Brazilian courts are ordering private health insurers to apply the same regulated annual price cap used for individual and family plans to some small company contracts known as “false collectives.” The term refers to business health plans with only a few beneficiaries, often members of the same family.
The rulings affect a sensitive corner of Brazil’s private healthcare market. Collective plans, including company and association-based contracts, are not subject to the same annual price ceiling set by the National Supplementary Health Agency (ANS), Brazil’s regulator for private health insurance.
Why It Matters
Judges in first- and second-instance courts have annulled clauses that allowed increases based on claims ratios and medical-hospital cost variation, Folha de S.Paulo reported. In some cases, insurers have also been ordered to return amounts charged above the ANS cap.
The decisions generally cite precedents from Brazil’s Superior Court of Justice (STJ), the country’s top court for federal law, which allow small collective contracts to be treated exceptionally as individual or family plans when consumers have little bargaining power.
In May, STJ Justice Maria Isabel Gallotti rejected an insurer’s appeal and upheld a ruling that limited increases in a five-person collective contract to ANS rates for individual and family plans. According to Migalhas, the case involved successive claims-based increases totaling 72.39% from 2021 to 2023, allegedly without technical justification from the insurer.
The Regulatory Gap
ANS approved a maximum 5.1% increase for individual and family health plans on May 29. Those plans cover about 7.7 million people, or 14.5% of Brazil’s 52.9 million private health plan users, according to Folha.
Collective contracts remain outside that ceiling. Their increases are negotiated between insurers and contracting entities. In the first two months of 2026, collective-plan increases averaged 9.9%, Folha reported, citing ANS data.
Contracts with fewer than 30 beneficiaries have seen higher increases. In 2025, they rose by an average of 14.24%, compared with 9.62% for larger contracts. About one in four beneficiaries was tied to this type of contract in the first months of 2026.
Consumers and Insurers
Consumer lawyers say the courts are increasingly receptive to challenges against steep increases in these small contracts. Attorney Rafael Robba, from Vilhena Silva, told Folha that success rates in such cases have approached 90%.
One case cited by Folha involved Fernanda Vilaboim, a 59-year-old small business owner whose company plan covered three people: herself and two children. She said her monthly premium rose from R$1,900 to more than R$12,000 over eight years. A court ordered the retroactive use of ANS individual-plan rates for the last eight increases, cutting the premium to about R$6,000 and granting her restitution for overpayments.
Legal specialists caution that the issue is not settled nationally. Attorney Rosana Chiavassa told Folha that favorable rulings are case-specific, usually involving small family groups, and do not mean every family-run business plan qualifies as a false collective.
ANS says collective plans follow their own rules, actuarial calculations and market dynamics. It does not set a price ceiling for them and does not administratively recognize automatic equivalence with individual-plan increases.
Fenasaúde, the federation representing private health insurers, said there is no consolidated case law. The group argues that reclassifying these contracts disregards sector legislation and ANS rules that allow small and medium-size companies, including individual entrepreneurs, to buy collective plans without a minimum number of beneficiaries. It also warned that court intervention could raise prices and reduce plan availability for the broader market.
