Waiting period portability: what changes for the hospital
Waiting period portability lets plan members switch plans without restarting waiting periods, but the hospital cannot assume the payer has accepted the request. See the requirements of ANS Normative Resolution 438/2018 and how to confirm the patient’s portability

Waiting period portability allows plan members to switch health plans without having to serve again the waiting periods they already completed under the previous plan. For the patient, this means immediate access to coverage that would normally require a waiting period. For the hospital, it means that admitting a patient who claims portability calls for verification, not assumption.
Authorizing a procedure based on portability the hospital has not confirmed is a direct denial risk: if the receiving payer does not recognize the request, the waiting period may be enforced as usual, and the hospital runs the risk of not being paid for care already provided.
What waiting period portability is
Waiting period portability is the plan member’s right to switch health plans, with the same payer or another, without serving again the waiting periods already completed under the original plan. The rule is set out in Normative Resolution 438/2018 of the ANS (Brazil’s National Supplementary Health Agency) and replaces the standard waiting periods of a new contract, which impose waiting times from the start of the contract.
Portability does not eliminate waiting periods for coverage that the new plan offers and the original plan did not. In these cases, the payer may require a waiting period only for the new part of the coverage, not for what was already covered.
Requirements for plan members to exercise portability
Minimum time in the plan
The plan member must have stayed in the current plan for at least two years. The minimum rises to three years when the member served Temporary Partial Coverage (CPT) for a pre-existing disease or condition.
Request window
In standard portability, the request must be made within the period of 120 days before or after the contract anniversary. Outside that window, the receiving payer may require the waiting periods to be served as usual.
Compatibility between plans
The new plan must have coverage compatible with the original plan, as verified through the ANS Health Plan Guide. The plan member must also be current on payments and have an active contract at the time of the request.
Special portability: when the rules change
In specific situations, portability happens under more flexible rules, with no requirement for price compatibility between the plans: dismissal or retirement with loss of the employment relationship, death of the primary holder, bankruptcy of the payer, or removal of the plan member due to the termination of a self-managed plan agreement. This last scenario is regulated together with Normative Resolution 649/2025, which deals with the exit of sponsors from self-managed health plans.
In special portability, the plan member can choose any plan on the market, and the deadline for the request tends to be shorter, which calls for extra attention from the hospital to quickly confirm which payer is actually responsible for the care.
What changes for the hospital when admitting the patient
When a patient says they are in the process of portability and asks to be treated without serving a waiting period, the hospital should not accept that information on the patient’s word alone. It must confirm with the receiving payer whether the portability request has in fact been accepted and is active before waiving any waiting period.
Treating portability as confirmed without this verification exposes the hospital to the same kind of risk found in other situations involving a change of plan: the payer may refuse coverage, citing a waiting period that was not transferred, generating an administrative denial for care that has already been provided and cannot be undone.
How to reduce the risk of denials due to poorly verified waiting periods
Including a check of the portability request in the patient admission routine, together with standard eligibility verification, keeps the team from taking portability for granted before formal confirmation from the payer.
This means integrating this verification into the same process that already covers other plan and coverage validations, rather than treating it as a separate manual exception. Looking at how a hospital audit works helps clarify where this kind of check fits within the admission and billing routine.
Waiting period portability requires verification
Waiting period portability is an established right of plan members, but a hospital that treats the request as automatic takes on unnecessary financial risk. Confirming the request before waiving the waiting period is what separates safe care from an avoidable denial.
Rivio is an artificial intelligence platform that helps hospitals verify eligibility and portability status in real time during patient admission, reducing the risk of denials due to unconfirmed waiting periods.
Frequently asked questions about waiting period portability
What is waiting period portability?
It is the plan member’s right to switch health plans without serving again the waiting periods already completed under the previous plan, regulated by ANS Normative Resolution 438/2018.
What are the requirements for standard portability?
A minimum of two years in the current plan (or three with CPT served), a request within 120 days of the contract anniversary, being current on payments and compatibility between the original and new plans.
What is special waiting period portability?
It is portability applied in situations such as dismissal, death of the primary holder or bankruptcy of the payer, with no requirement for price compatibility between the plans and with shorter deadlines for the request.
Can the hospital waive the waiting period just because the patient claims portability?
It should not. Ideally, the hospital should confirm with the receiving payer whether the portability request was accepted before waiving any waiting period, to avoid a denial for a waiting period that was not transferred.
Does portability eliminate all waiting periods in the new plan?
Not necessarily. It transfers waiting periods already served to equivalent coverage, but the payer may require a waiting period for new coverage that did not exist in the original plan.
