Patient Profile: Sarah's Primary Immunodeficiency Journey

Sarah, a 34-year-old teacher from Rochester, New York, had been battling recurrent sinus infections and pneumonia for three years. Despite multiple courses of antibiotics, she was getting sick every few months. Her primary care physician finally referred her to an immunologist after her fourth bout of pneumonia in 18 months.

The Diagnosis Process Sarah's immunologist documented a clear pattern of recurrent infections and ordered comprehensive testing:

  • Quantitative immunoglobulins showed IgG of 425 mg/dL (normal: 700-1600)
  • IgA was 45 mg/dL (normal: 70-400)
  • Poor vaccine responses to pneumococcal and tetanus vaccines
  • Normal lymphocyte counts ruled out cellular immune defects

This led to a diagnosis of Common Variable Immunodeficiency (CVID), requiring immunoglobulin replacement therapy. Sarah's doctor recommended Xembify for home subcutaneous administration, given her work schedule and preference to avoid monthly IV infusions.

Pre-Authorization Preparation

Sarah's immunologist knew that Cigna requires prior authorization for all immune globulin products, including Xembify. The preparation phase took two weeks to gather all required documentation.

Coverage Requirements at a Glance

Requirement What Cigna Needs Where to Find It
Prior Authorization Yes, mandatory for Xembify (J1558) Cigna PA Code List
Diagnosis Documentation PID with lab confirmation Clinical notes + lab results
Weight-Based Dosing Calculated per FDA guidelines Xembify prescribing information
Infection History Detailed recurrent infection record Medical records from past 2 years
Step Therapy May apply for Medicare plans Cigna Step Therapy List

Essential Documentation Gathered

Clinical Evidence Package:

  1. Immunologist's detailed letter explaining CVID diagnosis
  2. Laboratory results showing low IgG and IgA levels with reference ranges
  3. Infection history documenting 6 episodes of sinusitis/pneumonia over 18 months
  4. Vaccine response testing showing poor pneumococcal antibody titers
  5. Weight-based dosing calculation for 150 mg/kg weekly (Sarah weighs 70 kg = 10.5g weekly dose)
Tip: Counterforce Health specializes in turning insurance denials into targeted appeals by analyzing denial letters and crafting evidence-backed rebuttals aligned to each plan's specific criteria.

Initial Submission to Cigna

Sarah's clinic submitted the prior authorization through Cigna's provider portal in early March. The submission included:

Step-by-Step Submission Process

  1. Portal Access: Clinic logged into Cigna's provider portal using their NPI
  2. PA Form Completion: Used Cigna's immune globulin PA form with all required fields
  3. Documentation Upload: Attached immunologist letter, labs, and infection history
  4. Dosing Justification: Included weight-based calculation showing 10.5g weekly dose
  5. Submission Confirmation: Received tracking number CIG-2024-PA-789456
  6. Expected Timeline: Cigna's standard review is 15 business days for non-urgent requests

The clinic also submitted to Express Scripts (Cigna's specialty pharmacy partner) for fulfillment coordination.

The Denial and Why It Happened

Three weeks later, Sarah received a denial letter. The reason: "Insufficient documentation of medical necessity for subcutaneous immune globulin therapy."

Common Denial Reasons & How to Fix Them

Denial Reason What Was Missing How to Fix
"Insufficient infection history" Vague documentation Provide detailed infection timeline with dates, organisms, treatments
"Lab values not clearly documented" Missing reference ranges Include age-specific normal ranges with interpretation
"No evidence of IVIG trial/failure" Step therapy requirement Document contraindications to IVIG or prior IVIG experience
"Dosing exceeds guidelines" Calculation errors Use FDA-approved weight-based formula with clear math

In Sarah's case, the denial occurred because:

  1. The infection history lacked specific dates and microbiology results
  2. No mention of why IVIG wasn't appropriate (step therapy concern)
  3. Missing documentation of functional antibody deficiency testing

Building the Appeal

Sarah had 180 days to file an internal appeal with Cigna. Her immunologist worked with the clinic to strengthen the case.

Appeals Playbook for Cigna in New York

Level 1: Internal Appeal

  • Deadline: 180 days from denial date
  • How to Submit: Cigna provider portal or fax (verify current number with member services)
  • Required: Written appeal letter + new supporting documentation
  • Timeline: 30 days for standard review, 72 hours for expedited

Level 2: External Appeal (if needed)

  • Deadline: 4 months after final internal denial
  • Where to File: NY Department of Financial Services
  • Cost: $25 maximum (waived for financial hardship)
  • Decision: Binding on Cigna if overturned

The Strengthened Appeal Package

New Evidence Added:

  1. Detailed infection timeline with culture results and hospitalization records
  2. IVIG contraindication letter explaining Sarah's difficulty with venous access and work schedule conflicts
  3. Functional antibody testing showing poor vaccine responses despite normal-range IgM
  4. Peer-reviewed literature supporting SCIG efficacy in CVID patients
  5. Quality of life assessment documenting missed work days due to infections
From our advocates: We've seen cases where adding a simple timeline of missed work days due to infections helped demonstrate the real-world impact of untreated immunodeficiency. Payers respond to concrete evidence of how the current situation affects daily functioning.

Resolution and Approval

The internal appeal was successful. Cigna approved Xembify with the following terms:

Approval Details:

  • Duration: 6 months initial authorization
  • Dose: 10.5g weekly (150 mg/kg for 70 kg patient)
  • Site of care: Home administration approved
  • Monitoring: IgG trough levels required every 3 months
  • Renewal: Clinical response documentation needed for continuation

Sarah began treatment in May and saw immediate improvement. By her 3-month follow-up, she had experienced no new infections and her IgG trough level had improved to 650 mg/dL.

Key Success Factors

  1. Detailed clinical documentation with specific dates and outcomes
  2. Clear medical necessity rationale addressing Cigna's specific criteria
  3. Proper weight-based dosing calculations following FDA guidelines
  4. Step therapy justification explaining why IVIG wasn't appropriate
  5. Quality of life impact demonstrating functional impairment from infections
