’s General Data Protection Law) provides that data subjects have the right to request review of decisions made solely on the basis of automated processing of personal data. Although applying the LGPD directly to the INSS raises debates about the legal basis available to public authorities, the principle of algorithmic transparency is a guiding standard that should shape the agency’s conduct. Insured persons have the right to know what criteria were used to analyze their application and how the system reached its conclusion. For more information, read our firm’s article on Automated Decision Algorithms in INSS Benefits.

We note that other countries that have adopted similar systems have faced comparable problems. International experience shows that automating social security decisions requires specific safeguards, such as periodic algorithm audits, mechanisms for explaining decisions, and accessible channels for challenging them. In Brazil, the use of artificial intelligence at the INSS is expected to grow in the coming years, in line with the global trend of digitizing public services. That makes the debate over the necessary limits and safeguards to protect insured persons’ rights even more urgent.

We believe technology should serve as a tool of inclusion, not as an additional barrier to accessing rights. Automated screening can be extremely beneficial when it is used to speed up benefits for people who clearly meet the requirements, freeing INSS staff to give qualified attention to the more complex cases. The problem arises when automation is used to cut costs at the expense of the quality of review and respect for insured persons’ procedural guarantees.

How to Prepare an Application in an Automated Environment

Given the reality of automated screening, we have put together some practical guidance to help insured persons improve their chances of having a benefit granted correctly on the first review. The first step is to check and update your CNIS before you file the application. You can access this statement through the Meu INSS portal or app, and it lists all the employment relationships and contributions recorded in the system. Any discrepancy or missing period should be corrected beforehand by submitting supporting documentation at an INSS office.

We also recommend that you organize all relevant documentation in digital form before starting the online application. That means scanning documents in a legible format (preferably PDF), naming the files clearly, and checking that every contribution period is properly backed up by supporting records. The more complete and organized the documentation you submit with the application, the less likely it is that the automated system will flag problems that could lead to a denial or to requests for additional documents.

For workers with periods of special activity, it is essential to get an updated PPP from the employer (or former employer) before filing the application. This document is critical for recognition of special time, and its absence when the application is filed is one of the most frequent causes of automated denials in applications for special retirement or for conversion of special-activity time.

Finally, we consider it prudent for insured persons to seek specialized legal advice before filing more complex applications, such as retirements under transition rules, benefits involving rural work periods or concurrent activities, and requests to review benefits that have already been granted. A qualified professional can review your situation in advance, identify potential weak points, and prepare the application in a way that minimizes the risk of an automated denial. This advance preparation saves time, avoids frustration, and significantly improves your chances of success in the administrative process.
