Health Law: health plans, treatments and patients' rights in Brazil
Did your health plan deny a procedure, medication or treatment? Do you have questions about coverage for ABA therapy, home care or other health services?
The relationships between patients, health plan operators and service providers are subject to contracts, specific legislation and regulatory rules.
Depending on the circumstances, there may be possibilities for administrative review of the denial, complaints before the competent bodies and analysis of the appropriate court measures.
The assessment depends on the contract terms, the medical indication, the applicable regulation and the documents of each situation.
Common situations
On this page
Coverage denials, medication, ABA therapy and home care: understand the applicable legal criteria and the alternatives that may exist in each case in Brazil.
Coverage denials
Contractual criteria, ANS regulation, reasons for denial and possibilities of challenge.
Relationships with health plans in Brazil are regulated by Law No. 9,656/1998 (in Portuguese), by the rules of the National Supplementary Health Agency (ANS) and, as a rule, by the Consumer Protection Code. A coverage denial usually has reasons such as:
- a procedure considered outside the contracted coverage;
- a waiting period;
- lack of prior authorization or of an indication considered sufficient;
- a gap between what the doctor prescribed and what the operator authorizes.
Not every denial is improper, and not every denial is legitimate. The analysis checks the type and date of the contract, the coverage, what the law and ANS rules establish for that procedure, the justification given in writing, the attending physician's indication and the urgency of the case. Depending on the situation, it is possible to challenge the denial with the operator itself, file a complaint with the ANS or assess a court measure.
Therapies and ongoing treatments
Legal criteria on specialized therapies, including ABA, without presuming automatic coverage.
Ongoing therapies, such as those prescribed to people with autism spectrum disorder (for example, ABA therapy), raise frequent questions. The ANS has rules on coverage of therapies for pervasive developmental disorders, and the attending physician's indication weighs in the analysis, but coverage is not automatic in every case.
The following are usually relevant:
- the report of the professional who prescribed the therapy, with frequency and duration;
- what the contract and the regulation provide for that type of care;
- the accredited network and the possibility of adequate care;
- the denial or limitation issued by the operator, in writing.
Home care
Contractual and regulatory issues applicable to home care.
Home care is health care provided at home. Whether a health plan covers it depends on the contract, ANS rules and the patient's condition. The analysis usually considers:
- the medical indication for home care and the need for continuous care;
- the contract clauses on hospitalization and care at home;
- the comparison with hospital admission and the alternatives offered;
- the documents that prove the clinical situation.
Each case is assessed with its own documents, and no result is guaranteed.
High-cost medication
The difference between issues involving health plans and the public health system (SUS), according to legislation and case law.
The supply of high-cost medication may involve the health plan or the public authorities (the public health system, SUS), depending on the case. Courts usually examine the proven need for the medication, the existence of alternatives and registration with the National Health Surveillance Agency (Anvisa).
- Health plan: contract, coverage and ANS rules;
- SUS: official lists, protocols and criteria set by case law for medication outside them;
- the medical report and tests that support the request;
- urgency and deadlines.
We do not claim that every denial is unlawful: the conclusion depends on each situation.
Patients' rights
Rights, duties, medical information, consent and privacy.
Patients have the right to information about the diagnosis, the risks and the treatment alternatives, and may accept or refuse interventions, as a rule, after free and informed consent. They also have the right to privacy: under Brazil's General Data Protection Law (LGPD), health data is treated as sensitive data.
- access to the medical record and to information about the care received;
- consent to treatments and research;
- decisions about one's own treatment, including advance directives;
- confidentiality and proper use of health data.
Advice for clinics and professionals
Professional liability, contracts and data protection.
Health professionals, clinics and institutions have their own legal needs:
- service agreements and contracts with health plan operators;
- professional liability and the duty to inform the patient;
- confidentiality and protection of health data;
- partnerships between professionals and organization of the practice;
- defense in complaints and lawsuits.
Bioethics and Biolaw
Autonomy, consent and human dignity in health decisions.
Bioethics and Biolaw deal with the ethical and legal limits of health decisions: patient autonomy, informed consent, end-of-life decisions, research with human beings and the use of new technologies. The education in Law, Biology and Bioethics of part of the team allows the legal aspect to be examined in dialogue with the clinical and ethical ones.

Frequently asked questions
Can a health plan deny a treatment prescribed by the doctor?
There may be a denial for contractual or regulatory reasons, but that does not mean it is correct. The analysis checks the contract, Law No. 9,656/1998, ANS rules, the operator's justification and the attending physician's indication. Only with this analysis is it possible to say whether the denial has grounds.
Which documents are usually relevant in health claims?
The plan contract, the member card, the written denial, the attending physician's report and prescription, tests, reports and records of contacts with the operator. Gathering these documents early helps the analysis and the deadlines.
Does the health plan have to cover ABA therapy?
It depends on the contract, ANS rules and the professional's indication, and coverage is not automatic in every case. The report that prescribed the therapy, the coverage provided, the available network and what was denied are examined. The analysis is individual.
What can be considered in situations involving home care?
The medical indication for home care, the contract clauses on hospitalization and care at home, the comparison with hospital admission and the report on the need for continuous care. Each situation is assessed with the documents of the case.
Who provides a high-cost medication, the plan or the SUS?
It depends on the case. If the medication is covered by the contract and ANS rules, the obligation may fall on the plan. If not, the SUS route may be assessed, using the criteria set by case law for medication outside the official lists. In both cases, the medical report and Anvisa registration carry weight.
How do Bioethics and Biolaw relate to conflicts in the health field?
They provide the principles, such as autonomy, informed consent and human dignity, that guide the legal reading of conflicts. They help analyze decisions about treatments, use of data and the limits of medical intervention, always in dialogue with the applicable law.
