Prior Authorization in Healthcare: Understanding the Ongoing Challenges for Physicians in 2026

Prior authorization remains one of the most significant hurdles in healthcare delivery today. Despite regulatory efforts like the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) rolling out in 2026, physicians and medical practices continue to face substantial delays and administrative burdens. These challenges affect not only healthcare providers but also the patients who rely on timely access to necessary treatments.

The Scale of Prior Authorization Requests in 2024

Data from 2024 highlights the massive volume of prior authorization requests handled by Medicare Advantage plans. Nearly 53 million requests were processed, with insurers denying about 7.7% of them. This means over 4.1 million requests were rejected, often for treatments physicians considered medically necessary.

These denials cause significant delays in care. Patients may abandon treatment plans or experience worsened health outcomes due to the wait times and uncertainty. The high denial rate also forces physicians and their staff to spend countless hours on paperwork, appeals, and resubmissions.

Impact on Physicians and Medical Practices

Physicians report that prior authorization is a major source of frustration and burnout. According to the American Medical Association's 2024 survey, 93% of physicians say prior authorization delays patient care, and 89% link it to increased burnout.

Medical practices often complete dozens of prior authorization requests per physician each week. Staff members dedicate hours every day to managing these requests, which diverts time and attention away from direct patient care. This administrative burden contributes to stress and reduces overall efficiency in healthcare delivery.

Challenges with Specialty and High-Cost Medications

Certain medications, especially high-cost or specialty drugs like GLP-1 agonists used for diabetes and obesity, face even more stringent prior authorization requirements. These medications often require extensive documentation and justification before insurers approve coverage.

The extra barriers delay patient access to these important treatments, which can negatively affect disease management and patient outcomes. Physicians must navigate complex insurer policies while advocating for their patients, adding to the workload and frustration.

The CMS Interoperability and Prior Authorization Final Rule

The CMS Interoperability and Prior Authorization Final Rule aims to improve the prior authorization process by increasing transparency and data exchange between providers and payers. Starting in 2026, this rule requires insurers to use standardized electronic prior authorization transactions.

While this change promises to reduce paperwork and speed up approvals, many physicians remain skeptical about its immediate impact. The transition to electronic systems will take time, and the underlying issues of denials and administrative complexity may persist.

Practical Steps for Physicians and Practices

Physicians and medical groups can take several steps to manage prior authorization challenges more effectively:

• Invest in technology that supports electronic prior authorization submissions to reduce manual paperwork.

• Train staff on insurer requirements and documentation standards to improve approval rates.

• Track denials and appeals to identify patterns and target efforts for improvement.

• Advocate for policy changes by sharing experiences with professional organizations and regulators.

• Communicate clearly with patients about potential delays and what to expect during the authorization process.

  
  

These strategies can help reduce the time spent on prior authorization and improve patient care continuity.

Looking Ahead

Prior authorization will remain a significant barrier to care in 2026 and beyond. Although regulatory efforts like the CMS rule offer hope for improvement, the reality on the ground is that physicians and their teams will continue to face administrative challenges.

The key takeaway for healthcare providers is to prepare for ongoing changes while adopting practical solutions to manage prior authorization demands. By doing so, they can protect valuable time for patient care and reduce the stress associated with insurer requirements.

Patients and providers alike benefit when prior authorization processes become more efficient and transparent. Until then, understanding the scope of the problem and actively addressing it remains essential for improving healthcare delivery.
