NextFin news, The Centers for Medicare & Medicaid Services (CMS) announced on Friday that beginning in January 2026, Medicare will require prior authorization for specific outpatient medical services in six states: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. This pilot program marks the first time traditional Medicare will implement pre-approval requirements similar to those common in Medicare Advantage plans.
The pilot targets approximately 17 outpatient services, including spine surgeries, steroid injections, skin and tissue substitutes, electrical nerve stimulator implants, and knee arthroscopy for osteoarthritis. CMS states the program's goal is to reduce wasteful spending, fraud, and inappropriate care by using a combination of artificial intelligence (AI) and licensed clinician reviews to determine medical necessity before approving coverage.
CMS will contract private companies to assist with the review process, employing AI tools to screen requests and identify potentially unnecessary procedures. However, final coverage decisions will be made by licensed medical professionals. CMS officials emphasize that this human oversight is intended to balance efficiency with patient safety.
The pilot program has drawn criticism from patient advocates, healthcare providers, and some lawmakers who warn that prior authorization could delay access to necessary care, especially for seniors with urgent medical needs. Critics also express concern that contractors, who share in savings from denied claims, may have financial incentives to reject more requests, potentially leading to increased denials and administrative burdens.
Frances L. Ayres, a 74-year-old retired professor from Oklahoma, expressed worry about the changes, saying, "I picked traditional Medicare to avoid the hurdles of pre-approvals. Now it looks like I may face them anyway."
CMS officials argue that the pilot will help standardize care decisions and reduce improper payments, potentially saving taxpayer dollars while maintaining quality standards. The agency plans to monitor approval and denial rates, turnaround times, patient outcomes, and financial impacts to evaluate the program's effectiveness.
Beneficiaries in the six pilot states are advised to check with their healthcare providers about whether recommended procedures require prior authorization under the new program and to prepare for possible delays in treatment approvals. CMS also encourages patients and providers to keep documentation and be aware of appeal rights if coverage is denied.
The pilot program is expected to run for multiple years, with results informing potential nationwide expansion of prior authorization requirements within traditional Medicare.
