How to Get Xembify (Immune Globulin SC) Covered by Florida Blue Cross Blue Shield: Prior Authorization, Appeals, and Alternative Options Guide

Quick Answer: Xembify (immune globulin SC) requires prior authorization from Florida Blue Cross Blue Shield for primary immunodeficiency. Submit PA 60-75 days before needed with diagnosis labs (low IgG), infection history, and failed IVIG/SCIG trials. If denied, you have 180 days to appeal internally, then external review through Florida DFS. Start by checking your specific plan's formulary at myhealthtoolkitfl.com and contacting your prescriber for PA submission.

When Alternatives Make Sense

Florida Blue typically requires trials of preferred immune globulin products before approving Xembify due to step therapy requirements. This makes clinical sense when:

  • You're newly diagnosed with primary immunodeficiency and haven't tried other IVIG or SCIG products
  • Cost considerations matter for your specific plan (Xembify often carries higher copays as non-preferred)
  • Clinical equivalency exists—most immune globulins provide similar IgG replacement for primary immunodeficiency

However, alternatives may not be appropriate if you have:

  • Documented allergic reactions to preferred products (IgA deficiency, specific excipient sensitivities)
  • Access issues with infusion centers for IVIG products
  • Lifestyle factors requiring home-based subcutaneous therapy specifically
Note: Even with step therapy requirements, you can request exceptions based on medical contraindications or prior treatment failures from other insurers.

Typical Xembify Alternatives

Florida Blue's preferred immune globulin products vary by plan, but commonly include:

IVIG (Intravenous) Options

  • Gamunex-C (10% liquid)
  • Privigen (10% liquid)
  • Gammaked (10% liquid)

SCIG (Subcutaneous) Options

  • Hizentra (20% liquid)
  • Cuvitru (20% liquid)
  • HyQvia (facilitated SCIG with hyaluronidase)

Pros and Cons Overview

Route Advantages Considerations
IVIG Monthly dosing, established efficacy, often preferred tier Requires IV access, infusion center visits, systemic reactions
SCIG Home administration, fewer systemic reactions, steady levels Weekly/bi-weekly injections, local site reactions, higher volume

Access Considerations: IVIG requires infusion center scheduling and IV access, while SCIG allows home administration but requires patient/caregiver training and specialty pharmacy coordination.

Exception Strategy for Non-Preferred Status

When Xembify appears non-preferred on your formulary, request a formulary exception with these evidence types:

Medical Necessity Documentation

  • Prior treatment failures: Document inadequate response or intolerance to preferred IVIG and SCIG options
  • Clinical contraindications: IgA deficiency requiring IgA-depleted products, venous access issues preventing IVIG
  • Lifestyle factors: Home-based therapy requirements due to work/family obligations

Supporting Evidence to Include

  • Peer-reviewed literature supporting Xembify for your specific condition
  • FDA labeling information for approved indications
  • Clinical guidelines from AAAAI or other immunology societies
  • Previous insurance approvals for Xembify (if switching plans)
Tip: Florida Blue must respond to formulary exception requests within 72 hours for urgent cases or 2 business days for standard requests per state regulations.

Switching Logistics and Coordination

From IVIG to Xembify (SCIG)

Dosing Conversion: Start Xembify 1 week after last IVIG dose. Convert monthly IVIG dose to weekly SCIG using 1.37x factor (e.g., 30g IVIG monthly = ~41g Xembify monthly, or ~10g weekly).

Coordination Steps:

  1. Provider coordination: Schedule overlap visit to review injection technique
  2. Specialty pharmacy: Arrange Xembify delivery and supplies (needles, infusion pumps)
  3. Insurance: Ensure PA covers new product and administration supplies
  4. Monitoring: Check IgG trough levels 4-8 weeks after switch

From Other SCIG to Xembify

Direct switch possible at same dose/frequency. Monitor for:

  • Local site reactions (may differ between products)
  • Injection volume tolerance
  • Patient preference for viscosity/injection experience
From Our Advocates: A composite case showed that patients switching from Hizentra to Xembify often needed needle length adjustments (9mm to 12mm) and slower initial infusion rates to minimize local reactions. Working closely with the specialty pharmacy's nursing team during the first month helped optimize the injection experience.

Re-trying for Xembify Later

If initially denied or you start with an alternative, document these factors for future Xembify appeals:

During Alternative Therapy

  • Efficacy measures: IgG trough levels, infection frequency, hospitalization rates
  • Tolerability issues: Infusion reactions, site reactions, quality of life impacts
  • Adherence challenges: Missed doses due to access issues, lifestyle conflicts

Triggering Events for Re-appeal

  • Treatment failure: Breakthrough infections despite adequate IgG levels
  • Intolerable side effects: Persistent reactions affecting quality of life
  • Access problems: Infusion center closures, insurance network changes
  • Plan year changes: New formulary may have different tier status

Documentation Timeline: Keep detailed logs for 3-6 months of alternative therapy to build a strong case for medical necessity.
