Medicare is making significant changes in how it handles certain medical services through the new Wasteful and Inappropriate Service Reduction (WISeR) Model. This innovative approach uses artificial intelligence and machine learning to streamline prior authorization processes while protecting you from unnecessary procedures. The WISeR Model aims to reduce the billions Medicare spends on healthcare waste and will run from January 1, 2026, through December 31, 2031.
What is WISeR?
The WISeR Model represents CMS’s commitment to protecting both federal taxpayers and Medicare beneficiaries from fraud, waste, and abuse. According to the Medicare Payment Advisory Commission, Medicare spent up to $5.8 billion in 2022 on unnecessary or inappropriate services with little to no clinical benefit. This waste doesn’t just drain resources, but it can actually harm patients by subjecting them to invasive procedures they don’t need.
Healthcare waste represents up to 25% of all health care spending in the United States, making this a critical issue that affects millions of Americans. When you receive unnecessary medical procedures, you face potential complications, recovery time, and stress that could have been avoided entirely. The WISeR Model specifically targets services that have been identified as particularly problematic in terms of overuse and inappropriate application.
You’ll find that WISeR aligns with three key strategic directions from the CMS Innovation Center. First, it promotes evidence-based prevention by ensuring you receive the most appropriate and effective care, potentially reducing your need for costly and invasive treatments. This approach means you’re more likely to receive preventive care that keeps you healthier rather than expensive procedures that may not benefit your condition.
Second, the model empowers you to work with your healthcare providers on the most effective care plans while providing more information about your treatment options. You’ll have access to clearer explanations about why certain treatments are or aren’t recommended for your specific situation. Third, it creates competition among companies to provide better service by using new technologies in Original Medicare and rewarding companies that make fast, accurate, and clear authorization decisions.
Does WISeR Affect Your Coverage?
Your Medicare coverage and payment policies won’t change under the WISeR Model. You’ll still have the freedom to seek care from any Original Medicare provider or supplier you choose, and providers will receive the same payments for covered services. This means you won’t see any changes in your Medicare card, your benefits, or the amount you pay for covered services.
The model doesn’t apply to Medicare Advantage plans, so if you have Medicare Advantage, WISeR won’t impact you at all. Your Medicare Advantage plan will continue to operate under its existing rules and procedures. Only people with Original Medicare in selected regions will experience the changes that come with WISeR implementation.
What changes is the process for reviewing certain services before they’re provided. The model targets specific items and services that are vulnerable to fraud, waste, and abuse. These include things like skin and tissue substitutes, electrical nerve stimulators, and knee arthroscopy for knee osteoarthritis. These services were chosen because they may pose patient safety concerns if delivered inappropriately, have existing publicly available coverage criteria, and have been associated with previous reports of fraud, waste, and abuse.
The model deliberately excludes inpatient-only services, emergency services, and services that would pose a substantial risk to patients if substantially delayed. This means if you need emergency care or are admitted to the hospital, you won’t face any delays due to WISeR requirements. Your urgent medical needs will always take priority over administrative processes.
The Prior Authorization Process
When you need one of the selected services, your provider will have two options. They can submit a prior authorization request before providing the service, or they can provide the service and submit it for post-service medical review. This flexibility ensures that you won’t be denied necessary care, but it also creates accountability for providers who choose to proceed without prior authorization.
If your provider chooses the prior authorization route, they’ll send all relevant information either directly to the participating company in your region or to your Medicare Administrative Contractor, which will then route it to the model participant. This streamlined process is designed to be more efficient than current systems while maintaining thorough review standards.
The participating companies will use enhanced technology, including AI and machine learning, to support coverage determinations. However, any recommendations that coverage shouldn’t be approved will always be made by an appropriately licensed human clinician, not a machine. This human oversight ensures that your individual circumstances and medical complexity are properly considered in every decision.
These clinicians will apply standardized, transparent, and evidence-based procedures to their reviews, ensuring that medical expertise remains central to the decision-making process. You can expect consistency in how decisions are made, regardless of which participating company handles your case. The standardized approach means similar cases should receive similar outcomes, reducing arbitrary variations in coverage decisions.
Company Accountability and Requirements
The companies participating in WISeR must meet strict requirements to ensure they’re qualified to handle your healthcare decisions. They need proven expertise in understanding and implementing clinical coverage standards that come from Medicare’s national and local coverage policies. This expertise ensures they understand Medicare’s existing coverage policies and can apply them correctly to your specific situation.
They must also have a track record of successfully using advanced technology with various healthcare payers and insurance plans to make approval processes more efficient. This requirement means the companies aren’t experimenting with new systems on Medicare beneficiaries but are bringing proven technologies and processes to the Medicare system.
You can expect prompt responses to authorization requests and any follow-up submissions from these companies. They’re required to incorporate appropriate clinical expertise into the pre-approval process and conduct thorough medical reviews. Companies must demonstrate their ability to handle the volume of requests they’ll receive while maintaining quality and accuracy in their decisions.
Additionally, they must comply with all federal and CMS data protection and security requirements, including HIPAA regulations and other privacy and security laws. Your personal health information will be protected with the same stringent standards that apply to all Medicare operations. If advanced technologies fail, they must offer backup options like phone, fax, electronic portals, and regular mail, ensuring you’re never left without options for communication.
Your Rights and Appeal Options
You maintain all your existing rights under the WISeR Model, including the ability to appeal decisions. If your provider receives a “non-affirmed” prior authorization request, meaning the future service was found not to meet Medicare coverage, coding, or payment requirements, your provider has unlimited opportunities to resubmit the request with additional information.
This unlimited resubmission opportunity is particularly important because it allows your provider to gather additional documentation or clarify aspects of your case that may not have been clear in the initial request. You won’t be penalized if the first submission doesn’t include all necessary information.
A non-affirmed decision doesn’t prevent your provider from delivering the service and submitting a claim. If your provider chooses to proceed and the claim is denied by the Medicare Administrative Contractor, this creates an initial payment determination that you can appeal through existing administrative processes. You’ll have the same appeal rights you’ve always had under Original Medicare, ensuring your access to appropriate care remains protected.
The appeal process remains the same multi-level system you’re familiar with, starting with redetermination by the Medicare Administrative Contractor and potentially progressing through multiple levels of review. At each level, you’ll have the opportunity to present additional evidence and arguments supporting your case.
Conclusion
The WISeR Model represents a significant step forward in Medicare’s efforts to eliminate wasteful spending. By leveraging advanced technology and maintaining human oversight, the model makes prior authorization faster and more accurate while reducing inappropriate procedures that can harm patients. You’ll continue to receive the same Medicare benefits you’ve always had, with the added protection of enhanced review processes for services prone to abuse.
The model’s success will depend on participating companies meeting strict performance standards and maintaining transparency in their decision-making processes. When WISeR launches in 2026, you can expect improved efficiency in healthcare delivery while maintaining the quality and accessibility of your Medicare benefits.
