When to Start Your Renewal

UnitedHealthcare requires annual prior authorization renewal for Xembify, typically 12 months from your initial approval date. The golden rule: start 60-90 days early to prevent any gap in coverage.

Renewal Triggers

  • Check your EOB statements for expiration dates
  • Set calendar reminders 90 days before expiration
  • Monitor pharmacy notifications from CVS Specialty or your infusion provider
  • Watch for plan year changes (January 1st often brings new requirements)
Tip: If you're approaching your expiration within 14 days and haven't started renewal, request expedited processing by calling UnitedHealthcare at 1-800-711-4555 and emphasizing medical urgency.

Required Documentation Package

Your renewal success depends on comprehensive, up-to-date clinical documentation. Here's what UnitedHealthcare OptumRx requires:

Core Clinical Records

  • Recent IgG trough levels (within 90 days of submission)
  • Infection log documenting frequency and severity since last approval
  • Current diagnosis confirmation with ICD-10 codes (typically D80.9 for primary immunodeficiency)
  • Weight-based dosing schedule and any adjustments made
  • Treatment response assessment including quality of life improvements

Administrative Requirements

  • UHC Prior Authorization Renewal Form (available through provider portal)
  • Updated insurance and member information
  • Pharmacy or infusion center details with contact information
  • Prescriber information including NPI and DEA numbers

Physician's Letter of Medical Necessity

Your doctor's letter should include:

  1. Primary immunodeficiency diagnosis with supporting lab values
  2. Treatment history since last approval, including response to therapy
  3. IgG target levels and current dosing rationale
  4. Evidence of ongoing medical necessity for SCIG continuation
  5. Risk assessment if therapy is interrupted

If Your Approval Lapses: Bridge Options

Immediate Actions (Within 24 Hours)

  1. Contact your prescribing physician to discuss temporary alternatives
  2. Call CVS Specialty Pharmacy at 1-800-237-2767 for emergency supply options
  3. Request expedited prior authorization with clinical urgency documentation

Bridge Therapy Options

Your physician may recommend:

  • Temporary IVIG therapy administered via hospital outpatient or infusion center
  • Emergency SCIG supply from specialty pharmacy programs
  • Adjusted dosing schedule if clinically appropriate for short-term gaps
  • Prophylactic antibiotics for high-risk patients during coverage gaps

Important: These are medical decisions that should only be made by your healthcare team. Insurance companies cannot dictate which bridge therapy is appropriate for your condition.

Appeals Process in Michigan

Michigan patients have robust appeal rights under the Patient's Right to Independent Review Act. If UnitedHealthcare denies your Xembify renewal, here's your roadmap:

Internal Appeals (First Step)

  • Timeline: 180 days from denial to file
  • Submit through: UHC Provider Portal or member services
  • Include: Enhanced clinical documentation addressing specific denial reasons

Michigan DIFS External Review

After exhausting internal appeals, Michigan residents can file for external review:

  • Filing deadline: 127 days from final internal denial
  • Standard timeline: 60 days maximum for decision
  • Expedited timeline: 72 hours for urgent cases

How to File External Review

Online: DIFS External Review Portal Phone: 877-999-6442 (8am-5pm, Monday-Friday) Required documents:

  • FIS 0018 External Review Form
  • UnitedHealthcare denial letter
  • Supporting medical records
  • Physician letter for expedited review (if urgent)
Key Advantage: DIFS decisions are binding on UnitedHealthcare. If the independent medical review overturns the denial, your insurer must comply.

FAQ

Q: How long does UnitedHealthcare take to process Xembify renewals? A: Standard renewals typically take 3-5 business days when submitted with complete documentation through the provider portal. Start 60-90 days early to ensure no treatment gaps.

Q: What if my IgG levels have changed since last approval? A: Include recent lab results (within 90 days) and have your physician explain any dosing adjustments in the medical necessity letter. Changes in levels often support continued therapy need.

Q: Can I switch from Xembify to another SCIG product during renewal? A: Switching products requires a new prior authorization. Check if your plan has step therapy requirements between SCIG brands like Hizentra or Cuvitru.

Q: What counts as "expedited" review in Michigan? A: Situations where delay would seriously jeopardize your health, substantiated by your physician. This includes active infections, recent hospitalizations, or impending immune compromise.

Q: Does UnitedHealthcare require step therapy for Xembify renewals? A: Generally not for existing patients, but verify your specific plan's requirements. New patients may need to try IVIG first unless contraindicated.

Q: What if I'm switching UnitedHealthcare plans in 2025? A: Your approval may not transfer between plan types. Start the process early and verify Xembify's formulary status on your new plan.
