Renewal Triggers: When to Start Early

Your Xembify renewal clock starts ticking 60-90 days before your current authorization expires. Don't wait for the expiration notice—most Aetna CVS Health plans in Florida require renewal submissions at least 2 weeks prior to avoid treatment interruptions.

Start your renewal process if:

  • Your current PA expires within 60 days
  • You've had breakthrough infections or worsening symptoms
  • Your IgG levels have changed significantly
  • Your dosing has been adjusted
  • You've switched from another immunoglobulin product
Tip: Set a calendar reminder for 75 days before expiration. This gives you time to gather documentation and handle any complications.

Early renewal warning signs:

  • CVS Specialty mentions upcoming expiration during delivery calls
  • Your provider receives renewal reminder notices
  • You notice "Days Supply Remaining" dropping below 30 on your prescription label

If Coverage Lapses: Bridge Options & Emergency Steps

Immediate Actions for Coverage Gaps

Contact priorities (within 24 hours):

  1. Your prescribing physician - Discuss bridge therapy options
  2. CVS Specialty Pharmacy (1-800-237-2767) - Request emergency supply if available
  3. Aetna Member Services - Confirm renewal status and expedite if possible

Bridge Therapy Considerations

Clinical options to discuss with your physician:

  • Temporary IVIG if you have established IV access and infusion site
  • Emergency SCIG supply from local specialty pharmacy
  • Dose interval adjustment if clinically appropriate for short periods
  • Prophylactic antibiotics for high-risk patients during gaps
Note: Bridge therapy decisions are medical determinations made by your healthcare team, not your insurance company.

Emergency Authorization Process

For urgent situations, your provider can request expedited prior authorization:

  • Submit clinical urgency documentation
  • Include statement of medical necessity for immediate treatment
  • Expect decision within 72 hours for commercial plans
  • Follow up daily until resolved

When Counterforce Health works with patients facing coverage gaps, we've seen that having a detailed bridge plan ready—developed with your medical team—can prevent dangerous interruptions in immunoglobulin therapy while appeals are processed.

Annual Changes: What to Re-Verify Each Year

Level 1: Standard Internal Appeal

  • Deadline: 180 days from denial

External Review Process

If internal appeals are unsuccessful, Florida residents can request independent external review through the state's contracted review organizations.

Timeline and process:

  • File within: 4 months of final internal denial (120 days for Medicaid)
  • Decision timeline: 30-45 days (expedited available for urgent cases)
  • Cost: No charge to patient
  • Contact: Florida Department of Financial Services (1-877-693-5236)

Required documentation:

  • Copy of final denial letter
  • All medical records supporting medical necessity

  • Statement of clinical urgency (if requesting expedited review)
From our advocates: We've seen successful external reviews when families include a comprehensive timeline showing their loved one's infection history before and after starting Xembify, along with documentation of failed alternative treatments. The key is painting a clear picture of medical necessity that an independent physician reviewer can easily follow.

FAQ: Common Renewal Questions

How long does Aetna CVS Health prior authorization renewal take in Florida? Standard renewals typically take 30-45 days from complete submission. Expedited reviews for urgent situations are decided within 72 hours for commercial plans.

What if my IgG levels have dropped since starting Xembify? Include your physician's assessment and plan for dose adjustment. Declining levels don't automatically disqualify renewal if there's a clear clinical plan to optimize therapy.

Can I switch to a different SCIG product during renewal? Yes, but this typically requires a new prior authorization rather than a renewal. Your physician may need to demonstrate medical necessity for the specific product switch.

What happens if I miss the renewal deadline? Contact your provider immediately to request expedited processing. You may face a temporary coverage gap, so discuss bridge therapy options with your physician.

Does step therapy apply to Xembify renewals in Florida? Step therapy requirements vary by specific plan. Check your formulary document or contact member services to verify current requirements.

Can I appeal if Aetna switches me to a "preferred" SCIG product? Yes, you can request a formulary exception if there are clinical reasons you cannot use the preferred alternative. Include documentation of medical necessity for Xembify specifically.

What if my renewal is approved but at a lower dose? Work with your physician to either accept the approved dose with monitoring or appeal the dose limitation with clinical justification for the higher amount.

How do I know if my renewal was processed? Check your Aetna member portal, contact CVS Specialty Pharmacy about upcoming deliveries, or have your provider check the authorization status through their portal.
