Prior Authorization Automation: Reducing the $1.3 Billion Burden

Prior authorization is healthcare’s most frustrating workflow. Physician practices spend 12-14 hours weekly on prior auth, costing $2,161-$3,430 annually per physician. Industry-wide, prior authorization costs $1.3 billion annually—a 30% increase from 2022. Here’s how fax automation is finally making a dent.

The Prior Authorization Problem

By the Numbers

Metric	Value
Annual prior auth transactions	77-182 million
Still processed manually (phone/fax)	51%
Manual cost per transaction	$10.97
Electronic cost per transaction	$5.79
Physician time weekly	12-14 hours
Cost per physician annually	$2,161-$3,430
Industry administrative cost	$1.3 billion/year
Year-over-year increase	30%

The Manual Workflow

Traditional prior authorization:

1. Provider identifies need for authorization
2. Staff gathers clinical documentation
3. Form completed (often fax-based)
4. Documentation faxed to payer
5. Wait for response (phone, fax, or portal)
6. Follow up on pending requests
7. Appeal denials
8. Update EHR with outcome
9. Communicate to patient

Time: 30-60+ minutes per authorization Touches: 5-10+ per request Error Rate: High (missing info, wrong fax numbers)

Why It’s Getting Worse

Despite digital transformation elsewhere in healthcare:

• Payer portals are fragmented (different portal per payer)
• Requirements vary by payer and service
• EHR integration is limited
• Fax remains the common denominator
• Volume is increasing

Fax Automation Opportunities

Outbound Automation

Manual Process:

1. Print form from EHR
2. Gather supporting documents
3. Walk to fax machine
4. Enter fax number manually
5. Wait for transmission
6. File confirmation

Automated Process:

1. Trigger prior auth from EHR
2. System generates request with documentation
3. API sends to cloud fax
4. Confirmation logs to patient record

Time Savings: 15-25 minutes per request

Inbound Automation

Manual Process:

1. Fax arrives at machine
2. Staff retrieves from tray
3. Identify patient and request
4. Enter outcome in EHR
5. File documentation
6. Notify provider

Automated Process:

1. Fax arrives at cloud platform
2. OCR extracts patient/request identifiers
3. Auto-routes to pending request queue
4. Staff reviews and confirms
5. System updates EHR

Time Savings: 10-15 minutes per response

Tracking Automation

Manual Process:

• Spreadsheet or paper tracking
• Manual follow-up calls
• No visibility into status
• Requests fall through cracks

Automated Process:

• Dashboard shows all pending requests
• Automatic escalation for aged requests
• Status updates from all channels
• Analytics on approval rates and times

                                                        ↓
                                              Staff Review → EHR Update

Suitable for: Mid-size organizations Investment: Medium Automation level: Significant

Advanced Integration

EHR Prior Auth Module → Automation Engine → Cloud Fax API → Payer
