Prior authorization remains one of healthcare's most persistent administrative bottlenecks, with physicians and their staff spending an average of 13 hours per week completing authorization requests, according to the 2024 AMA Prior Authorization Physician Survey. The process has evolved from fax machines and phone calls to electronic prior authorization (ePA) solutions, yet significant manual burden persists even with digital tools in place.

Think of this evolution as a spectrum: manual PA sits at one end, where every request requires phone calls, faxes, and paper forms. Electronic prior authorization represents meaningful progress by digitizing the transmission of many of those requests. But on the far end sits full automation, which eliminates manual workflow steps entirely. Understanding where ePA delivers value, and where it falls short, is critical for healthcare organizations seeking to reclaim administrative hours and improve patient access to care.

Understanding the Manual PA Process

The traditional PA workflow relies on fax machines, phone calls and paper forms, creating friction at every step of the process. Understanding this baseline helps contextualize why electronic solutions emerged and why they haven't fully solved the problem.

How Manual PA Works

The manual PA journey typically begins after a prescription has already been written. A provider writes a prescription, which gets sent to the pharmacy, often following a manual step of signing off on the prescription by the provider’s team. The pharmacist submits a claim to the payer, receives a rejection indicating prior authorization is required and then must contact the prescriber's office via phone or fax to initiate the authorization process.

From there, the prescriber's staff locates the appropriate PA form (which varies by payer and drug), gathers the necessary clinical documentation from the patient's medical record, manually populates the form fields and submits everything via fax or payer web portal. Staff then wait for a response, often following up by phone when updates don't arrive.

According to Tomorrow Health and CAQH research, approximately 67% of PAs remain fully or partially manual, even in practices with electronic tools available. This reflects the complexity of integrating PA workflows into clinical operations.

The True Cost of Manual Processes

The healthcare industry spends an estimated $35 billion annually on PA processing. For individual practices, manual PA transactions cost approximately $10.97 per transaction in direct staff time, per the 2023 CAQH Index Report.

The 2024 AMA survey found that 82% of physicians listed prior authorization as time-consuming, with one-third reporting they have less face-to-face patient time as a result. Perhaps most telling: 40% of physicians now have staff working exclusively on prior authorization, according to the AMA.

Impact on Patient Medication Access

Manual PA delays directly affect patient outcomes in measurable ways. According to research published in the Journal of Managed Care & Specialty Pharmacy, prescription abandonment rates range from 37% to 78% depending on medication category and delay duration.

The consequences extend beyond delayed access: when patients don't receive timely access to prescribed medications, untreated conditions may worsen, leading to additional healthcare utilization and costs that offset any savings from the PA process itself.

For patients with chronic conditions, PA delays can interrupt established treatment regimens, potentially leading to disease progression, symptom flares, or complications that require more intensive intervention. For patients with acute conditions, delays can mean prolonged suffering, missed work, and in some cases, escalation to emergency care.

The clinical and financial ripple effects of PA delays illustrate why improving the process isn't just an administrative priority; it's a patient care imperative that affects outcomes across the healthcare continuum.

How Electronic Prior Authorization Works

Electronic prior authorization changes the workflow by integrating authorization directly into the prescriber's EHR system, creating a standardized digital pathway that replaces phone calls and faxes with electronic transactions.

The Technical Workflow

The ePA process follows the NCPDP SCRIPT standard, which was formally added as a standard in 2013. In theory, this creates a structured electronic workflow. In practice, the process typically begins reactively, rather than proactively:

1. Prescription sent to pharmacy: Provider writes a prescription and transmits it to the pharmacy
   
   

2. Claim rejection: The pharmacy submits a claim to the payer, which returns a rejection code indicating PA is required
   
   

3. Provider notification: The pharmacy initiates a PA request and the provider's office is notified, often via fax
   
   

4. Question set delivery: Payer-specific questions are delivered electronically to the provider (once staff manually enter the request into their system)
   
   

5. Form population and submission: Staff gather clinical documentation, complete required fields, and submit
   
   

6. Payer processing: The payer processes the request electronically
   
   

7. Determination returned: The decision is sent back to the provider's system

Staff often must still manually locate and enter clinical documentation to complete the form. Steps 4-5 (question set delivery, form population, and submission) still require significant manual effort in most ePA implementations, as well as the manual effort to retroactively kick off the process following a reject code, and the manual effort in following up when a determination is not received.

Integration Points and Platforms

The ePA landscape includes two broad categories of solutions: platforms that digitize transmission (such as CoverMyMeds and Surescripts) and automation platforms that eliminate manual workflow steps at the same time as digitizing the transmission (such as Develop Health).

Major ePA platforms integrate with EHR systems in different ways. Some offer EHR-embedded solutions that work within the provider's existing workflow, while others provide web-based portals that exist outside the clinical system.

According to CVS Caremark, ePA is 2-3 times faster than phone/fax for receiving decisions, with 62% of ePA requests receiving determinations within two hours.

The Reality of "Electronic" PA: A Fax in the Workflow

Here's what the ePA process often looks like in practice: The pharmacy receives a rejection code and initiates a prior authorization request. How does the provider's office find out? In many cases, they receive a fax.

A physical fax arrives at the practice or an e-fax lands in an inbox. Staff must then print the fax, manually read the details and type information from that fax (such as a PA request code) into their EHR or ePA portal to access the payer's question set. Only then can they begin completing the authorization.

The process is electronic to a certain extent, but manual handoffs, paper documents, and data re-entry persist at critical junctures.

What ePA Does and Doesn't Automate

ePA digitizes the transmission of PA requests, which is valuable, but it leaves the underlying workflow largely intact.

What ePA automates:

• Electronic transmission of the request
  
  

• Delivery of payer-specific question sets
  
  

• Return of the coverage determination

What ePA doesn't automate:

• Staff must still await the rejection from the pharmacy
  
  

• Pharmacy staff still need to kick off the PA
  
  

• Staff still receive an empty form
  
  

• Staff must locate clinical documentation in the EHR
  
  

• Staff must manually populate form fields with clinical data
  
  

• Staff must monitor for responses and call PBMs when updates don't arrive
  
  

• The request still sits in multiple queues before reaching a determination

This means that even with ePA in place, significant manual work persists. The request sits in fewer queues and moves faster once submitted, but the pre-submission burden remains substantial.

And this describes the ideal ePA process, when everything works as designed. In practice, many PA requests don't follow this smooth electronic pathway. System incompatibilities, payer-specific portal requirements and workflow gaps mean that a significant portion of "electronic" prior authorizations still involve manual workarounds, phone calls to resolve issues or fallback to fax when the electronic channel fails.

Beyond ePA: Full PA Automation

The difference between ePA and full automation is significant. ePA is like switching from mailing a letter to making a phone call, faster transmission, but someone still needs to make the call. Full automation is the call happening automatically, with no human intervention required for routine authorizations.

Where ePA Falls Short

Despite its advantages over manual processes, ePA leaves several critical gaps:

Pre-submission burden: Staff still spend 20-30 minutes per authorization gathering clinical documentation, filling out forms, and navigating portal interfaces. This time investment occurs before the PA is even submitted.

Queue-based delays: Even electronic submissions sit in queues waiting for manual retrieval and review. The transmission is faster, but processing time varies.

Follow-up burden: Providers must frequently call PBMs to check status when responses don't arrive within expected timeframes. This tracking and follow-up work adds to the administrative load.

Reactive initiation: 60% of medical practices report that they only initiate PA requests when they’re made aware of the need for PA by the dispensing pharmacy. This reactive approach means delays are built into the process from the start.

"You still need to be handling the PA multiple times. It still sits in a queue multiple times." The digital infrastructure improves, but the workflow burden persists.

How Full Automation Addresses the Gaps

Full PA automation takes a fundamentally different approach by eliminating manual steps entirely:

• Proactive identification: Determines PA requirements before pharmacy rejection, at the point of prescribing
  
  

• Automatic documentation: Pulls clinical documentation from the EHR without staff intervention
  
  

• Instant form population: Populates and submits forms in seconds, not hours or days
  
  

• Continuous monitoring: Tracks responses automatically and follows up when needed
  
  

• Pre-submission compression: Compresses pre-submission time from days to seconds

The distinction matters most in the time before submission. When people talk about medication access speed, how quickly you get to the submission is critical. That's where it can still take many days for the provider's office with ePA. Full automation can accomplish this in seconds.

The Time That Matters Most

Providers lose significant time during two phases: pre-submission (kicking off the PA, gathering documentation, completing forms) and post-submission (tracking, following up, calling payers). While ePA improves post-submission speed, full automation addresses both phases.

For a practice completing 43 prior authorizations weekly per physician, even small per-PA time savings compound into significant labor recapture. If automation saves 20 minutes per PA, that's over 14 hours per physician per week, time that can be redirected to patient care.

Comparing Manual PA, ePA, and Full Automation

The performance differences across PA methods are well-documented, though understanding the nuances requires looking beyond headline metrics.

Speed to Submission vs. Speed to Decision

It's important to distinguish between two different time metrics when evaluating PA solutions:

Speed to submission measures the time from prescription to PA submission. This is where full automation delivers the greatest gains, compressing days of staff work into seconds. ePA alone doesn't significantly improve this metric because the manual pre-submission work remains.

Speed to decision measures the time from PA submission to payer determination. This metric improves dramatically with ePA and full automation versus manual processes, the analysis from North Dakota Legislative found median decision time decreased 69% with ePA (from 18.7 hours to 5.7 hours).

When measuring PA performance, most benchmarks focus on post-submission decision time. But for providers and patients, the days lost before submission often matter more and ePA alone doesn't address this gap.

Impact on Medication Access and Adherence

Lower PA turnaround correlates directly with higher likelihood of medications being dispensed and picked up. According to research from the Journal of Clinical Oncology, introducing a new prior authorization policy increased odds of medication discontinuation by 7.1 times and increased time to next fill by nearly 10 days.

The AMA survey data paints a concerning picture: 94% of physicians report PA leads to care delays and 78% report it sometimes or often leads to treatment abandonment.

Phone/fax submission can delay dispensing by a full day or more compared to electronic submission, according to CAQH analysis. But even with ePA, delays in initiating the PA (gathering documentation, completing forms) can add days before submission occurs.

Administrative Burden Reduction

ePA does reduce some administrative burden versus fax/phone: fewer system toggles, digital transmission, EHR integration, and elimination of fax-related tasks.

However, significant manual work persists with ePA:

• Staff still spend 20-30 minutes per authorization gathering clinical documentation
  
  

• Staff must manually populate form fields with clinical data
  
  

• Staff must monitor for responses and call PBMs when updates don't arrive

According to CAQH, prior authorization remains one of the costliest administrative transactions even as electronic adoption grows. Full automation eliminates these residual manual steps by auto-populating forms from EHR data, submitting without staff intervention, and monitoring responses automatically.

Cost Comparison Across Methods

Sources: CAQH 2023 Index Report, MACPAC Prior Authorization Report

Manual PA costs providers approximately $11-13 per transaction in direct staff time. ePA reduces transmission costs but doesn't eliminate documentation and follow-up labor. The hidden cost of ePA is that staff time spent on pre-submission and post-submission work rarely appears in transaction-level comparisons.

Full automation reduces per-PA cost to near-zero for routine authorizations by eliminating staff involvement entirely. At 40+ PAs per physician per week, even small per-transaction savings compound into significant labor recapture.

Barriers to Full Automation Adoption

Despite clear benefits, adoption of full automation remains incomplete. Understanding these barriers helps organizations plan realistic implementation strategies.

The ePA Plateau

Many organizations have adopted ePA but stopped there, assuming the problem is solved. This "ePA plateau" reflects several factors:

• ePA vendors positioned electronic transmission as the end state, creating market messaging that conflated "electronic" with "automated"
  
  

• Meaningful improvements over manual processes created satisfaction with partial solutions, going from fax to electronic submission feels like significant progress
  
  

• True automation requires going beyond transmission to eliminate manual pre-submission and post-submission work, which demands additional investment
  
  

• Staff have adapted their workflows to accommodate remaining manual steps, normalizing inefficiency
  
  

• Metrics often focus on submission speed rather than total PA handling time, masking the burden that persists

The result is complacency: organizations check the "electronic PA" box without achieving the full efficiency gains that automation offers. Leadership may believe the PA problem is solved while frontline staff continue struggling with documentation gathering, form completion, and response monitoring.

Breaking through the ePA plateau requires honest assessment of current workflows, recognition that electronic transmission is necessary but insufficient, and commitment to eliminating manual steps that ePA leaves in place.

The Reactive vs. Prospective Challenge

The gap between reactive and prospective PA initiation represents a significant efficiency opportunity. As noted, 71% of PA requests are initiated at the pharmacy after a rejected claim, while only 17% of providers start PA at the point of prescribing.

Reactive PA reduces efficiency gains even with electronic submission because the delay has already occurred. The patient has already left the office, the pharmacy has already rejected the claim, and staff must now respond to an external trigger rather than proactively managing the process.

Full automation addresses this by determining PA requirements at the point of prescribing, before the prescription ever reaches the pharmacy.

Process Complexity and Variability

Variability across payers, drug categories, and benefit types creates complexity that limits automation:

• 28% of providers revert to non-electronic methods for complex prescription situations
  
  

• 20% automatically use non-electronic methods when unsure if ePA is available
  
  

• 19% choose manual submission for specialty medications due to complexity

This variability means that even organizations committed to electronic processes maintain parallel manual workflows for edge cases, limiting overall efficiency gains.

Regulatory Drivers for PA Modernization

Federal policy is accelerating the shift toward electronic and automated PA, setting standards for digital transmission, response times, and transparency.

CMS Interoperability and Prior Authorization Final Rule

The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F), finalized in January 2024, establishes significant requirements for impacted payers:

API Requirements (January 1, 2027):

• FHIR-based Prior Authorization API required
  
  

• Must support full PA workflows: discovery, submission, tracking, and determination
  
  

• Must expose documentation requirements electronically

Response Time Standards (January 1, 2026):

• 72 hours for urgent/expedited requests
  
  

• 7 calendar days for standard requests

Transparency Requirements (January 1, 2026):

• Payers must provide specific denial reasons
  
  

• Annual reporting of PA metrics required

What the Rule Addresses: Standardized digital infrastructure, faster required response times, greater transparency into PA decisions.

What the Rule Doesn't Address: Pre-submission burden on providers, manual work required even with compliant ePA systems, follow-up burden when payers don't respond timely, proactive PA identification at point of prescribing.

Regulatory compliance ensures the pipes are electronic, but doesn't guarantee the workflow is automated. Providers meeting CMS requirements may still face significant manual PA burden.

State-Level PA Reform

State legislatures continue advancing PA reform with increasing momentum. According to the AMA, 10 states have enacted prior authorization reform bills in 2024 alone.

State reforms increasingly address:

• Response time limits (often 72 hours urgent, 5-7 days standard)
  
  

• Approval duration requirements for chronic conditions
  
  

• Gold-carding provisions exempting high-approval providers
  
  

• Automatic approval renewal for established therapies

However, state rules vary widely, creating compliance complexity for multi-state providers. Full automation can help manage state-by-state variation by applying appropriate rules automatically based on patient coverage.

Provider Incentives

The CMS rule adds new provider incentives through the Merit-based Incentive Payment System (MIPS). A new Electronic Prior Authorization measure for MIPS-eligible clinicians under the Promoting Interoperability category rewards electronic submission.

However, current incentives reward adopting ePA infrastructure, not optimizing PA workflows. Providers can meet regulatory requirements while still spending 20+ minutes per PA on manual tasks. As PA volume grows, meeting ePA requirements alone won't address administrative burden.

Forward-looking organizations are investing in automation beyond regulatory minimums to recapture staff time and improve patient access.

The Regulatory Floor vs. Operational Excellence

CMS requirements establish a floor for PA digitization, not a ceiling. Compliance ensures payers accept electronic submissions and respond within set timeframes. This is meaningful progress, it creates infrastructure that didn't exist before and establishes accountability that was absent.

But compliance doesn't address:

• How quickly providers can prepare submissions
  
  

• How much staff time each PA consumes
  
  

• Whether PA requirements are identified proactively or after pharmacy rejection
  
  

• The time and cognitive burden on staff who manage multiple PA workflows simultaneously
  
  

• The downstream effects on patient care when staff are overwhelmed with administrative tasks

The distinction between regulatory compliance and operational excellence is critical. An organization can be fully compliant with CMS-0057-F requirements while still experiencing significant PA-related burden. Staff may still spend 20+ minutes per authorization gathering documentation, even when the submission itself takes seconds.

Organizations that treat ePA compliance as the end state will continue to struggle with PA burden, high staff turnover in administrative roles, and delayed patient access to medications. Those that build full automation on top of compliant infrastructure will capture the efficiency gains that regulations alone can't deliver, creating competitive advantage through superior operational performance.

Best Practices for Moving Beyond ePA

Organizations seeking to maximize efficiency should evaluate their current state honestly and implement targeted improvements. The path from ePA to full automation isn't instantaneous, it requires systematic assessment, strategic investment, and operational commitment.

Evaluate Your Current ePA Reality

Start by measuring actual performance, not assumed performance. Many organizations believe their PA process is "electronic" without understanding how much manual work persists beneath the surface:

• Track staff time spent on PA activities, even with ePA tools in place
  
  

• Identify where manual work persists: documentation gathering, form population, follow-up calls
  
  

• Measure pre-submission time separately from post-submission time
  
  

• Calculate true cost per PA including all labor, not just transaction fees

Many organizations discover that their "electronic" PA process still involves substantial manual effort that doesn't appear in standard metrics.

Leverage Automation Capabilities

When evaluating PA solutions, distinguish between ePA features and true automation features:

ePA features (transmission-focused):

• Electronic submission to payers
  
  

• Digital question set delivery
  
  

• EHR integration for submission

Automation features (workflow-focused):

• Automatic documentation gathering from EHR
  
  

• Proactive PA identification at point of prescribing
  
  

• Auto-population of form fields with clinical data
  
  

• Automated response monitoring and follow-up

Prioritize solutions that automate pre-submission work, not just transmission.

Monitor and Optimize

Establish ongoing metrics to track improvement:

• PA turnaround times by payer and drug category
  
  

• Denial rates and common denial reasons
  
  

• Ratio of prospective to reactive PA submissions
  
  

• Staff time spent on PA activities (before and after automation)
  
  

• Patient medication access speed from prescription to fill

Regular monitoring identifies optimization opportunities and demonstrates ROI from automation investments.

Frequently Asked Questions

What is electronic prior authorization (ePA)? 

Electronic prior authorization is a digital process that allows providers to submit PA requests electronically through their EHR system rather than using phone calls, faxes, or paper forms. The NCPDP SCRIPT standard enables standardized electronic exchange of PA information between prescribers and payers, reducing transmission time and improving tracking capabilities.

How much faster is ePA compared to manual prior authorization? 

According to North Dakota Legislative, ePA reduces median decision time by 69%, from 18.7 hours to 5.7 hours. However, this measures post-submission time only. Pre-submission work (documentation gathering, form completion) can still take hours or days with ePA, which is why full automation offers additional efficiency gains.

What is the difference between ePA and full PA automation? 

ePA digitizes the transmission of PA requests but leaves the pre-submission and post-submission workflows largely manual. Staff still gather documentation, populate forms, monitor for responses and call PBMs when updates don't arrive. Full automation eliminates these manual steps by automatically pulling clinical data from the EHR, populating forms, and submitting requests without staff intervention.

When do CMS prior authorization requirements take effect? 

The CMS Interoperability and Prior Authorization Final Rule requires impacted payers to implement response time standards (72 hours urgent, 7 days standard) and transparency requirements by January 1, 2026. FHIR-based Prior Authorization APIs must be operational by January 1, 2027. These requirements apply to Medicare Advantage, Medicaid/CHIP, and Qualified Health Plan issuers.

How much does prior authorization cost healthcare organizations? 

Manual PA transactions cost providers approximately $10-13 per transaction according to CAQH, while electronic transactions cost approximately $4-6. At the industry level, PA processing costs an estimated $35 billion annually, according to Health Affairs research.

What percentage of prior authorizations are still manual? 

Despite widespread ePA availability, approximately 67% of PA volume still remains fully or partially manual. The 2024 CAQH Index reports only 35% of medical industry prior authorizations are conducted fully electronically using the X12 278 standard.
