Coverage denials by health plan providers are among the most common complaints from consumers in Brazil, and many of them have no legal basis. Waiting periods, claims of a preexisting condition, and treatments missing from the regulatory agency’s list are the three most common arguments, but legislation and case law set strict limits on each one.

What the Law Says About the Relationship Between Consumers and Providers

Health plans in Brazil are governed by Law 9.656/1998 and overseen by the Agência Nacional de Saúde Suplementar (Brazil’s National Supplementary Health Agency). The Consumer Protection Code also applies on top of this framework, under the settled position of the higher courts, which recognize the plan member as the vulnerable party to the contract.

This dual protection has a direct practical consequence: clauses that restrict rights excessively can be declared abusive, and unclear points in the contract must be interpreted in the consumer’s favor. The provider, for its part, has a duty to state clearly what is covered and what is excluded.

When a denial arrives, usually in writing or by phone, plan members tend to accept it as final. That is the first mistake. An administrative refusal does not close the discussion, and the record of court decisions shows that many denials are later reversed.

Waiting Periods: What the Provider Can and Cannot Demand

A waiting period (carência) is the time during which a plan member, although already paying monthly premiums, is not yet entitled to certain procedures. The law sets maximum limits for these periods, and exceeding them is an irregular practice.

The maximum limits are up to 180 days for most procedures, 300 days for full-term childbirth, and only 24 hours for urgent and emergency cases. That last point tends to be the one most often ignored in practice.

When there is an immediate risk to life or of irreparable injury, coverage must be immediate, even if the contract is recent. Denying emergency care on the basis of a waiting period in these situations directly violates the rule and has repeatedly been rejected by the courts.

Another relevant scenario involves the portability of waiting periods. A plan member who switches plans within the regulatory agency’s rules can carry over the periods already completed, avoiding a restart of the count from zero. The new provider cannot simply ignore this right.

Preexisting Conditions: Limits on the Provider’s Argument

A preexisting condition is one that the plan member knew about at the time of signing up. In these cases, the provider may impose what is known as temporary partial coverage (cobertura parcial temporária), which suspends, for a fixed period, high-complexity procedures and surgeries directly related to the declared condition.

That period, however, has a ceiling: no more than 24 months from the date the contract was signed. After that, coverage must be full, and the former condition cannot serve as a pretext for new denials.

An administrative denial is not the final word: most refusals based on the agency’s list or on a preexisting condition give way under judicial review.

There is also a sensitive point that is often overlooked. If the provider suspects the plan member of concealing information, it cannot simply cancel the contract or deny treatment on its own. The rule requires it to open a proceeding before the regulatory agency to prove bad faith, with the consumer given the right to a defense.

Without that proceeding, a denial based on a supposed preexisting condition loses its footing. The burden of proving fraud falls on the provider, not the other way around.

Treatment Outside the Agency’s List: The 2022 Legislative Shift

The regulatory agency’s list of procedures sets out the coverage that plans are required to provide. For years, there was debate over whether this list was exhaustive, meaning an absolute limit, or merely illustrative, serving as a minimum baseline.

In 2022, after a restrictive decision by the Superior Tribunal de Justiça (Brazil’s Superior Court of Justice), Congress passed Law 14.454/2022, which changed the landscape. The law established that the list works as a basic reference, but coverage of an unlisted treatment can be demanded when there is proof of effectiveness, a recommendation from a competent technical body, or support from scientific evidence.

In practice, this means that the mere absence of a procedure from the official list is not enough to justify a refusal. If there is a well-founded medical prescription and scientific support, the plan member has a solid argument for demanding coverage.

Treatment for autism spectrum disorders, multidisciplinary therapies, oral cancer medications, and newer surgical techniques are among the cases that generate the most litigation in this area. The trend in the decisions is to protect the medical prescription against a purely administrative denial.

How to Overturn a Denial, Step by Step

The first step is to demand the denial in writing, with an express statement of the reason and of the contract clause or rule being invoked. The provider is required to supply this formal justification, and the document becomes the centerpiece of any later challenge.

Next, it is advisable to gather a detailed medical report explaining the diagnosis, the urgency, and the reason the denied treatment was prescribed. The more technical and specific the report, the stronger the request.

With the formal denial and the medical documentation in hand, the plan member can file a complaint with the regulatory agency and with consumer protection bodies. These administrative channels resolve a significant share of cases without the need for a lawsuit.

When the administrative route does not solve the problem, or when the wait puts health at risk, the path to court opens. In these situations, it is possible to request an urgent ruling ordering the provider to pay for the treatment immediately, even before the final judgment.

When a Denial Gives Rise to a Right to Compensation

Not every wrongful refusal is limited to an obligation to pay for the procedure. In certain contexts, the denial also gives rise to compensation for pain and suffering (dano moral, or non-pecuniary damages), especially when it worsens the distress of someone already facing a serious illness.

The courts tend to recognize this harm when the refusal comes at a critical moment, such as an emergency hospitalization, a surgery already scheduled, or the interruption of ongoing treatment. The anguish caused by that uncertainty, in these cases, goes beyond a simple breach of contract.

The amount of compensation varies with the seriousness of the situation, the provider’s conduct, and the consequences for the plan member. Repeated similar denials by the same company also tend to weigh on the amount awarded.

Frequently Asked Questions

Can the provider deny emergency care by claiming a waiting period?

Not in situations involving an immediate risk to life or of irreparable injury. The law sets a maximum waiting period of 24 hours for urgent and emergency care, so denying this type of care on the grounds that the contract is recent violates the rule and is usually reversed in court.

Can a treatment that is not on the regulatory agency’s list be demanded?

Yes, under certain conditions. Since Law 14.454/2022, the list is a basic reference, not an absolute limit. With a well-founded medical prescription, proof of effectiveness, and scientific support, the plan member can demand coverage even for an unlisted procedure, and a purely administrative refusal tends to be set aside.

How long can the provider suspend coverage for a preexisting condition?

The maximum period is 24 months from the date the contract was signed, under temporary partial coverage. After that, coverage must be full. To allege that the plan member concealed information, the provider must open its own proceeding before the regulatory agency, guaranteeing the right to a defense, and it cannot deny treatment on its own.
