In 2025, physicians nationwide submit 45 prior authorization requests per week on average, with staff spending nearly 14 hours weekly just on approvals, according to the American Medical Association (AMA) [AMA, 2025]. That’s the prior authorization bottleneck: patients wait, care is delayed, and healthcare organizations lose revenue.
Why Prior Authorization Exists
Prior authorization (PA) was originally designed as a payer utilization management tool, ensuring clinical necessity before expensive or high-risk services are performed. The process typically involves:
- Provider submits request.
- Payer reviews documentation.
- Approval, denial, or request for additional info.
In theory, this is meant to control costs. The steps are supposed to be straightforward: request → clinical review → payer decision. Yet in practice, this becomes a slow maze. CMS requires payers to respond within 7 days for standard PA requests, and within 72 hours for expedited cases. But those timelines often aren’t met, leaving providers and patients stuck in limbo. In practice, PA has become one of the most cited administrative burdens in U.S. healthcare [Centers for Medicare & Medicaid Services, 2025].
Why Prior Authorization Persists and Why It’s Still Broken
Prior authorization (PA) was originally introduced as a payer tool to ensure clinical necessity before costly or high-risk services. But over time, what was meant to be a safeguard has become one of the most cited administrative burdens in U.S. healthcare [CMS, 2025].
Here’s what most people don’t see:
- A Shifting Purpose: Originally introduced to ensure patient safety and control costs, PA has shifted into a blunt cost-containment tool. Instead of collaboration, it now often creates friction between payers and providers.
- The Compliance Burden: While CMS sets response timelines (7 days for standard requests, 72 hours for expedited), providers report that these deadlines are frequently missed. Weeks-long delays compound across the revenue cycle—directly limiting patient access and slowing cash flow.
- Inconsistent Rules Across Payers: Every insurer applies PA differently, with unique lists, documentation requirements, and approval criteria. What’s approved in hours with one payer can take 10 days with another—draining staff time and frustrating patients.
- A Growing Risk in 2025: With CMS interoperability rules taking effect in 2026, organizations that fail to modernize workflows risk falling behind. Payers are moving toward API-driven, real-time decisions, but providers stuck in manual processes may be left at a disadvantage.
The takeaway: Prior authorization is no longer just an administrative hassle—it’s a test of organizational readiness. Providers that treat PA as a strategic priority for revenue and patient access, rather than as paperwork, will be positioned to compete more effectively.
What Changed in 2025
And while these challenges are longstanding, 2025 brought a mix of new promises, regulatory deadlines, and reality checks that show how far the industry still has to go.
- Physician Fatigue Persists: 89% of physicians reported PA-related care delays, and 25% said patients abandoned treatment due to long waits [AMA, 2025].
- Insurers Promise Reform: AHIP members pledged to reduce PA requirements and expand automation. Humana, for example, announced plans to cut 60% of its PA rules by the end of 2025 [Axios, 2025].
- Regulators Step In: CMS finalized new interoperability and electronic PA (ePA) requirements effective January 2026, mandating payers adopt FHIR-based APIs to accelerate decision-making [CMS, 2025].
- Reality Check: Despite these announcements, more than 70% of providers in a Reuters survey still face bottlenecks—citing not just payer inconsistency, but also internal staffing shortages and tech adoption gaps [Reuters, 2025].
The Patient & Financial Impact
Prior Authorization Delays
When patients face PA hurdles, care stalls. Studies show average wait times range 3–14 days, depending on payer and service [AJMC, 2025]. For oncology, imaging, and behavioral health, these delays can directly impact outcomes.
- Prior Authorization Denials: The Real Impact
- Denials aren’t just an administrative setback—they directly affect patients and revenue. In 2025, providers report that delays and denials often lead to:
- Interrupted Care: Patients face canceled or rescheduled services, which can worsen outcomes in specialties like oncology, imaging, and behavioral health.
- Treatment Abandonment: Nearly one in four patients walk away from recommended care when prior authorization takes too long [AMA, 2025].
- Financial Strain: For hospitals and clinics, each denied or delayed case adds to A/R days, increases staff rework, and results in measurable revenue leakage.
- The bigger story isn’t why denials happen—it’s the ripple effect they create: stalled care, frustrated patients, and millions in lost revenue.
Patient Access Delays & Abandonment
Nearly one in four patients abandon scheduled services when PA takes too long [AMA, 2025]. For hospitals and clinics, that translates to:
- Lost revenue from canceled services.
- Increased A/R days due to resubmissions.
- Staffing strain, as teams rework denied claims.
This bottleneck puts patient outcomes at risk and strains financial performance.
Why Automation Alone Cannot Solve Prior Authorization
2025 saw rapid adoption of electronic prior authorization (ePA) tools, but rollout is uneven. CMS’ FHIR mandate looks promising, yet real-world adoption lags due to:
- Inconsistent payer portals.
- Lack of EHR integration.
- Training gaps for staff.
Automation helps, but without governance, human review, and payer collaboration, organizations face automation bias and lingering delays. For example, an oncology clinic relying solely on AI to approve chemotherapy pre-authorization risks denial if the algorithm misses a nuanced clinical note. Human oversight remains critical. [CMS, 2025; Axios, 2025].
How Leading Organizations Are Tackling Prior Authorization Bottlenecks
Forward-thinking healthcare leaders are not waiting for 2026 mandates—they are already reshaping their PA workflows to protect both revenue and patient access. Key strategies include:
Step | Action | Real-World Impact |
1 | Front-end eligibility & benefit verification | Cuts unnecessary PA submissions by up to 20–30%, reducing downstream denials [MGMA, 2025]. |
2 | Implement electronic PA (ePA) where available | Decreases manual fax/phone follow-up, with early adopters reporting 35–40% faster approvals [CMS, 2025]. |
3 | Create dedicated PA teams or outsource to specialists | Improves turnaround times by 2–3 days and reduces staff burden by shifting low-value tasks. |
4 | Track PA turnaround times & abandoned cases | Identifies payer-specific bottlenecks; organizations that track this data reduce revenue leakage from abandoned services by 10–15% [AMA, 2025]. |
5 | Negotiate payer service-level agreements (SLAs) | Establishes accountability; providers with formal SLAs report 15% fewer delayed approvals [MGMA, 2025]. |
The insight: Success comes not from a single tool, but from treating PA as a measurable, managed workflow, where data, technology, and specialized teams combine to reduce denials and accelerate access.
