Health plan reimbursement: know the rules

Health plan reimbursement happens when the patient pays for care directly and then asks the payer to reimburse that amount. For the hospital, this changes the billing routine: instead of billing the health plan, the bill is issued directly to the patient, who then depends on the documentation received to get reimbursed.

Understanding when reimbursement is due, which documents the hospital needs to issue and what deadline ANS (Brazil’s National Supplementary Health Agency) sets helps reduce complaints and rework, since many reimbursement denials are linked to documentation failures, not to coverage itself.

What health plan reimbursement is

Reimbursement is the repayment the health plan makes to a plan member who paid out of pocket for care covered by the plan. Unlike direct billing to the health plan, in which the hospital sends the claim through the TISS system, with reimbursement the hospital bills the patient as a self-pay patient, and it is the patient who requests repayment from the payer.

This arrangement is common in plans with a free choice of provider option, but it can also occur when the payer fails to guarantee care within its own accredited network.

When the plan member is entitled to reimbursement

Free choice of provider

Plans that offer a free choice option allow the plan member to use any professional or hospital, even outside the accredited network, and then request reimbursement. In this case, the amount repaid follows the limits set in the contract, which are usually lower than the amount actually charged by the hospital.

Payer failure to guarantee a network

When the payer does not provide an in-network provider for the service required within the established deadlines, the plan member can seek care outside the network and is entitled to full reimbursement of the amount paid, including transportation expenses when applicable.

Which documents the hospital needs to issue for the patient to get reimbursed

The payer only accepts a reimbursement request with a tax document or equivalent that proves the care and the payment. This means the hospital needs to issue an invoice or detailed receipt, clearly itemizing the procedure performed, the amount charged, the date of care and the identification of the professional responsible, including their professional council registration number.

Incomplete documentation is one of the most common causes of reimbursement being denied to the patient, even when the care itself is covered by the plan. Generic receipts, without itemization of the procedure or without the professional’s details, are often rejected by the payer.

Reimbursement deadline and what changes if the documentation is incomplete

The payer has up to 30 days from the date of the request to complete its review and pay the reimbursement. This period only starts once the documentation is complete: requests with missing information are usually returned to the patient for correction, which restarts the count and delays payment.

Checking how hospital billing by type of care works helps explain why reimbursement, direct health plan billing and self-pay care require different document issuing routines within the same hospital.

Reimbursement or direct billing to the payer: what changes for the hospital

In direct billing, the hospital sends the claim to the payer through the TISS system, subject to the payer’s own technical and administrative audit, with the risk of denial. With reimbursement, the hospital bills the patient directly, without going through the denial process, but the quality of the documentation issued directly affects the patient’s chance of getting the money back.

When the plan includes copayment, the payer may deduct that amount from the reimbursement before paying the plan member. Understanding how copayment in health plans works helps the hospital better advise the patient on the amount that will actually be repaid.

Hospitals that serve a significant volume of reimbursement patients benefit from having a dedicated document issuing routine for this arrangement, separate from the health plan hospital billing flow, to reduce errors and complaints.

Reimbursement depends on documentation, not just coverage

Most reimbursement problems are not related to plan coverage, but to failures in how the hospital issues documents. Standardizing the issuing of invoices and receipts for reimbursement patients reduces complaints and keeps the hospital from being called on to correct documentation already sent to the patient.

Rivio is an artificial intelligence platform that helps hospitals standardize the issuing of tax documents and automatically check that the information the payer requires is complete before it is handed to the patient, reducing rework in reimbursement cases.

Frequently asked questions about health plan reimbursement

What is health plan reimbursement?

It is the repayment the payer makes to a plan member who paid directly for care covered by the plan, usually in cases of free choice of provider or the payer’s failure to guarantee a network.

Which documents should the hospital provide for the patient to request reimbursement?

An invoice or receipt itemizing the procedure, the amount charged, the date of care and the details of the professional responsible, including their professional council registration number.

How long does the payer have to pay the reimbursement?

The payer has up to 30 days to complete its review and make the payment, counted from the date of a request with complete documentation.

Why can a reimbursement request be denied?

The most common causes are incomplete or incorrect documentation, a procedure outside contract coverage, care without a formal medical indication or a request made after the deadline set by the payer.

Is reimbursement the same as billing the payer?

No. With reimbursement, the hospital bills the patient directly and does not go through the health plan’s audit and denial process. The quality of the documentation issued to the patient is what determines whether the reimbursement will be approved.
