Why Is Fax Required for Prior Authorization?
Prior authorization is a requirement from insurance companies before certain medications, procedures, or referrals are approved. Fax remains the dominant method for submitting these requests. Here is why:
Insurance Requirement
Most health insurers and pharmacy benefit managers (PBMs) require prior auth forms to be submitted by fax. Their intake systems are built around fax-based workflows.
Time-Sensitive
Prior authorization requests are often urgent — a patient may be waiting for medication or a scheduled procedure. Fax delivers immediately with confirmation.
Standard Forms
Insurers use standardized prior auth forms that require physician signatures. Fax transmits these signed forms directly without format conversion issues.
Audit Trail
Fax delivery confirmation provides a timestamped record that the prior auth request was submitted, which is important for expedited and urgent appeals.

FaxItOnce handles all common prior auth documents. Upload your PDF and send to any fax number for a flat $2.75.
Medication Prior Auth
Submit prior authorization requests for specialty medications, non-formulary drugs, and controlled substances to insurance companies or PBMs.
Procedure Pre-Auth
Fax pre-authorization forms for surgical procedures, inpatient admissions, and outpatient treatments that require insurer approval before scheduling.
Specialist Referral Auth
Send referral authorization requests when a primary care provider needs insurer approval before referring a patient to a specialist.
Imaging/Diagnostic Auth
Submit prior auth requests for MRI, CT scan, PET scan, and other diagnostic imaging procedures that require insurance pre-approval.
DME Authorization
Fax durable medical equipment authorization forms for wheelchairs, CPAP machines, prosthetics, and other prescribed equipment.
Appeals for Denied Auth
