‍How to Centralize Prior Authorization – And Why Health Systems Are Making the Move

Most health systems didn't set out to build a fragmented prior authorization operation. It happened organically– specialty by specialty, department by department, each team solving the immediate problem in front of them. The result is a patchwork that's difficult to manage, harder to improve, and nearly impossible to scale. Centralizing prior authorization is the fix and it's harder than it looks, which is exactly why so many organizations stall before they see results.

‍

The Hidden Cost of Decentralized Prior Authorization

‍

When prior authorization is managed department by department, the problems compound quietly: workflows aren't shared, payer knowledge stays siloed, staff in one service line develop institutional expertise about what a specific payer requires for a specific procedure– and none of it transfers.

The financial exposure that follows is significant. Up to 12% of hospital revenue can be at risk due to denied claims, with prior authorization issues ranking among the leading causes. And the operational cost of chasing those denials– reworking cases, managing appeals, tracking statuses across disconnected systems– is often invisible precisely because it's distributed across so many teams.

Without cross-organizational visibility, improvement efforts have no real foundation. Denial rates vary by payer, by service line, by provider, and by procedure type– but when prior authorization is managed in silos, the patterns that explain those variations never surface. Leadership can see that something is wrong. Diagnosing where, and why, is another matter.

Why Centralizing Prior Authorization Changes the Picture

‍

What a centralized prior authorization operating model actually unlocks is organizational intelligence. Fragmented, disconnected workflows and systems are a leading cause of denials and write-offs for major health systems. When authorization data flows through a single operational layer, the patterns that were previously invisible become actionable. Which payers are driving the most friction on which procedure types, which providers have elevated peer-to-peer rates that signal a documentation education opportunity, and where write-off exposure is concentrated and why.

That visibility is the foundation for continuous improvement in a way that departmental prior authorization management simply can't support. When revenue cycle owns or oversees the prior authorization function, the feedback loops close faster, and what's learned from one denial informs the next submission, across the whole organization.

Departments benefit, too. When the routine authorization workload (requirements checking, clinical bundling, submission, statusing) is handled through centralized automation, departmental staff shift away from administrative processing and back toward patient-facing work. A centralized prior authorization model done well doesn't reduce clinical involvement; it removes the administrative overhead that was never a good use of clinical time to begin with.

How to Centralize Prior Authorization: A Four-Phase Framework

Centralizing prior authorization is a progression. Most health systems will move through it in stages, and the sequence is important to the success.

• Phase 1: Establish visibility. Before centralizing ownership or restructuring workflow, organizations need a clear picture of what's actually happening across their prior authorization footprint: denial rates by payer and service line, submission volumes, peer-to-peer rates, write-off exposure. That baseline provides the necessary foundation to prioritize where centralization will have the greatest immediate impact. 

• Phase 2: Standardize the workflow layer. A prior authorization solution that operates consistently across departments and specialties, rather than maintaining separate tools and processes per service line, is the structural prerequisite for everything that follows. EHR-native integration matters here; when staff can manage authorizations without leaving their primary workflow, adoption follows and data quality improves with it. This is also the stage where the organizational work begins in earnest – standardizing workflows across departments means navigating competing ownership interests, and that requires early stakeholder and resource allocation alignment.

• Phase 3: Centralize intelligence. Centralized payer policy retrieval refreshed daily, clinical bundling logic – matched to policy criteria – that improves with volume and feedback, analytics that surface patterns across the full organization. At this stage, revenue cycle has the operational visibility to manage prior authorization strategically, and departments have the automation coverage to focus on what they do best.
• Phase 4: Shift ownership to revenue cycle. As automation carries the routine load and the remaining case volume becomes genuinely exception-based, revenue cycle takes ownership of the prior authorization function. The target state of centralization is a team with shared ownership, responsibility, and accountability for prior authorization across the board, managing volume with human judgement where it’s needed and technology where it’s not.

What Makes It Hard

‍

None of this happens cleanly. The operational complexity is real: centralizing a meaningful share of prior authorization volume at a sizable health system means building a team, which typically requires a staffing analysis, new job descriptions, market recruiting, onboarding, and cross-specialty training for staff who may not have experience across every service line. That's before accounting for the political dimension. Departments that have managed their own prior authorization workflows often resist giving up that ownership— not unreasonably. They've built institutional knowledge, they've hired for it, and they're not always confident that a centralized function will handle their cases with the same care. That friction is normal, and ignoring it in the planning process is one of the most common reasons centralization efforts stall. Getting buy-in at the department level, early, is as important as getting the technology right.

‍

The Role Technology Plays

‍

None of these phases move at any meaningful speed without the right technology underneath them. As of 2024, only 35% of medical plans had fully electronic prior authorization processes, which means most health systems are still operating in a mixed environment where a significant share of the prior authorization workload remains manual and staff-intensive. A centralized operation built on that foundation inherits all of that friction.

‍

When the technology layer is right (payer connectivity at depth, EHR-native integration, policy retrieval that refreshes daily, clinical bundling logic that learns across volume) centralization becomes operationally viable rather than just a management aspiration. The routine cases move without staff involvement. What remains is an exception-based workload that a centralized team can actually manage. And because all of that activity is flowing through a single infrastructure, the analytics that emerge are organizational and actionable. That's the difference between knowing your overall denial rate and knowing exactly which payer, procedure type, and documentation gap is driving it.

‍

Here's where most centralization efforts go sideways. Organizations approach it as either a staffing consolidation (pull all prior authorization staff into a central team) or a vendor decision (pick one tool and hope it works everywhere). Neither gets at the real opportunity.

‍

Real centralization is an infrastructure question. It's about building one workflow layer, one data layer, and one source of truth that spans specialties, sites, and operating models. Departments can still be involved in authorization. What changes is where the intelligence and accountability live.

‍

Technology is what makes centralization scale.

Centralized Prior Authorization Is a Competitive Advantage

‍

PA volume continues to increase, and the regulatory environment is adding requirements faster than most organizations can absorb them. Federal rules taking effect through 2026 and 2027 will mandate faster payer decision timelines, new electronic submission standards, and expanded data sharing requirements. Health systems that have already built a centralized prior authorization infrastructure will adopt those changes faster and capture the benefit earlier.

‍

The organizations still managing prior authorization as a departmental function will absorb those changes as additional coordination overhead on top of an already fragmented operation.

‍

Centralizing prior authorization is how health systems stop solving the same problem repeatedly, in every corner of the organization, and start solving it once, in a way that compounds over time.
