When to Start Your Renewal Process

Renewal Triggers and Early Warning Signs

Your Xembify authorization typically expires 12 months from the original approval date. Start preparing 60-90 days early if you notice:

  • Authorization expiration date approaching on your EOB statements
  • Pharmacy or infusion center mentioning upcoming renewal needs
  • Changes in your UnitedHealthcare plan (new formulary, different tier placement)
  • Recent hospitalizations or infections that might affect medical necessity
Tip: Set a calendar reminder 90 days before your authorization expires. UnitedHealthcare's OptumRx division processes renewals, and early submission prevents treatment interruptions.

Critical Timing Windows

90 days before expiration: Begin gathering updated documentation 60 days before expiration: Submit renewal request through provider 30 days before expiration: Follow up on pending decisions 7 days before expiration: Request expedited review if still pending

Coverage Gaps and Bridge Options

If Your Authorization Lapses

Immediate Actions:

  1. Contact your physician to request expedited renewal
  2. Ask pharmacy about emergency supply options
  3. Discuss IVIG bridge therapy if subcutaneous therapy must be delayed
  4. File expedited internal appeal if renewal is denied

Bridge Therapy Considerations

IVIG Infusion Options:

  • Hospital outpatient infusion centers
  • Physician office administration
  • Home infusion services (if available)
  • Temporary higher-dose IVIG to maintain levels

Coverage for Bridge Therapy: Most UnitedHealthcare plans cover medically necessary IVIG when SCIG is temporarily unavailable. Your physician should document the clinical need for continuous immunoglobulin replacement.

Emergency Access Protocols

For patients with severe primary immunodeficiency:

  • Contact UnitedHealthcare's urgent care line
  • Request 30-day emergency supply while renewal processes
  • Document any infections or complications during coverage gaps

Annual Plan Changes to Monitor

Formulary Updates

Check annually for:

  • Xembify formulary tier changes

  • Quantity limit modifications

Where to Verify: UnitedHealthcare's online formulary lookup tool or your plan's Prescription Drug List (PDL)

Plan Design Changes

Review these elements:

  • Prior authorization requirements (may change yearly)
  • Site of care restrictions (home vs. clinic administration)
  • Specialty pharmacy network changes
  • Copayment or coinsurance adjustments

OptumRx Policy Updates

UnitedHealthcare's pharmacy benefit manager regularly updates coverage policies. Recent changes include eliminating reauthorization requirements for some chronic medications, though Xembify still requires annual renewal as of 2025.

From our advocates: "We've seen many Xembify renewals initially denied for 'insufficient infection documentation' get approved on appeal when families submitted detailed infection logs with dates, treatments, and outcomes. The key is showing the clear difference in infection frequency before and after starting Xembify. Keep detailed records throughout your treatment year – it makes renewal much smoother."

When to Escalate

Contact the NC Department of Insurance if UnitedHealthcare:

  • Misses appeal deadlines
  • Denies without proper clinical review
  • Fails to honor external review decisions
  • Creates procedural barriers to appeals

FAQ

How long does UnitedHealthcare take to process Xembify renewals? Standard renewals take 5-10 business days for complete submissions. Expedited reviews are processed within 72 hours for urgent medical needs.

What if my IgG levels are above normal range? Document that higher levels are medically necessary for your specific condition. Some patients require IgG levels above normal range to prevent infections.

Can I switch from Xembify to another SCIG product during renewal? Yes, but this may require new prior authorization. Discuss alternatives like Hizentra or Cuvitru with your physician if Xembify access becomes difficult.

Does UnitedHealthcare require step therapy for Xembify renewals? Generally no for established patients, but new step therapy requirements could be implemented. Check current formulary status annually.

What documentation proves medical necessity for renewal? Recent IgG levels, infection history comparison, treatment response evidence, and physician attestation of continued need for immunoglobulin replacement.

Can I get a 90-day supply while renewal is pending? Ask your pharmacy about emergency supplies. UnitedHealthcare may approve temporary supplies for established patients while processing renewals.

What if I've moved to North Carolina from another state? Submit new prior authorization with complete clinical history. Out-of-state treatment records are acceptable documentation for North Carolina renewals.
