Age-Based Premium Increases and STJ Topic 952

A health plan may charge more when a member moves into a new age bracket, but Brazil’s Superior Court of Justice has set three cumulative requirements for that increase to be valid. Outside those requirements, the clause is abusive and the amount overpaid can be refunded.

Two Different Increases Within the Same Contract

The monthly premium of an individual or family health plan goes up for two legally distinct reasons. The first is the annual adjustment, which tracks changes in the cost of care and, for individual plans, follows a maximum percentage published by Brazil’s National Supplementary Health Agency (ANS). The second is the age-bracket increase, which applies when the member reaches the age that starts a new bracket set out in the contract.

Confusing the two leads to a wrong diagnosis. The annual adjustment affects the plan’s entire pool of members; the age-based increase reaches only those who changed brackets that month. A bill that nearly doubles from one month to the next is rarely explained by the annual adjustment. It almost always comes from the age-bracket table attached to the contract.

The legal basis for the age-based increase is Art. 15 of Law 9.656/1998. That provision allows the premium to vary according to the consumer’s age, but only if the original contract already states the age brackets and the percentage increase that applies to each, in accordance with the rules issued by ANS. A generic clause that announces an age-based increase without saying when and by how much does not meet that standard.

The practical consequence is immediate. Before debating whether the percentage is too high, check whether it was written down. A contract that does not show the bracket table in the signed document is flawed on this point from the start, because the member had no way of foreseeing the jump that would hit years later.

The Three Requirements of Topic 952 of the STJ (Brazil’s Superior Court of Justice)

The issue was submitted to the repetitive-appeals regime and decided as Topic 952 (STJ REsp 1.568.244/RJ). The question before the court was precisely whether a health plan clause that raises the monthly premium when the member changes age brackets is valid. The thesis the court adopted neither banned age-based increases nor approved them outright: it set conditions.

Under the thesis, a premium increase in an individual or family health plan based on the member’s change of age bracket is valid as long as three elements are present together:

1. the contract provides for the increase and for the brackets to which it applies;
2. the rules issued by the government regulatory bodies are observed;
3. there are no unreasonable or arbitrary percentages that, in the specific case and without a sound actuarial basis, place an excessive burden on the consumer or discriminate against older persons.

The key to reading the thesis is that the requirements are cumulative. A percentage that fits within the regulator’s limits can still be invalidated if it proves unreasonable in the specific case. By the same logic, a modest increase cannot be saved when the clause authorizing it was not in the signed contract.

The third requirement shifts the burden of argument to the operator. Requiring a sound actuarial basis means demanding that the price jump correspond to a demonstrable risk calculation, rather than to a number chosen to push older members out of the plan.

A percentage within the regulator’s limit is still invalid if, in the specific case, it is unreasonable and lacks a sound actuarial basis.

This reading explains why disputes over similar contracts can end differently. The review under the third requirement is case-specific, depends on evidence, and compares the challenged percentage with the other percentages in the same contracted table. The thesis covers individual or family plans; group contracts follow their own pricing logic and were not the subject of this repetitive-appeals ruling.

Which Industry Rule Governs Each Contract

The second requirement points to the industry’s regulations, and the applicable rule depends on the date the contract was signed or adapted. In deciding Topic 952, the Superior Court of Justice separated contracts into three generations, each with its own standard of review.

For old contracts, signed before Law 9.656/1998 took effect and never adapted, the terms of the contract itself control. Consumer protection law still applies to the abusiveness of the increase percentages, and the guidelines of ANS Normative Summary (Súmula Normativa) 3/2001 apply to the formal validity of the clause.

For contracts signed or adapted between January 2, 1999 and December 31, 2003, the rules of CONSU Resolution 6/1998 (issued by Brazil’s Supplementary Health Council) apply. They require seven age brackets and a cap on the variation between the first and the last: the increase for members over seventy cannot exceed six times the amount set for members between zero and seventeen.

This same generation carries an additional protection. The premium cannot vary for an older member who has been enrolled in the health plan or insurance for more than ten years, a criterion that echoes the sole paragraph of Art. 15 of Law 9.656/1998.

For contracts signed on or after January 1, 2004, the rules of ANS Normative Resolution 63/2003 apply. They require ten age brackets, with the last one starting at age fifty-nine, and provide that the price of the last bracket cannot exceed six times the price of the first.

The same resolution contains a second safeguard, less well known and quite useful in practice: the cumulative variation between the seventh and tenth brackets cannot exceed the cumulative variation between the first and seventh. In other words, the operator cannot concentrate the weight of the increases in the oldest ages.

You can check this safeguard with the contract’s table and a calculator. Add up the variations of the initial brackets and of the final brackets, then compare the two blocks. A table that fails this test violates the industry rule and, as a result, stumbles on the second requirement of the thesis.

At Age Sixty, Age-Based Increases Stop

The Statute of Older Persons (Estatuto da Pessoa Idosa), enacted by Law 10.741/2003, governs the rights guaranteed to people aged sixty or older, under its Art. 1. And Art. 15, § 3, is categorical: discrimination against older persons in health plans through the charging of different amounts because of age is prohibited.

This prohibition fits the regulator’s table precisely. If the last permitted age bracket begins at age fifty-nine, the last legally possible age-based increase occurs at that age. Once a member turns sixty, there is no new bracket to enter and no new percentage to charge because of a birthday.

The protection in Law 9.656/1998 was narrower. The sole paragraph of its Art. 15 bars age-based variation for consumers aged sixty who have been in the plan, or whose predecessors have been in it, for more than ten years. The Statute dropped that length-of-membership requirement and protects older persons by virtue of their age, regardless of when they joined the plan.

There is also a relevant timing issue. The Statute was enacted in 2003 and took effect ninety days after publication, under its Art. 118. Whether it applies to a health plan contract signed before it took effect is an issue of general repercussion before Brazil’s Supreme Federal Court, under Topic 381, a link the Superior Court of Justice itself noted when addressing Topic 952.

The ban on age-based increases should be distinguished from exposure to the annual adjustment. Older persons are still subject to the annual cost adjustment, which applies to the entire pool of members and has nothing to do with birthdays. What the Statute prohibits is a different price because of age.

How to Respond to a Disproportionate Increase

The first step is documentary, not judicial. The member should gather the signed contract with its age-bracket table, the bills for the last twelve months, and the notice that announced the increase. Without these three documents, any assessment of whether the percentage is valid remains guesswork.

The next step is to ask the operator, in writing and with a protocol number, for the calculation behind the increase applied and for the actuarial basis that supports it. The response, or the lack of one, has evidentiary value: an operator that does not show its calculation weakens its position on the third requirement of the thesis.

With the documents in hand, comes the arithmetic test. Once you identify the date of signing, you determine the applicable rule; once you identify the rule, you check its limits, that is, the number of brackets, the ratio between the last and the first, and the comparison between the cumulative blocks.

Administrative channels work and cost little. The National Supplementary Health Agency accepts complaints from members and can investigate violations of the industry rule; consumer protection agencies address the abusiveness of the clause. Neither channel prevents you from filing a lawsuit later.

In court, the typical request combines review of the increase clause, recalculation of the monthly premium, and a refund of the amounts overpaid. Where there is a concrete risk of losing the plan, you can request urgent relief to suspend the increase and keep the member in the plan while the percentage is being disputed.

One practical precaution matters more than it seems: disputing the increase does not allow you to stop paying. The sole paragraph of Art. 13 of Law 9.656/1998 prohibits the operator from unilaterally terminating an individual contract, except in cases of fraud or nonpayment of the monthly premium for more than sixty days, consecutive or not, within the last twelve months of coverage, provided the consumer is proven to have been notified by the fiftieth day of default.

Read in reverse, that provision shows how big the risk is. A member who stops paying to protest the increase can lose the plan and, along with it, the waiting periods already served. The safe path combines three simple acts: pay, formally record your disagreement, and demand a refund of the excess.

Frequently Asked Questions

Can the plan raise the monthly premium just because the member had a birthday?

It can, as long as the birthday moves the member into a new age bracket provided for in the contract and the three requirements of Topic 952 are met. A birthday within the same bracket does not trigger an age-based increase. And from age sixty on, charging a different amount because of age is expressly prohibited by Art. 15, § 3, of the Statute of Older Persons.

How can I tell whether the percentage applied is unreasonable?

The assessment is comparative and is made on the contracted table itself. In contracts signed on or after January 1, 2004, the price of the last bracket cannot exceed six times that of the first, and the cumulative variation between the seventh and tenth brackets cannot exceed the cumulative variation between the first and seventh. A percentage that breaks these limits violates the industry rule.

Does the age-bracket increase replace the annual adjustment?

No. They are separate increases with different causes, and both can apply in the same year. The annual adjustment tracks changes in the cost of care and reaches the entire pool of members; the age-bracket increase results from a change in age and affects only those who moved to a new bracket. The Statute of Older Persons’ prohibition applies to the second, not the first.
