7 Ways to Reduce Prior Authorization Turnaround Time in Your Practice

Prior authorization is the single most time-consuming administrative task in most medical practices. The average PA request takes 25-35 minutes of staff time, and the average turnaround from submission to decision is 3-7 business days for standard requests. For patients, this means delayed care. For practices, this means delayed revenue and frustrated staff.

The good news: there are concrete steps you can take to significantly reduce PA turnaround time without hiring additional staff.

1. Check PA Requirements at the Time of Scheduling

The most common reason for PA delays is discovering that authorization is needed after the patient is already on the schedule -- or worse, after the service has been performed.

What to do: Build PA requirement checks into your scheduling workflow. When a patient is scheduled for a procedure, immediately check whether that CPT code requires prior authorization for the patient's specific payer and plan.

This seems obvious, but most practices do not do it systematically. The scheduling staff schedules the appointment, and the PA team discovers the requirement days later, creating an unnecessary time crunch.

Impact: Identifying PA requirements at scheduling gives you the maximum amount of time to obtain authorization before the service date. This alone can reduce urgent and expedited PA requests by 40-60%.

2. Submit Complete Clinical Documentation on the First Attempt

Payer requests for additional information (commonly returned as denial code CO-16 or CO-252) are one of the biggest causes of PA delays. Every time the payer asks for more information, the clock resets.

What to do: For each common PA request type, create a clinical documentation checklist that includes everything the payer typically requires:

• Relevant clinical notes and history
• Diagnostic test results
• Treatment history showing previously tried alternatives
• Letter of medical necessity (for complex requests)
• Any payer-specific forms

Submit all of this with the initial request, not after the payer asks for it.

Impact: First-pass approval rates increase by 25-35% when complete documentation is submitted upfront. Each round of additional information requests adds 3-5 business days to the turnaround.

3. Use Electronic Submission Whenever Possible

Fax-based PA submission is still common, but it is the slowest method. Phone-based submission requires long hold times and introduces transcription errors.

What to do: Use the payer's electronic submission portal or an electronic PA platform wherever available. Most major payers now accept electronic PA requests, and many require them.

For payers that still require fax, use a fax confirmation system and follow up within 24 hours to confirm receipt.

Impact: Electronic submissions are typically processed 2-4 days faster than fax submissions. They also create an automatic audit trail, eliminating the "we never received it" problem.

4. Know Each Payer's Clinical Criteria

Each payer has specific clinical criteria for each procedure that requires PA. These are published in their medical policies, Local Coverage Determinations (LCDs), or clinical guidelines.

What to do: For your most commonly authorized procedures, pull the payer's specific criteria and create a quick-reference guide for your PA staff. This guide should answer:

• What diagnoses support this procedure?
• What conservative treatments must be tried first?
• What documentation is required?
• What are the frequency or unit limits?

When your staff knows exactly what the payer is looking for, they can ensure the submission meets all criteria on the first attempt.

Impact: Requests that clearly align with published clinical criteria are approved 50-70% faster than those that require medical director review.

5. Request Peer-to-Peer Reviews Proactively

When a PA request is pending medical director review, do not wait for the payer to deny it and then appeal. Request a peer-to-peer review proactively.

What to do: If a PA request has been pending for more than the payer's stated turnaround time, or if you receive a tentative denial or request for additional information, immediately request a peer-to-peer review between the treating provider and the payer's medical director.

Impact: Peer-to-peer reviews often resolve in a single phone call what would otherwise take weeks of written back-and-forth. Many practices report that 60-80% of peer-to-peer reviews result in approval.

6. Track and Measure Your PA Metrics

You cannot improve what you do not measure. Most practices have no idea how long their PA requests actually take or what their first-pass approval rate is.

What to do: Track these key metrics:

• Average turnaround time from submission to decision, by payer
• First-pass approval rate (approved without additional information or appeal)
• Denial rate by reason code
• Average time to appeal and appeal overturn rate
• Staff hours per PA request

Review these monthly. Look for patterns: which payers are slowest? Which procedures have the highest denial rates? Where is the bottleneck in your workflow?

Impact: Practices that track PA metrics consistently reduce their turnaround time by 20-30% within 6 months simply by identifying and addressing bottlenecks.

7. Automate the Repetitive Parts

The PA workflow is full of repetitive, rule-based tasks that do not require clinical judgment:

• Checking if a CPT code requires PA for a given payer
• Looking up the payer's submission requirements and contact information
• Pre-populating PA request forms with patient and provider information
• Tracking submission status and flagging overdue requests
• Sending follow-ups on pending requests

These tasks consume the majority of staff time but add no clinical value. They are ideal candidates for automation.

What to do: Evaluate PA automation platforms that can handle requirement checking, submission, tracking, and follow-up. Even partial automation (automating the requirements check and status tracking while keeping clinical submission manual) delivers significant time savings.

Impact: Practices that implement PA automation typically see 60-85% reductions in staff time per authorization and 40-60% reductions in overall turnaround time.

Putting It All Together

The seven strategies above work together. Checking requirements at scheduling (strategy 1) gives you time to gather complete documentation (strategy 2). Submitting electronically (strategy 3) with payer-specific criteria in mind (strategy 4) maximizes your first-pass approval rate. Proactive peer-to-peer requests (strategy 5) accelerate the cases that need review. Tracking metrics (strategy 6) identifies where to focus. And automation (strategy 7) makes the entire workflow sustainable without burning out your staff.

You do not have to implement all seven at once. Start with the ones that address your biggest bottlenecks, then layer in additional improvements over time.
