Renewal Timing & Triggers

UnitedHealthcare typically approves Tavalisse for 12-month periods for chronic immune thrombocytopenia (ITP), requiring renewal documentation to continue coverage. Here's when to start preparing:

Critical Timelines

Action When to Complete Why It Matters
Begin gathering evidence 60 days before expiration Allows time for lab scheduling, chart notes
Submit renewal request 30 days before expiration UHC policy requirement
Follow up if no response 15 days before expiration Prevents treatment interruption
Appeal deadline (if denied) 180 days from denial Washington state requirement

Early Warning Signs to Renew

Start your renewal process immediately if you notice:

  • Current authorization expires within 90 days
  • Platelet counts have fluctuated significantly
  • New side effects requiring dose adjustments
  • Changes in your UnitedHealthcare plan (job change, open enrollment)
  • Prior therapy documentation is outdated (>2 years old)
Tip: Set a calendar reminder for 75 days before your current approval expires. This gives you buffer time if labs are delayed or your hematologist needs additional documentation.

Evidence Requirements for 2025

UnitedHealthcare's 2025 renewal criteria focus on documented clinical response and ongoing medical necessity. Based on current UHC prior authorization policies, you'll need:

Required Clinical Documentation

Diagnosis Confirmation

  • Chronic immune thrombocytopenia (ICD-10: D69.3)
  • Duration >12 months documented in medical record
  • Exclusion of secondary causes (medication-induced, viral, autoimmune)

Treatment Response Evidence

  • Baseline platelet count before starting Tavalisse
  • Current platelet levels showing improvement to ≥30,000-50,000/μL
  • Trend over the past 12 months demonstrating sustained response
  • Documentation of reduced bleeding episodes or transfusion needs

Safety Monitoring Results

  • Liver function tests (AST, ALT, bilirubin) - must be <3x upper limit normal
  • Blood pressure readings - controlled <160/100 mmHg per FDA labeling
  • Complete blood count showing adequate neutrophil count
  • Documentation of any dose adjustments for adverse events

Prescriber Requirements

  • Board-certified hematologist or consultation documented
  • Medical necessity letter explaining why Tavalisse remains appropriate
  • Prior therapy documentation (corticosteroids, IVIG, TPO receptor agonists) and why alternatives failed or aren't suitable

  • Update medical necessity letter with current clinical status
  • Obtain recent lab results (within 30 days)
  • Document current dose and any modifications

3. Submit Complete Package (Same day)

Note: Submit renewal requests as early as possible. UnitedHealthcare processes thousands of specialty drug renewals, and submissions closer to expiration may face delays.

Common Denial Reasons & Solutions

Based on UHC denial patterns and renewal requirements, here are the most frequent issues:

Denial Reason Documentation Solution Timeline to Fix
Insufficient response documentation Provide platelet count trend showing improvement from baseline 3-5 days
Missing safety labs Submit recent LFTs, CBC, BP readings within 30 days 1-2 days
Prescriber not hematologist Obtain hematology consultation note or co-signature 1-2 weeks
Prior therapies not documented Provide records of failed corticosteroids, IVIG, or TPO-RA trials 3-7 days
Formulary tier change Request formulary exception with medical necessity justification 1-2 weeks

Scripts for Common Situations

Calling UHC for Renewal Status: "I'm calling to check the status of a Tavalisse renewal prior authorization for [patient name], member ID [number]. The current authorization expires on [date] and we submitted renewal documentation on [date]. Can you confirm receipt and provide an expected decision timeline?"

Requesting Expedited Review: "This patient has chronic ITP with platelet counts that could drop to dangerous levels without continued Tavalisse therapy. We're requesting expedited review due to risk of serious bleeding if treatment is interrupted."

Washington Appeals Process

If UnitedHealthcare denies your Tavalisse renewal, Washington state provides strong consumer protections through multiple appeal levels.

Internal Appeals

Timeline: File within 180 days of denial notice Decision: 30 days for standard review, 72 hours for urgent cases How to File:

  • Online through UHC member portal
  • Mail to address on denial letter
  • Fax with delivery confirmation

External Review (Independent Review Organization)

When Available: After final internal denial or if UHC misses deadlines Timeline: Request within 120 days of final internal denial Decision: 45 days standard, 72 hours expedited Oversight: Washington Office of the Insurance Commissioner

To Request External Review:

  1. Contact Washington OIC Consumer Advocacy: 1-800-562-6900
  2. Submit external review request form
  3. Include all denial letters and supporting documentation
  4. Request expedited review if medically urgent
From our advocates: We've seen many successful Tavalisse appeals in Washington when patients include comprehensive platelet count trends and detailed letters explaining why formulary alternatives failed. The key is showing clear clinical benefit and ongoing medical necessity. Always keep copies of everything you submit.

Expedited Appeals for Urgent Situations

Request expedited review if:

  • Current platelet count is dangerously low (<20,000/μL)
  • History of serious bleeding episodes
  • Risk of treatment interruption could cause immediate harm

Your hematologist should provide written certification that delay would "seriously jeopardize life, health, or ability to regain maximum function."

Cost Considerations & Support

Annual Plan Changes to Monitor

FAQ

How long does UnitedHealthcare take to process Tavalisse renewals? Standard renewals take up to 15 business days. Expedited reviews for urgent medical situations are decided within 24-72 hours.

What if my platelet counts fluctuated during the renewal period? Document the overall trend and provide context. Include any dose adjustments made and current stability. Temporary fluctuations don't automatically disqualify renewal if overall response is maintained.

Can I request renewal before my current authorization expires? Yes, submit renewal requests 30-60 days early. UnitedHealthcare will not approve overlapping authorizations, but early submission prevents gaps in coverage.

What happens if UnitedHealthcare changes Tavalisse's formulary status? You can request a formulary exception with your renewal. Include documentation that formulary alternatives are inappropriate or have failed previously.

Do I need new prior therapy documentation for renewal? Generally no, if your original approval included adequate documentation of failed therapies. However, if it's been over 2 years, updated documentation may strengthen your renewal.

What if my hematologist is no longer in-network? You can request a continuity of care exception to continue with your current hematologist, or obtain a consultation note from an in-network hematologist supporting continued Tavalisse therapy.
