Prior authorization means doctors must get approval from the insurer before giving some services, tests, or medicines to patients. Usually, prior authorization is common in Medicare Advantage plans, private managed care, Medicaid, and commercial insurance. Original Medicare, also called Traditional Medicare, had fewer prior authorization rules. These mostly applied to some equipment and outpatient services.<\/p>\n
Data from the Centers for Medicare and Medicaid Services (CMS) shows that almost all people in Medicare Advantage\u2014about 99%\u2014need prior authorization for some services. But Traditional Medicare had fewer than 400,000 prior authorization requests in 2023. This shows Traditional Medicare had fewer such rules but also a bigger risk of waste and fraud.<\/p>\n
The WISeR Model pilot will be the first time Original Medicare requires prior authorization for 17 services seen as \u201chigh risk\u201d for wrong use or fraud. These include things like electrical nerve stimulators, special skin substitutes, epidural steroid shots, and some spine surgeries. The pilot started in six states. CMS might expand it nationwide depending on how it goes.<\/p>\n
The main goal of the WISeR Model is to cut down on unnecessary spending in Medicare Part B by checking claims more carefully before paying. Waste, fraud, and abuse have long been problems for Medicare\u2019s budget. For example, in 2025, the Justice Department charged over 300 people for Medicare fraud, including a skin graft fraud case with losses over $1 billion.<\/p>\n
WISeR often focuses on services with doubtful medical need or too much use, like chronic wound care products and some pain treatments.<\/p>\n
The model uses new technology such as artificial intelligence (AI) and machine learning to help review prior authorization requests. AI helps check claims in advance by pointing out suspicious or risky patterns. But CMS says AI will not decide final approvals. Licensed clinicians will make the final decisions. This keeps human judgment in medical choices.<\/p>\n
Doctors and their teams already spend a lot of time handling prior authorizations. A 2022 American Medical Association (AMA) survey found that doctors do about 45 prior authorizations each week and spend around 14 hours on related tasks. This costs thousands of dollars a year in staff time and resources for many primary care doctors.<\/p>\n
With the WISeR Model, providers in the six states will need prior authorization for 17 new Medicare Part B services that did not need it before. This means more paperwork, phone calls, and online forms. Practice managers will have to train billing and clinical staff on new rules and processes.<\/p>\n
Some experts worry that adding a third-party review group paid to save money might cause more claim denials or delays. Michael Baker from the American Action Forum says this extra step could make paperwork harder, not easier.<\/p>\n
One big concern with prior authorization is that it can delay patient care. Most doctors (94% in the AMA survey) said patient care got delayed because of prior authorizations. Also, 80% saw patients stop recommended treatments because of these delays.<\/p>\n
The WISeR Model does not require prior authorization for emergency services and inpatient-only procedures. This is to protect patients who need quick care. But outpatient and ambulatory services like wound care and some procedures will have longer approval times. This might cause delays, especially in busy or short-staffed clinics.<\/p>\n
CMS rules say expedited prior authorizations must be answered within 72 hours and regular ones within seven calendar days starting in 2026. Still, there is worry about whether these reviews will be fast enough given the extra work.<\/p>\n
To get prior authorization approved, providers must show clear medical need according to Medicare rules. This means medical records, billing, and coding must be very complete and accurate.<\/p>\n
CMS tells providers to prepare by training staff, checking clinical records, and setting up ways to track denials or delays and appeal them. If documentation is weak, services might be denied or require payment back, which means financial risk.<\/p>\n
The WISeR Model is part of a bigger effort by CMS and the Department of Health and Human Services (HHS) to change prior authorization rules for public and private insurers. Starting January 1, 2027, CMS requires an electronic prior authorization system for Medicare Advantage, Medicaid, CHIP, and qualified health plans.<\/p>\n
This rule expects insurers to give faster prior authorization responses, use standard denial reasons, and report data publicly. The goal is to make the process clearer and reduce delays.<\/p>\n
Some early users of prior authorization automation had good results. One health plan using an electronic system based on HL7 Da Vinci FHIR standards auto-approved 60% of requests. This cut down the work for staff. Providers also increased their processing speed from 3-5 requests per hour to 12-15 with real-time submissions and reviews. This shows technology can help make things faster and easier if done right.<\/p>\n
The WISeR Model uses AI to check for waste and fraud risks in claims. AI finds patterns or strange cases that humans might miss. It helps reduce the number of manual reviews and points out cases that need quick attention.<\/p>\n
AI supports, but does not replace, human judgment. CMS says licensed doctors make the final call on coverage. This lowers the risk of wrong denials that can happen if only AI makes decisions.<\/p>\n
However, some worry that human reviews after AI screening might be too fast and not thorough. Some reports say insurance doctors spend under two seconds on prior authorizations. Providers should watch for this and make sure there are good appeal processes.<\/p>\n
Electronic prior authorization systems based on HL7\u00ae Da Vinci FHIR\u00ae standards automate many steps. These systems let payers and providers exchange information in real time. They handle request submissions, needed documents, status updates, and decision notices.<\/p>\n
IT managers in medical practices should try to use interoperable, EHR-integrated PA tools. Tools that work with SMART on FHIR\u00ae apps let providers see authorization rules inside their normal software. This reduces workflow problems.<\/p>\n
Even with benefits, providers and payers face challenges to put in these technologies. They must coordinate well across teams, including provider communications, EHR data sharing, claims processing, and rule monitoring.<\/p>\n
Setting up these systems can take 8 to 18 months depending on how complex the organization is. Early planning and teamwork are important to meet CMS deadlines and avoid disruptions.<\/p>\n
Practice managers and owners in the affected states should take these steps to handle the new prior authorization changes:<\/p>\n
Providers outside these states should watch the WISeR Model effects. Since CMS may expand after 2031, starting early with new tech and processes can help long-term operations.<\/p>\n
Starting in 2026, Traditional Medicare will add prior authorization rules under the WISeR Model. This is a big change for healthcare providers. It aims to stop Medicare fraud and make sure costly services are used properly. But it also may cause more work and possible delays in patient care.<\/p>\n
New AI tools and workflow automation could help reduce these problems and make the process smoother.<\/p>\n
Practice managers, owners, and IT staff must get ready to keep things running well and protect patient care. Early training, better documentation, technology use, and careful monitoring will help providers handle these prior authorization changes while supporting patient and practice needs.<\/p>\n Starting January 1, 2026, CMS will implement prior authorization requirements for certain traditional fee-for-service Medicare services in six states, aiming to reduce unnecessary or inappropriate care and save federal funds.<\/p>\n<\/p><\/div>\n<\/details>\n The six states are New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington, where the Wasteful and Inappropriate Service Reduction (WISeR) Model will be tested.<\/p>\n<\/p><\/div>\n<\/details>\n The WISeR Model uses enhanced technologies like AI and machine learning to reduce wasteful or low-value Medicare services vulnerable to fraud, waste, and abuse, with final authorization decisions made by licensed clinicians.<\/p>\n<\/p><\/div>\n<\/details>\n No, AI supports the review process, but licensed clinicians make the final authorization decisions to ensure coverage compliance.<\/p>\n<\/p><\/div>\n<\/details>\n Inpatient-only services, emergency services, and services posing a substantial risk to patients if delayed are explicitly excluded.<\/p>\n<\/p><\/div>\n<\/details>\n Yes, providers can either submit prior authorization requests for selected services or go through post-service\/pre-payment medical reviews.<\/p>\n<\/p><\/div>\n<\/details>\n Seventeen services vulnerable to fraud and abuse will require prior authorization, including nerve stimulators, certain spinal procedures, wound care treatments, and others prone to waste or inappropriate use.<\/p>\n<\/p><\/div>\n<\/details>\n Critics from both political sides argue it may introduce delays and administrative burdens, questioning AI’s effectiveness and the addition of a new third-party in the review process.<\/p>\n<\/p><\/div>\n<\/details>\n Traditional Medicare generally requires prior authorization for fewer services, mainly some outpatient services and durable medical equipment, whereas nearly all Medicare Advantage enrollees face prior authorization for various higher-cost services.<\/p>\n<\/p><\/div>\n<\/details>\n The 2025 National Health Care Fraud Takedown resulted in charges against over 300 defendants for schemes targeting Medicare, underscoring CMS\u2019s intensified efforts using models like WISeR to prevent fraud and abuse.<\/p>\n<\/p><\/div>\n<\/details><\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":" Prior authorization means doctors must get approval from the insurer before giving some services, tests, or medicines to patients.
