Let’s break it down step by step.
What Is Prior Authorization?
Prior authorization (also called preauthorization, precertification, or insurance prior approval) is a requirement by health insurers that providers obtain medical insurance approval before delivering certain services, medications, or procedures.
The insurer must confirm that a treatment is medically necessary before they agree to pay for it.
It is commonly required for:
- Imaging services (MRI, CT scans)
- Surgeries and specialized procedures
- Physical therapy authorization
- Non-emergency medical authorization
- Certain brand-name medications
Without approval, providers risk insurance claims denial, resulting in financial losses or unpaid services.
Why Prior Authorization Matters in Healthcare
1. Controls Healthcare Costs
Healthcare prior authorization helps insurers manage expenses by verifying:
- Treatment necessity
- Cost-effective alternatives
- Compliance with step therapy requirements
This ensures that high-cost services are justified.
2. Ensures Medical Necessity
Insurers review documentation to confirm the treatment meets clinical guidelines. This prevents unnecessary procedures and supports evidence-based care.
3. Impacts Practice Revenue
For healthcare business owners, prior authorization directly affects:
- Cash flow
- Accounts receivable days
- Administrative workload
- Claim approval rates
Poor management can result in delayed payments and increased denials.
4. Influences Patient Experience
Approval delays may lead to:
- Postponed treatments
- Frustrated patients
- Loss of trust
- Negative reviews
Efficient medical billing and authorization improves patient satisfaction.
How the Prior Authorization Process Works (Step-by-Step)
Understanding the precertification process is key to reducing delays.
Step 1: Insurance Eligibility Verification
Before submitting an authorization request, verify:
- Active coverage
- Plan benefits
- Authorization requirements
- Referral requirements
Insurance eligibility verification prevents unnecessary denials later.
Step 2: Determine If Authorization Is Required
Check payer guidelines to confirm if the service requires:
- Prior authorization for procedures
- Non-emergency medical authorization
Many payers publish updated requirements online.
Step 3: Gather Insurance Documentation Requirements
Prepare:
- Patient clinical notes
- Diagnosis codes (ICD-10)
- Procedure codes (CPT/HCPCS)
- Treatment plan
- Proof of medical necessity
Incomplete documentation is a leading cause of delays.
Step 4: Submit Authorization Request
Requests can be submitted:
- Through payer portals
- Via clearinghouses
- By fax or phone (less common now)
This begins the formal insurance authorization process.
Step 5: Clinical Review by Insurer
The insurance company evaluates:
- Medical necessity
- Step therapy requirements
- Alternative treatments
- Cost-effectiveness
Step 6: Approval, Denial, or Request for More Information
The payer may:
- Approve (with authorization number)
- Deny (with reason)
- Request additional documentation
If denied, providers can file appeals for insurance denial.
