Prior Authorization in Healthcare: Complete Process Guide to Reduce Treatment Delays
Prior authorization has become the gatekeeper of modern healthcare. Insurance companies require approval before many treatments, procedures, and medications are provided. Yet the process remains one of the biggest frustrations for patients and providers alike, causing delays that can impact patient outcomes and clinical urgency.
This comprehensive guide breaks down the prior authorization process step-by-step, explains why it exists, identifies procedures that require authorization, and provides proven strategies to reduce approval delays. Whether you're a healthcare provider, billing professional, or patient advocate, understanding this process is critical for ensuring timely care.
What is Prior Authorization and Why Does It Exist?
Definition and Purpose
Prior authorization (also called prior approval, pre-authorization, or pre-approval) is a requirement by insurance companies to receive approval BEFORE providing certain healthcare services, procedures, medications, or treatments.
The insurance company reviews the request and either:
- Approves the service (authorization granted)
- Conditionally approves with limitations
- Denies the service (not covered or not medically necessary)
- Requests more information before deciding
Why Insurance Companies Require Prior Authorization
Insurance companies use prior authorization to:
1. Manage Costs
- Prevent unnecessary or overly expensive procedures
- Encourage use of less expensive alternatives
- Control utilization of high-cost services
- Negotiate volume discounts
2. Ensure Medical Necessity
- Verify the procedure/medication is appropriate for the diagnosis
- Prevent procedures not supported by clinical guidelines
- Reduce fraud and abuse
- Align with evidence-based medicine
3. Prevent Inappropriate Care
- Reduce surgical procedures that don't meet clinical criteria
- Prevent overtreatment
- Encourage conservative approaches first (less costly)
- Improve patient outcomes through guided care
4. Manage Network Providers
- Control where patients access care
- Ensure services are from contracted providers
- Manage facility utilization
- Track quality metrics for providers
Why Providers Complain About Prior Authorization
Despite the stated purpose, prior authorization creates significant operational challenges:
Administrative Burden:
- Average 20-30 minutes per authorization request
- Requires clinical staff time away from patient care
- Multiple payers with different requirements
- Manual processes (phone, fax, web portals)
Care Delays:
- Average approval time: 3-5 business days
- Urgent cases may take 24 hours
- Emergency care can't wait for authorization
- Some treatments lose efficacy if delayed
Denial Rates:
- Overall prior auth denial rate: 5-10%
- Cardiology: 10-15% denial rate
- Mental health: 15-20% denial rate
- Specialty procedures: 12-18% denial rate
Patient Impact:
- Delayed care causes clinical deterioration
- Patients defer needed treatment due to uncertainty
- Increased anxiety about cost/coverage
- Treatment outcomes affected by delays
The Controversy Around Prior Authorization
Medical organizations increasingly criticize prior authorization:
American Medical Association (AMA) Position:
- Prior auth creates "unacceptable administrative burden"
- Contributes to healthcare provider burnout
- Can delay necessary care
- Increases healthcare costs (admin overhead)
Proposed Reforms:
- Streamlined electronic prior authorization (ePA)
- Reduced documentation requirements
- Faster turnaround times (24-48 hours)
- Transparent coverage criteria
- Limited prior auth requirements
Understanding the Prior Authorization Landscape
Who Requires Prior Authorization?
Insurance Types Requiring Prior Auth:
1. Managed Care Plans (HMOs, PPOs)
- Most likely to require prior authorization
- Network management requirement
- Multiple prior auth requirements common
2. Medicare Advantage Plans
- Require prior auth for many services
- Vary by specific plan
- More restrictive than Original Medicare
3. Original Medicare (Fee-for-Service)
- Generally fewer prior auth requirements
- Limited National Coverage Determinations
- Local Coverage Determinations may require auth
4. Medicaid Plans
- Highly variable by state
- Often require prior auth for expensive procedures
- Pharmacy requirements common
5. Commercial Insurance Plans
- Most restrictive for prior authorization
- Frequent requirements across many services
- Highest denial rates
Important: Not all services require prior authorization. Common non-authorized services include:
- Office visits (usually)
- Preventive care (usually)
- Emergency care (retroactive auth only)
- Routine lab tests (usually)
- Basic imaging (sometimes auth required)
The Prior Authorization Process: Step-by-Step
Understanding the complete process helps you navigate it efficiently.
STEP 1: Determine if Prior Authorization is Required
How to Check:
Method 1: Insurance Benefit Documents
- Review plan's Summary of Benefits and Coverage (SBC)
- Check plan website's authorization requirements
- Call insurance customer service line
- Note: Not always 100% accurate; may have updates
Method 2: Provider Resources
- Check your practice's authorization matrix by payer
- Reference your billing software's prior auth module
- Ask your insurance liaison/representative
- Review recent authorization patterns with same payer
Method 3: Direct Payer Inquiry
- Call insurance authorization department
- Have patient's ID number and DOB ready
- Confirm specific procedure/medication requiring auth
- Document confirmation in patient record
- Get authorization requirements
Red Flag Procedures (Often Require Auth):
- Advanced imaging (MRI, CT, PET scans)
- Surgical procedures (especially orthopedic, cardiac)
- Mental health services (especially intensive)
- Specialty medications (especially biologics)
- Durable medical equipment (DME)
- Home health and rehabilitation services
- Infusion therapies
Pro Tip: Many practices check authorization requirements at the time of scheduling. This prevents surprise delays later.
STEP 2: Gather Required Documentation
Essential Information to Have Ready:
Patient Information:
- Full legal name
- Date of birth
- Insurance ID number (front of card)
- Group number (back of card)
- Effective dates of coverage
- Any secondary insurance
Provider Information:
- National Provider ID (NPI)
- Practice contact information
- Treating physician name and credentials
- Specialist performing procedure (if different from referring provider)
Clinical Information:
- Diagnosis code (ICD-10)
- Procedure code (CPT) or medication name/NDC
- Clinical indication (why procedure is medically necessary)
- Relevant clinical findings (test results, measurements, etc.)
- Medications already tried (for medication auth)
- Treatment history relevant to request
- Expected date of service
Documentation Requirements by Payer:
Most payers require some combination of:
- Patient demographics and insurance verification
- Provider and facility information
- Diagnosis and procedure codes
- Clinical narrative explaining medical necessity
- Relevant lab results or imaging
- Previous treatment attempts (especially for medications)
- Clinical guidelines supporting procedure
- Physician's statement regarding urgency
STEP 3: Submit the Prior Authorization Request
Submission Methods (In Order of Speed):
1. Electronic Prior Authorization (ePA) - FASTEST
- Integrated into practice management system
- Automated response in 5-60 minutes for many payers
- Highest adoption with major payers
- Most efficient method
2. Online Payer Portals - MODERATE SPEED
- Direct submission through insurance company website
- 24-48 hour turnaround typical
- Can track status online
- May require account setup
3. Phone/Telephone - MODERATE TO SLOW
- Call insurance authorization department
- Live person can ask clarifying questions
- Verbal approval given, followed by written confirmation
- 30 minutes to several hours for approval
- Can be inefficient if transferred between departments
4. Fax - SLOW
- Traditional method still used by many payers
- Cover sheet with specific patient/procedure info
- 2-5 business days typical turnaround
- Difficult to track status
- May require follow-up call
5. Mail - SLOWEST (Not Recommended)
- Rarely used due to delays
- Can take 5-10 business days
- No tracking ability
- Only used when other methods unavailable
Best Practice: Use electronic submission (ePA or online portal) for non-urgent authorizations. Phone for urgent cases.
STEP 4: Track the Authorization Request
Tracking Process:
Submission Date: [Date]
Payer: [Insurance Company]
Authorization Reference Number: [#]
Expected Decision Date: [Date + 3-5 business days]
Status Check Timeline:
- Day 1: Confirm receipt with payer
- Day 2-3: Check status via portal or call
- Day 4-5: If no decision, escalate to supervisor
- Day 6+: If still pending, file complaint with state insurance commissioner
What You're Looking For:
- Pending: Request under review
- More Information Needed: Submit additional documentation
- Approved: Authorization granted (get authorization number!)
- Approved with Conditions: Coverage limited (review conditions)
- Denied: Not approved (note reason for appeal)
Critical: Write down the authorization number. You'll need this to submit claims.
STEP 5: Receive and Document the Authorization
What You'll Receive:
Authorization Letter Will Include:
- Patient name and ID number
- Authorization number (unique identifier)
- Procedure/service authorized
- Dates of authorization (valid dates)

3. Clinical documentation auto-populated
4. Submitted to payer via ePA system
5. Payer's system validates information
6. If complete, automated decision or medical review
7. Response sent back electronically
8. Authorization number issued
9. All documented in patient record
Timeline Comparison:
| Method | Submission | Processing | Response | Total Time |
|---|---|---|---|---|
| ePA | Instant | 5-60 min | Real-time | 5 min-1 hour |
| Online Portal | 5-10 min | 24 hours | 24-48 hours | |

Frequently Asked Questions About Prior Authorization
Q: What's the difference between prior authorization and a referral?
A: Referral is when your primary care doctor sends you to a specialist. It's often required for HMO plans to receive specialist care.
Prior authorization is when the insurance company approves a specific service/procedure before it's provided.
You may need both: a referral to see the specialist AND prior authorization for the specialist's proposed procedure.
Q: Does prior authorization guarantee payment?
A: No. Prior authorization means:
- The service is medically necessary
- The service is covered by the plan
- The procedure meets authorization criteria
But payment is NOT guaranteed if:
- Patient's coverage lapses between authorization and service
- Patient's benefits change
- Coding on the claim differs from authorization
- Other policy violations occur
Always verify coverage immediately before the service.
Q: How long is a prior authorization valid?
A: Validity varies by payer and service:
- Standard: 30-60 days from authorization date
- Extended care: 90-180 days for ongoing services
- Some authorizations: 1 year for ongoing conditions
Always check the authorization letter for expiration date. Don't perform services after the authorization expires without requesting renewal.
Q: What if I perform a service without prior authorization?
A: Consequences vary:
- Non-required service: No problem, bill normally
- Required but not obtained: Claim will be denied
- You may be responsible for bill (check contract)
- Patient may owe balance (review balance billing rules)
- Resubmit with retroactive authorization request (40% success rate)
- Emergencies: Perform care, submit for retroactive authorization
Prevention: Always verify authorization status before scheduling.
Q: Can I appeal a denied prior authorization?
A: Yes, absolutely. Most denials are appealable.
Appeal Success Rates:
- Overall: 30-50% of appeals successful
- With clinical evidence: 50-70% success
- With physician phone support: 60-75% success
Timeline: Submit appeal within 30-60 days of denial. Don't wait.
Q: How much should I tell a patient about prior authorization?
A: Patient communication should include:
- Explain what prior authorization is (briefly)
- Say authorization is needed for [service]
- Provide timeline: "Usually takes 2-3 days"
- Explain they may be contacted by insurance
- Clarify their cost responsibility
- Provide authorization number once received
Don't: Make them feel like there's a problem or that approval is uncertain (unless it is).
Q: What's the fastest way to get prior authorization?
A: In order of speed:
- ePA (Electronic): 5 minutes to 2 hours (if available)
- Phone call: 1-4 hours (expedited)
- Online portal: 4-12 hours (for urgent)
- Phone (standard): Next business day
- Online portal: 24-48 hours
- Fax: 2-5 business days
Use ePA when available. Call for urgent cases. Avoid fax.
Q: Can I use the same prior authorization for multiple visits?
A: Sometimes. It depends on the authorization:
Single-date authorizations: Cannot be reused (one-time only)
Multi-visit authorizations: Can be used for all authorized visits within date range
- Example: "PT authorization for up to 12 visits between 10/27/24 - 12/27/24"
Always check the authorization letter. If in doubt, request renewal for continued services.
Q: How do I know if ePA is available with my payer?
A: Ways to check:
- Ask your billing software vendor (do they support ePA?)
- Call the insurance company's provider line
- Check the payer's website for ePA information
- Ask other practices in your specialty
- Contact your payer's account representative
ePA availability is growing rapidly. Ask about it even if not currently offered.
Q: What's the most common reason for prior authorization denial?
A: #1: Lack of medical necessity (35% of denials)
- Procedure doesn't meet clinical criteria
- Diagnosis doesn't support procedure
- Conservative treatment not attempted first
- Doesn't meet established guidelines
Prevention: Ensure documentation supports medical necessity clearly.
Q: Should I bill the patient while waiting for prior authorization?
A: General rules:
Don't bill until:
- Authorization received AND
- Service already delivered (in some cases)
Bill after service if:
- Authorization received before service
- Verbal authorization confirmed (note confirmation)
- Emergency care (bill, seek retroactive auth)
Check your patient consent form regarding authorization status before service delivery.
Q: What if a patient's coverage lapses after prior authorization is issued?
A: Call the insurance company immediately to determine:
- Whether authorization remains valid despite lapsed coverage
- If patient lost coverage, usually authorization becomes void
- Whether patient can reinstate coverage
- What happens to any services already authorized
Don't assume authorization remains valid. Verify coverage immediately before service.
