Prior authorization has long been one of the most frustrating aspects of Medicare Advantage, but heading into the 2026 plan year, seniors and providers are reporting longer wait times than in previous years. These delays are increasing even as federal regulators prepare to enforce new rules that, in theory, should make the process faster.
Here's what's driving the slowdown, what the 2026 rules actually require, and what Medicare Advantage enrollees can do to protect themselves.
Why Prior Authorization Delays Are Increasing Before 2026
A combination of operational, regulatory, and staffing pressures is pushing wait times higher:
1. More prior authorization requests overall
Utilization of imaging, specialty care, and durable medical equipment continues to rise, increasing the total volume plans must review.
2. Staffing shortages inside Medicare Advantage plans
Clinical review teams at several large insurers are understaffed, leading to slower processing of both standard and urgent requests.
3. Stricter utilization review policies
In response to upcoming payment changes and regulatory requirements, many plans are narrowing networks or adding new documentation requirements, which increases the number of authorizations required for routine care.
4. Administrative restructuring tied to new 2026 federal requirements
A policy briefing from Applied Policy notes that Medicare Advantage plans are overhauling their internal authorization workflows ahead of mandatory 2026 transparency reporting—creating temporary slowdowns as systems are rebuilt.
Applied Policy: Prior Authorization in Medicare Advantage BriefingWhat the 2026 CMS Rules Require
In January 2024, the Centers for Medicare & Medicaid Services (CMS) finalized a major rule designed to speed up prior authorization decisions across Medicare Advantage and other health plans.
Beginning January 1, 2026, Medicare Advantage plans must:
- ✓Issue urgent decisions within 72 hours
- ✓Issue standard decisions within 7 calendar days
- ✓Adopt digital prior authorization through standardized APIs
- ✓Publicly report approval rates, denial rates, and average decision times
Myers & Stauffer published an implementation timeline confirming that these requirements become enforceable starting in 2026, with additional technology mandates taking effect in later phases.
If Rules Are Tightening, Why Are Delays Getting Worse?
Even with stronger regulations on the horizon, delays are increasing because:
1. Many plans still rely on manual review systems
Fax-based submissions, manual documentation checks, and fragmented internal processes create bottlenecks.
2. Required technology is still being built
The CMS rule mandates digital authorization systems that many insurers have not yet completed.
3. Documentation issues remain widespread
Missing clinical notes, incomplete diagnosis codes, or inconsistent provider documentation can pause a request indefinitely.
4. Prior authorization delays extend beyond Medicare Advantage
The National Conference of State Legislatures (NCSL) highlights that prior authorization is one of the most common causes of delayed or forgone care across many insurance types—not just MA plans.

Temporary slowdowns during system upgrades
As plans restructure their review processes, approval times may worsen before they improve.
More scrutiny of high-cost services
Cardiology, oncology, orthopedics, pain management, and high-end imaging are expected to remain the most heavily reviewed categories.
Potential improvements later in 2026
As digital authorization systems mature, turnaround times may improve—though the pace will vary between insurers.
Increased transparency
For the first time, Medicare Advantage plans will be required to publish their authorization metrics, creating public accountability for delays and denials.
How Seniors Can Reduce Prior Authorization Delays
While no strategy guarantees faster approval, experts recommend these steps:
Action Steps:
- Ensure providers submit complete documentation upfront — Missing diagnosis codes and chart notes are the biggest sources of delays.
- Request the clinical criteria your plan uses — Medicare Advantage plans must provide these criteria upon request.
- Follow up every 2–3 days — Many pending requests are simply waiting for additional information from providers.
- Ask if the request qualifies as urgent — Urgent requests must be reviewed within 72 hours under CMS rules.
- Use your plan's digital submission portal — Online submissions are generally faster than faxed paperwork.
- File a grievance if delays become excessive — A grievance requires the plan to evaluate whether it is meeting CMS timeliness requirements.
When to Consider Switching Medicare Advantage Plans
If your current plan:
- frequently delays authorization requests,
- has a narrow specialist network,
- requires excessive documentation, or
- offers inconsistent customer service,
…it may be wise to review alternatives during the next Annual Enrollment Period.
The Bottom Line
Prior authorization delays are rising at the same time that CMS is tightening oversight. Seniors should expect:
- longer wait times early in 2026,
- stricter documentation requirements,
- more frustration in the short term, and
- greater transparency later in the year.
Understanding the new rules—and knowing how to navigate them—will help Medicare Advantage enrollees maintain access to timely care during this transition period.
