Set Your Goal: What Approval Requires

Getting Xospata (gilteritinib) covered by Blue Cross Blue Shield in Pennsylvania starts with understanding exactly what your plan requires. This oral FLT3 inhibitor costs approximately $29,000 per month and requires prior authorization from all major Blue Cross plans in the state.

Core Requirements for Approval

Your Blue Cross Blue Shield plan will typically require:

Requirement What It Means Documentation Needed
FLT3 Mutation Confirmed FLT3-ITD or TKD mutation Lab report from FDA-approved test
Disease Status Relapsed or refractory AML Bone marrow biopsy, prior treatment records
Specialist Care Hematologist/oncologist prescriber Provider NPI and specialty designation
Prior Therapy Evidence of previous treatment failure Treatment timeline with dates and outcomes

Pennsylvania Blue Cross Landscape

Pennsylvania has several Blue Cross entities, including Highmark Blue Shield, Independence Blue Cross, and Capital Blue Cross. Each has slightly different prior authorization forms and submission processes, but all follow similar medical necessity criteria for specialty oncology drugs.

Note: Pennsylvania's Insurance Department reports that roughly 14% of health insurance claims statewide are initially denied, but the state's new Independent External Review program has overturned about 50% of appealed denials since launching in 2024.

Visit Preparation: Building Your Case

Before your appointment, create a comprehensive timeline that your oncologist can use to build a strong prior authorization request.

Symptom and Treatment Timeline

Document your AML journey chronologically:

Initial Diagnosis:

  • Date of first symptoms and diagnosis
  • Bone marrow biopsy results and cytogenetics
  • FLT3 testing results (include lab name and test method)

Prior Treatments:

  • Each therapy regimen with start/stop dates
  • Best response achieved (complete remission, partial response, etc.)
  • Reason for stopping (progression, toxicity, lack of response)
  • Any hospitalizations or complications

Functional Impact Notes

Track how AML affects your daily life:

  • Fatigue levels and activity limitations
  • Transfusion requirements and frequency
  • Work or school disruptions
  • Quality of life changes

This information helps your doctor demonstrate medical necessity and urgency in the prior authorization request.

Evidence Kit: Essential Documentation

Gather these critical documents before your appointment:

Laboratory and Imaging

  • FLT3 mutation test results (most important document)
  • Recent bone marrow biopsy reports
  • Complete blood counts showing cytopenias
  • Flow cytometry results
  • Any molecular monitoring results

Treatment Records

  • Discharge summaries from previous hospitalizations
  • Chemotherapy administration records
  • Transplant consultation notes (if applicable)
  • Previous medication trial documentation

Insurance Information

  • Current Blue Cross Blue Shield member ID card
  • Summary of benefits and coverage (SBC)
  • Any previous denial letters
  • Explanation of benefits (EOB) statements
Tip: Request copies of all lab reports and treatment summaries at least one week before your appointment. Many patients underestimate how long it takes to gather complete records.

Medical Necessity Letter Structure

Your hematologist/oncologist will need to write a comprehensive letter of medical necessity. Here's what should be included:

Essential Components

Patient Demographics and Diagnosis:

  • Full name, date of birth, member ID
  • ICD-10 code for AML (typically C92.02)
  • Clear statement: "Adult with relapsed/refractory FLT3-mutated AML"

FLT3 Testing Documentation:

  • Test date, laboratory name, and methodology
  • Specific mutation type (FLT3-ITD, FLT3-TKD, or both)
  • Allelic ratio if available

Prior Therapy History:

  • Chronological list of all previous treatments
  • Response duration and reason for discontinuation
  • Explicit statement of "relapsed" or "refractory" status

Clinical Rationale:

  • Why Xospata is medically necessary now
  • Why alternative treatments are inappropriate
  • Treatment goals (remission, bridge to transplant, palliation)

Guideline Support:

  • Reference to NCCN Guidelines for AML
  • FDA labeling for Xospata indication
  • Published clinical trial data supporting use

Sample Key Phrases

Your doctor should include language like:

  • "Patient meets FDA-approved indication for gilteritinib"
  • "FLT3 mutation confirmed by [specific test name] on [date]"
  • "Failed prior therapies including [list specific regimens]"
  • "No contraindications to FLT3 inhibitor therapy"
  • "Will monitor for QT prolongation and differentiation syndrome per label"

Peer-to-Peer Review Support

If your initial prior authorization is denied, Blue Cross Blue Shield may offer a peer-to-peer review where your oncologist speaks directly with a medical director.

How You Can Help

Scheduling Flexibility:

  • Provide your doctor's office with multiple time windows when they're available for calls
  • Understand that these calls often happen with short notice

Case Summary Preparation: Help your clinical team prepare a one-page summary including:

  • Your age, performance status, and key comorbidities
  • FLT3 mutation details and testing date
  • Prior treatments with specific dates and outcomes
  • Current disease status and urgency factors
  • Clear request for Xospata approval

Key Arguments for Your Doctor

Successful peer-to-peer reviews typically emphasize:

  • Guideline concordance with NCCN recommendations
  • Lack of effective alternatives for FLT3-mutated disease
  • Time-sensitive nature of relapsed/refractory AML
  • Plan to monitor safety parameters per FDA labeling

After Your Visit: Next Steps

Documentation to Save

Request copies of:

  • The completed prior authorization form
  • Medical necessity letter
  • All supporting clinical documents
  • Submission confirmation (fax receipt or portal confirmation)

Portal Communication

Use your Blue Cross member portal or your doctor's patient portal to:

  • Track prior authorization status
  • Request updates if processing exceeds typical timeframes
  • Upload additional documents if requested

Timeline Expectations

Most Blue Cross plans in Pennsylvania process prior authorizations within:

  • Standard requests: 15 business days
  • Expedited requests: 72 hours (for urgent medical situations)
  • Appeals: 30 days for internal appeals

Appeals Playbook for Pennsylvania

Pennsylvania strengthened its health insurance appeals system in 2024 with a new state-run external review program.

Internal Appeal Process

Step 1: File with Blue Cross

  • Submit within 180 days of denial
  • Use plan-specific appeal form
  • Include additional clinical documentation
  • Request expedited review if medically urgent

Step 2: Await Decision

  • Standard appeals: 30 days
  • Expedited appeals: 72 hours
  • Decision is called "Final Adverse Benefit Determination"

Pennsylvania Independent External Review

If your internal appeal is denied, you can request an independent external review through the Pennsylvania Insurance Department.

Eligibility:

  • Must have completed internal appeal process
  • Denial must be based on medical necessity, not benefit exclusion
  • Must file within 4 months of final internal denial

Process:

  • Submit request online at pa.gov
  • Independent Review Organization (IRO) assigned within 1 business day
  • You have 15 days to submit additional evidence
  • Decision within 45 days (72 hours for expedited)

Success Rates: Pennsylvania reports that approximately 50% of external reviews result in overturning the insurer's denial.

Common Denial Reasons & Solutions

Denial Reason How to Fix It Required Documentation
Missing FLT3 test Submit complete lab report CLIA-certified lab report with mutation details
Insufficient prior therapy Document treatment timeline Chemotherapy records, response assessments
Non-specialist prescriber Transfer care or get consultation Hematology/oncology referral
"Experimental" designation Emphasize FDA approval FDA labeling, NCCN guidelines
Step therapy requirement Document contraindications Medical records showing why alternatives failed
From our advocates: We've seen cases where patients were initially denied because their FLT3 test was done at diagnosis but not re-confirmed at relapse. If your original test is more than 6 months old, ask your doctor about repeat testing to strengthen your case.

FAQ

How long does Blue Cross Blue Shield prior authorization take in Pennsylvania? Standard prior authorizations take up to 15 business days. Expedited reviews for urgent medical situations are completed within 72 hours.

What if Xospata is non-formulary on my plan? You can request a formulary exception by demonstrating medical necessity and failure of preferred alternatives. The process is similar to prior authorization but may require additional documentation.

Can I request an expedited appeal if my AML is progressing? Yes. If your doctor certifies that delay poses a serious threat to your health, you can request expedited internal and external reviews with much shorter timelines.

Does step therapy apply if I've tried treatments outside Pennsylvania? Treatment history from other states counts toward step therapy requirements. Provide complete documentation of all prior therapies regardless of where they were administered.

What happens if my external review is approved? Blue Cross must immediately provide coverage for Xospata, including retroactive coverage if you paid out-of-pocket during the appeal process.

Can I get help with the appeals process? Yes. Contact the Pennsylvania Insurance Department Consumer Services at the phone number listed on their website, or reach out to patient advocacy organizations for free assistance.
