Set Your Goal: Understanding Cigna's Requirements

Your partnership with your physician centers on meeting Cigna's specific criteria for Oxlumo coverage. Success requires both clinical documentation and strategic presentation.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It Timeline
Genetic confirmation AGXT gene mutations documented Genetic testing report Must be on file
Elevated oxalate 24-hour urine >0.5-0.7 mmol/24h/1.73m² Recent lab results Within 6 months
Specialist prescription Nephrology/urology consultation Provider credentials Current referral
Kidney function eGFR ≥30 mL/min/1.73 m² Recent creatinine/eGFR Within 3 months
Prior authorization Completed PA form Cigna provider portal 1-3 business days

Your role: Organize documentation and advocate for thorough submission. Provider's role: Clinical assessment, letter writing, and PA submission.

Prepare for Your Provider Visit

Maximize your appointment efficiency by arriving with organized information. Your nephrologist or urologist needs a complete clinical picture to write a compelling case.

Pre-Visit Checklist

Symptom Timeline Documentation:

  • Dates of kidney stone episodes (emergency visits, procedures)
  • Progression of kidney function (creatinine trends over time)
  • Impact on daily activities (work absences, lifestyle limitations)
  • Current symptoms (pain frequency, urinary issues)

Treatment History Summary:

  • All medications tried for PH1 management
  • Pyridoxine (vitamin B6) trials: doses, duration, response
  • Conservative measures attempted (dietary restrictions, hydration)
  • Reasons for discontinuation (side effects, lack of efficacy)

Functional Impact Notes:

  • Quality of life changes since diagnosis
  • Frequency of medical appointments and procedures
  • Work or school limitations
  • Family planning considerations (genetic counseling needs)
Tip: Create a one-page summary with dates, medications, and outcomes. This helps your provider quickly grasp your treatment journey and strengthens the medical necessity argument.

Build Your Evidence Kit

Strong documentation accelerates approval and reduces back-and-forth requests from Cigna. Gather these materials before your appointment:

Essential Documents

Genetic Testing Results:

  • Complete AGXT gene sequencing report
  • Genetic counselor's interpretation (if available)
  • Family history documentation (affected relatives)

Laboratory Evidence:

  • Most recent 24-hour urine oxalate collection
  • Plasma oxalate levels (if measured)
  • Kidney function tests (creatinine, eGFR, BUN)
  • Urinalysis showing crystals or stones

Imaging and Procedures:

  • Kidney ultrasounds or CT scans showing nephrocalcinosis
  • Stone analysis reports (calcium oxalate confirmation)
  • Surgical reports from stone removal procedures

Published Guidelines: Your provider will reference these, but familiarizing yourself helps with discussions:

Medical Necessity Letter Structure

Work with your provider to ensure the letter includes all required elements. Counterforce Health specializes in turning insurance denials into targeted appeals by analyzing payer policies and crafting evidence-backed rebuttals that align with each plan's specific requirements.

Key Components for Your Provider

Diagnosis Section:

  • ICD-10 code E72.53 (Primary hyperoxaluria)
  • Specific AGXT mutations identified
  • Date of genetic confirmation
  • Clinical presentation at diagnosis

Clinical Rationale:

  • Current oxalate levels with reference ranges
  • Kidney function status and trajectory
  • Stone burden and recurrence pattern
  • Risk of progression without treatment

Treatment History:

  • Prior therapies attempted (pyridoxine response)
  • Contraindications to alternatives
  • Why conservative management is insufficient
  • Urgency of intervention

Monitoring Plan:

  • Follow-up schedule for oxalate levels
  • Kidney function monitoring protocol
  • Expected treatment response timeline
  • Long-term management strategy

Template Language for Providers

"This patient has genetically confirmed PH1 with biallelic pathogenic AGXT mutations [specify]. Current 24-hour urinary oxalate excretion is [value] mmol/24h/1.73 m², significantly elevated above normal limits. Despite [prior treatments], oxalate levels remain elevated with ongoing risk of irreversible kidney damage. Oxlumo represents the only FDA-approved therapy specifically targeting hepatic oxalate production in PH1."

Support Your Doctor Through Peer-to-Peer

If Cigna requests a peer-to-peer (P2P) review, your preparation directly supports your provider's success in these medical director conversations.

P2P Preparation Support

Availability Windows:

  • Provide your provider's office with flexible scheduling options
  • Confirm your availability for follow-up questions during the review period
  • Offer to gather additional documentation quickly if requested

Concise Case Summary: Create a one-page "P2P cheat sheet" for your provider:

  • Patient age, diagnosis date, genetic mutations
  • Current oxalate levels and kidney function
  • Prior treatment failures with specific details
  • Clinical urgency factors (stone recurrence, function decline)

Key Talking Points:

  • Emphasize PH1 as a progressive, life-threatening condition
  • Highlight lack of alternative therapies with similar mechanism
  • Reference FDA approval and clinical trial data
  • Note that delays risk irreversible kidney damage

After Your Visit: Documentation Strategy

Proper documentation after your appointment ensures continuity and appeal readiness.

What to Save

Provider Communications:

  • Copy of medical necessity letter before submission
  • PA submission confirmation number
  • Provider portal screenshots showing submission status
  • Any follow-up communications from Cigna

Clinical Documentation:

  • Updated problem list including PH1 diagnosis
  • Treatment plan notes from your visit
  • Prescription details (NDC codes, dosing, quantity)
  • Referral documentation if seeing new specialists

Portal Messaging Best Practices

When communicating with your provider through patient portals:

  • Subject lines: Be specific ("Oxlumo PA status update needed")
  • Concise requests: "Please confirm Cigna received our PA submission on [date]"
  • Attach relevant documents: New lab results, Cigna correspondence
  • Response timeline: Allow 2-3 business days for non-urgent messages

Respectful Persistence: Follow-Up Protocol

Effective follow-up maintains momentum without overwhelming your healthcare team.

Follow-Up Cadence

Week 1: Confirm PA submission and tracking number Week 2: Check status if no response from Cigna Week 3: Escalate if approaching standard review deadline Beyond 3 weeks: Prepare for appeal process

Escalation Strategy

Provider Office Level:

  1. Start with nurse or medical assistant
  2. Request provider callback if needed
  3. Schedule brief follow-up appointment for complex issues

Insurance Level:

  1. Call Cigna member services for status updates
  2. Document all phone interactions (date, representative name, reference numbers)
  3. Request written confirmation of any verbal approvals

When to Escalate to Illinois Regulators:

  • PA decision exceeds standard timeframes without explanation
  • Cigna fails to follow their own published policies
  • Provider receives conflicting information from different representatives

Contact the Illinois Department of Insurance at 877-527-9431 for assistance with coverage disputes.

Common Denial Reasons & Solutions

Understanding typical denial patterns helps you and your provider prepare stronger initial submissions and appeals.

Denial Reason: Insufficient Genetic Documentation

Solution: Ensure genetic testing report clearly states:

  • Biallelic pathogenic AGXT mutations
  • Laboratory performing testing (CLIA-certified)
  • Clinical interpretation confirming PH1 diagnosis
  • Genetic counselor review if available

Denial Reason: Oxalate Levels Not Elevated Enough

Solution: Provide comprehensive oxalate documentation:

  • 24-hour urine collection with proper technique verification
  • Body surface area correction for pediatric patients
  • Multiple measurements if initial values borderline
  • Plasma oxalate if urine collection unreliable

Denial Reason: Non-Specialist Prescriber

Solution: Ensure prescription comes from:

  • Board-certified nephrologist or urologist
  • Provider with documented PH1 experience
  • Academic medical center if community specialist unavailable
  • Consultation notes from appropriate specialist

Denial Reason: Inadequate Prior Treatment Documentation

Solution: Document all conservative measures:

  • Pyridoxine trials with specific doses and duration
  • Dietary oxalate restriction attempts
  • Increased fluid intake protocols
  • Reasons for treatment failure or intolerance
