RN 649/2025: what changes in billing for self‑managed plans

ANS Normative Resolution (RN) 649/2025 took effect on July 1, 2026, and updates the rules for self-managed health plan operators. Although the regulation directly governs self-managed plans, it also affects hospitals that serve this type of payer, especially in the provisions on network sharing and the exit of sponsors.

Understanding what changes with RN 649/2025 helps the billing team anticipate denial risks and review eligibility verification routines before problems show up in billing.

What RN 649/2025 is

RN 649/2025 is the ANS (Brazil’s National Supplementary Health Agency) normative resolution that updates RN 137/2006, the regulation that has governed self-managed health entities since 2006. The new resolution also fully revokes Normative Instruction 20/2022, consolidating the rules on the subject into a single text.

Published on October 31, 2025, RN 649/2025 took effect on July 1, 2026, after a transition period that allowed self-managed plans to adjust their bylaws, contracts and internal processes to the new regulation.

Self-managed plans are nonprofit payers that administer health plans for a closed group of members, usually employees, retirees and dependents of a company, government body or association. Unlike commercial payers, they do not sell plans on the open market.

Main changes introduced by the regulation

Expanded member eligibility

RN 649/2025 expands the groups allowed to join self-managed plans, including relatives of the policyholder up to the fourth degree, persons under guardianship and formally recognized dependents. The change increases the potential member base, but it also requires hospitals to update their criteria for verifying membership at the point of care.

Mandatory minimum governance

The regulation requires self-managed plans to have a minimum governance structure, with a board of directors or equivalent body, an executive board and a fiscal council, ensuring that policyholders and sponsor representatives take part in decision-making bodies. This point has an indirect impact on billing, since it reinforces the institutional stability of the contracting payer.

Network sharing and waiting period portability

RN 649/2025 now allows self-managed plans to share their care network with other payers of any type, including for coverage in a location outside their area of operation, limited to 10% of the total members in the portfolio. The regulation also guarantees waiting period portability for members who lose their coverage when a sponsor withdraws from the self‑managed plan.

How RN 649/2025 affects hospital billing

Network sharing between self-managed plans and other payers creates a direct risk for billing: each payer may apply a different reference table and different technical audit rules to the same procedure. A hospital that treats a member through a shared network needs to know exactly which payer is paying the claim and which table applies to that specific contract, or it risks an administrative denial due to a discrepancy.

The exit of a sponsor also requires attention. Under the regulation, a sponsor that decides to stop funding the self-managed plan must give 90 days’ notice, and the self-managed plan has 60 days to notify members that the agreement is ending. In that interval, hospitals without real-time communication with the payer run the risk of treating and billing for members who have already lost their coverage, generating denials that may not be eligible for appeal.

Keeping contracts up to date and eligibility verification processes agile reduces exposure to this type of denial. Checking what characterizes an administrative denial and how to avoid it helps the billing team identify these cases before they become recurring.

What the hospital should review to comply

Compliance with RN 649/2025 does not depend only on the self-managed plan. Hospitals that serve this type of payer also need to adjust internal routines.

Map which contracts involve self‑managed plans

Identifying which of the hospital’s health plans are self-managed payers, and which of them take part in network-sharing agreements, is the first step to knowing where the risk of table discrepancies is greatest. Checking which CBHPM or AMB table is in force in each contract helps avoid this type of error.

Update eligibility verification in real time

Hospitals that rely on manual membership checks are at greater risk under the new sponsor exit rule. Automating this check at the point of care reduces the chance of billing for a member who has already been removed.

Review shared network contract clauses

Contracts that provide for care through a shared network should clearly specify which table and which audit rules apply to each payer involved. This avoids ambiguity at billing time and makes it easier to dispute an improper denial, protecting the hospital’s revenue cycle as a whole.

RN 649/2025 requires routine, not just legal compliance

Complying with RN 649/2025 is the self-managed plan’s responsibility, but a hospital that serves this type of payer also needs to adjust its processes so it is not caught off guard by denials related to network sharing or a change of sponsor. Treating the regulation as a trigger to review billing routines, not just as a distant regulatory requirement, reduces this risk.

Checking how to review a contract with a health plan helps identify clauses that need updating in light of the changes the regulation brings.

Artificial intelligence tools already help hospitals automate eligibility verification and identify table discrepancies in real time, reducing exposure to denials caused by regulatory changes like this one.
