Prior auth forms — extracted and structured. No more re-keying faxes.

Lido extracts patient demographics, procedure codes, diagnosis codes, and referring provider details from faxed and scanned prior authorization forms, and produces submit-ready structured data for your EHR or payer portal. Your clinical staff stops re-keying faxes and starts reviewing decisions.

  • Reads faxed and scanned prior auths. Prior auth forms arrive by fax, scanned PDF, or portal download. Lido handles all of these in the same pipeline, low-resolution fax quality, handwritten annotations, and multi-page attachments all processed without special handling.
  • Extracts CPT, ICD-10, and modifier codes. Procedure codes, diagnosis codes, and modifiers are extracted and validated against standard code formats. Malformed or incomplete codes are flagged before the request is submitted.
  • HIPAA-compliant processing. Patient data is processed and deleted within 24 hours. Lido does not store PHI — your data leaves no residual footprint after extraction is complete.

How prior authorization processing works in Lido

Prior authorizations are time-sensitive. A delayed auth means a delayed procedure, and a frustrated patient. The bottleneck is almost always manual: someone has to read the fax, re-key the codes, and submit to the payer portal by hand. Lido eliminates that step.

1. Prior auth forms arrive by fax or as scanned PDFs

Faxed prior authorization requests and clinical justification attachments arrive as TIFF or PDF files through your fax-to-email service or document management system. Lido picks them up from a watched folder or inbox and queues each form for extraction automatically. Multi-page faxes, auth request plus clinical notes, are processed as a single document.

2. Patient and clinical fields are extracted

From each prior auth form, Lido extracts patient name, date of birth, member ID, insurance plan, group number, attending physician NPI, referring provider NPI, facility name, requested procedure (CPT codes), primary and secondary diagnosis codes (ICD-10), requested service dates, and clinical justification notes. Handwritten fields, common in physician sign-off sections, are read via handwriting OCR.

3. Code formats are validated before submission

Extracted CPT codes are validated against the 5-digit format; ICD-10 codes are checked against standard format (letter + 2 digits + decimal + up to 4 digits). Codes that do not match expected formats are flagged with the extracted value and the expected pattern, so your billing team can correct the form before it reaches the payer portal, not after.

4. Urgency flags are detected from form content

Prior auth forms for urgent or emergent procedures often include urgency indicators, a checkbox, a handwritten note, or a clinical urgency code. Lido detects these markers and routes urgent requests to the front of the queue, ensuring time-sensitive authorizations are not processed in batch order.

5. Structured data is output for EHR entry or payer portal submission

The extracted data is output as a structured spreadsheet or JSON payload mapped to your EHR fields or payer portal submission format. Each field is pre-filled. Your authorization coordinator reviews flagged items, approves clean records, and submits, no re-keying required.

Prior auth document types Lido handles

Payer-specific prior authorization request forms

Each major payer. UnitedHealthcare, Cigna, Aetna, Humana, BCBS plans, has its own prior auth form. Lido reads any payer form without per-payer templates.

CMS AMA standard prior auth forms

Standardized prior authorization forms used by Medicare Advantage plans and AMA-aligned payers. Structured fields are extracted consistently across all CMS-format variants.

Clinical justification attachments

Physician notes, diagnostic imaging reports, and lab results attached to the prior auth request. Lido extracts key clinical indicators referenced in the justification, such as diagnosis, treatment history, and clinical criteria met.

Faxed multi-page prior auth packets

Multi-page fax packets that include the auth request form, clinical notes, and supporting records. Lido splits the packet by document type and extracts each section with the appropriate schema.

Referral authorization forms

Referral authorization requests from PCPs to specialists. Extract referring provider, referred-to specialist, reason for referral, and authorization period.

Retro-authorization request forms

Retrospective authorization requests filed after an urgent procedure. Same extraction schema as prospective auths, with the procedure date already in the past.

Why manual prior auth processing creates clinical and administrative delays

The fax-to-keyboard bottleneck

A prior auth fax arrives at 8:47 AM for a patient scheduled for Thursday. The authorization coordinator downloads the fax, reads the patient name and member ID, opens the payer portal, types in the member ID, enters the CPT code, enters the ICD-10 code, attaches the clinical notes, and submits. If any field is mistyped, a transposed digit in the member ID, a CPT code entered without a modifier, the request is rejected and the process starts over. Meanwhile, the patient is still waiting for Thursday's procedure to be confirmed.

Lido extracts and validates the prior auth fields in seconds

Lido reads the fax, extracts every required field, validates code formats, and flags anything that will cause a payer rejection before the request is submitted. Your authorization coordinator reviews a pre-filled record, corrects any flagged items, and submits in under two minutes per auth. Urgent cases are surfaced automatically so Thursday's patient is handled before the batch backlog.

Common use cases

Multi-Provider Medical Practice

Process high-volume prior auth queues across specialties

A 12-physician orthopedic practice submits 80 prior auths per week across surgical procedures, MRIs, and physical therapy. Faxed prior auth forms are extracted automatically, CPT and ICD-10 codes validated, and the authorization queue cleared same-day instead of accumulating into a 2-day backlog.

Hospital System

Centralize prior auth processing across departments

A 300-bed hospital handles prior auth requests from cardiology, oncology, orthopedics, and radiology in a central authorization team. Lido routes extracted prior auths to the correct specialist coordinator based on the procedure code, eliminating the manual triage step that caused 4-hour processing delays.

Specialty Clinic

Manage prior auth turnaround for time-sensitive procedures

An oncology clinic submits prior auths for chemotherapy regimens requiring 48-hour turnaround. Lido detects urgency flags on incoming faxes and routes time-sensitive auths to the front of the queue, ensuring treatment schedules are not delayed by authorization backlogs.

Medical Billing Company

Handle prior auth processing for multiple practice clients

A billing company managing authorization workflows for 15 physician practices receives prior auth faxes from multiple fax numbers into a centralized inbox. Lido routes each extracted prior auth to the correct practice client and submission queue based on the NPI extracted from the form.
