WISeR rules: decision times, UTN, resubmission and exemption

What CMS’s WISeR Model Provider and Supplier Operational Guide says about how a WISeR request is decided, tracked, resubmitted and exempted — each rule quoted with its section. Version 7.0, last updated July 24, 2026. The hospital outpatient program and the ASC demonstration run on different clocks (7 calendar days); see their pages.

Decision time frames

How long does a WISeR prior authorization decision take?

WISeR Participants will typically issue a determination to the requester within 3 calendar days of receiving the initial or resubmitted request.

WISeR Operational Guide v7.0, §4.2.1 · CMS document

How fast is an expedited WISeR request?

If the WISeR Participant confirms this risk, the WISeR Participant will process the prior authorization request and communicate a decision to the requester within 2 days of receipt of the expedited request.

WISeR Operational Guide v7.0, §4.2.2 · CMS document

How long is there to send records under pre-payment review?

For pre-payment medical review, WISeR Providers and WISeR Suppliers will have 45 calendar days from the date of the request for documentation from the WISeR Participant to submit their clinical documentation.

The UTN (unique tracking number)

Who assigns the WISeR UTN (unique tracking number)?

Each prior authorization request will be assigned a UTN generated by the MAC.

WISeR Operational Guide v7.0, Section 4 · CMS document

Does the UTN go on the claim?

WISeR Providers and WISeR Suppliers will need to ensure the UTN is included on each submitted claim if the service is rendered, regardless of whether the prior authorization request determination is an affirmation or non-affirmation

WISeR Operational Guide v7.0, Section 4 · CMS document

How long is an affirmed WISeR decision valid?

Once a prior authorization request is approved, the UTN associated with it is valid for 120 calendar days starting from the decision date (the date it was approved).

WISeR Operational Guide v7.0, §4.3 · CMS document

Non-affirmation, resubmission and appeal

Is WISeR prior authorization mandatory?

Submitting prior authorization requests for WISeR Select Items and Services is voluntary; however, if a claim for a WISeR Select Item or Service is submitted without a prior authorization request decision on file, the MAC will suspend the related claim and re-route it to the WISeR Participant to conduct pre-payment medical review.

WISeR Operational Guide v7.0, §7.2 · CMS document

How many times can a non-affirmed WISeR request be resubmitted?

Unlimited resubmissions are permitted.

WISeR Operational Guide v7.0, §4.4 · CMS document

What must a resubmission include?

The requester must include the original non-affirmed UTN on the resubmitted prior authorization request.

WISeR Operational Guide v7.0, §4.4 · CMS document

Is peer-to-peer review available?

When resubmitting a request, the requester may request peer-to-peer clinical review to inform the new determination.

WISeR Operational Guide v7.0, §4.4 · CMS document

Can a non-affirmed WISeR request be appealed?

A prior authorization request that is non-affirmed is not an initial determination on a claim for payment for services provided and, therefore, would not be appealable; however, the requester has an unlimited number of opportunities to resubmit a prior authorization request, provided the claim has not yet been submitted and denied.

WISeR Operational Guide v7.0, Section 10 · CMS document

Exemption (“gold card”) — Section 5, verbatim

Beginning in July 2026, CMS and WISeR Participants have implemented a process to automatically exempt individuals who are WISeR Providers or WISeR Suppliers from the prior authorization process and pre-payment medical review upon demonstration of compliance with Medicare coverage, coding, and payment rules. Participants grant exemption status at the individual provider National Provider Identifier (NPI) level, not the facility or organizational level. Providers and Suppliers who achieve exemption status are exempt for all lines of business (that is, Medicare Part A and Part B) for all WISeR Select Items and Services, across all sites of care. To achieve Exemption Status, a provider must do the following:

1. Submit at least 10 prior authorization requests across WISeR Select Items and Services during an exemption assessment period

2. Achieve a minimum prior authorization request affirmation rate threshold during an exemption assessment period. WISeR Participants have flexibility with designing their exemption programs, but all must apply the above minimal baseline parameters when determining exemption status. Additional Participant- specific criteria are publicly posted by the WISeR Participants. WISeR Participants also deliver provider education related to the Exemption Program. WISeR Providers and Suppliers will be added to the Exemption Status list on a quarterly basis. WISeR Participants will inform exempted providers and suppliers prior to the start of each quarter when they have been added to the exemption status list. The notification will specify the effective date of Exemption Status, the Exemption Status duration, and the process for reevaluating Exemption Status.

5.1 Claims Submissions for Exempted Providers When submitting claims for services furnished by exempted providers, the field in which the exempted provider's NPI must be submitted differs depending on the site of service. In the office and home settings, the exempted NPI should be included in the rendering provider field. In the ambulatory surgery center setting, the exempted NPI should be in the referring/ordering provider field. In the outpatient department setting, the exempted NPI should be in the operating provider field.

5.2 Reevaluation of Exemption Status Exempted WISeR Providers and Suppliers will maintain their status for at least a year (or longer per WISeR Participant discretion). WISeR Participants will reevaluate Exemption Status by issuing no more than 10 additional documentation requests (ADRs) per year, examining continued compliance with Medicare coverage criteria. After reevaluation is completed, WISeR Participants will notify any providers who lose Exemption Status at least 60 days before the start of the next quarter. The notification will include the effective date of removal and the process for re-earning Exemption Status.

Each participant’s affirmation-rate threshold

CMS sets the baseline (at least 10 requests and a minimum affirmation rate); each participant sets its own threshold. We show a number only where the participant or a source it cites has published one.
