Understanding Your Denial Letter

When UnitedHealthcare denies Daybue coverage, your denial letter will contain specific reason codes. Here's how to decode the most common ones:

Medical Necessity Denials:

  • "Not medically necessary" typically means missing clinical documentation
  • "Experimental/investigational" suggests the reviewer didn't recognize FDA approval
  • "Age restriction" indicates patient under 2 years old

Administrative Denials:

  • "Prior authorization required" means the prescription was submitted without PA
  • "Non-formulary" indicates Daybue isn't on your plan's preferred drug list
  • "Quantity limits exceeded" relates to dosing calculations
Tip: Circle the exact denial reason and deadline date on your letter—you'll need both for your appeal.

Common Fixable Issues

Before filing an appeal, check if your denial stems from easily correctable problems:

Missing Documentation

  • Genetic testing results: MECP2 mutation confirmation
  • Specialist notes: Recent neurology evaluation (within 6 months)
  • Clinical severity scores: Rett Syndrome Behaviour Questionnaire (RSBQ) baseline
  • Weight-based dosing: Calculation showing appropriate dose per FDA labeling

Coding Issues

  • Wrong diagnosis code: Ensure ICD-10 code F84.2 (Rett syndrome) is used
  • Prescriber specialty: Must be neurology or pediatric neurology
  • Site of care: Home administration vs. clinical setting documentation

Policy Misunderstandings

  • Step therapy: Daybue is first-line therapy—no alternatives exist
  • Age requirements: Confirm patient is ≥2 years with birth certificate if needed

First-Level Appeal Strategy

UnitedHealthcare allows 180 days from your denial date to file an internal appeal. Here's your step-by-step approach:

1. Gather Required Documents

  • Original denial letter
  • Complete medical records (last 12 months)
  • Genetic testing confirming MECP2 mutation
  • Current neurologist evaluation
  • FDA prescribing information for Daybue
  • Clinical trial data (LAVENDER study results)

2. Structure Your Appeal Letter

Your appeal should address each denial reason point-by-point:

Opening paragraph: State you're formally appealing the denial of Daybue for [patient name], member ID [number], and reference the original denial date.

Medical necessity section: Explain why Daybue is the only FDA-approved treatment for Rett syndrome, with no therapeutic alternatives.

Clinical evidence: Include RSBQ scores, functional assessments, and documentation of symptom severity.

Regulatory compliance: Cite FDA approval (March 2023) and appropriate prescribing per label.

3. Submit Your Appeal

  • Online: UnitedHealthcare member portal (fastest processing)
  • Fax: Check your denial letter for plan-specific fax number
  • Mail: Send certified mail to address on denial letter
Note: Keep copies of everything and request delivery confirmation.

Peer-to-Peer Review Process

Request a peer-to-peer call between your neurologist and UnitedHealthcare's medical director. This often resolves denials faster than written appeals.

Scheduling the Call

  1. Call UnitedHealthcare provider services
  2. Request "peer-to-peer review for Daybue denial"
  3. Provide case reference number from denial letter
  4. Confirm neurologist's availability within 24-48 hours

Preparation Checklist for Your Doctor

  • Patient's complete Rett syndrome history
  • Genetic testing results and interpretation
  • Current functional status and treatment goals
  • FDA approval rationale and clinical trial outcomes
  • Lack of therapeutic alternatives

Key Talking Points

  • Daybue is the only FDA-approved Rett syndrome therapy
  • Patient meets all label criteria (age, diagnosis, prescriber specialty)
  • Clinical trials showed significant improvement in RSBQ scores
  • No contraindications or safety concerns for this patient

External Review in Texas

If UnitedHealthcare upholds their denial after internal appeals, Texas law provides access to Independent Review Organizations (IROs).

Eligibility Requirements

  • Completed UnitedHealthcare's internal appeal process
  • Denial based on medical necessity, appropriateness, or experimental/investigational designation
  • Request filed within 4 months of final internal denial

How to Request IRO Review

  1. Get the form: UnitedHealthcare must provide IRO request form with final denial
  2. Complete documentation: Include all medical records and appeal history
  3. Submit to TDI: Texas Department of Insurance processes all IRO requests
  4. Timeline: Standard reviews completed within 20 days; urgent cases within 5 days

Contact Information

Important: IRO decisions are binding—if they overturn UnitedHealthcare's denial, coverage must be provided.

Medical Necessity Letter Template

Use this template for your neurologist to write a compelling medical necessity letter:

[Date]

UnitedHealthcare Appeals Department
Re: Medical Necessity Appeal for Daybue (trofinetide)
Patient: [Name], DOB: [Date], Member ID: [Number]

Dear Medical Director,

I am writing to strongly support coverage of Daybue (trofinetide) for my patient with genetically confirmed Rett syndrome. This medication is medically necessary and represents the first and only FDA-approved treatment for this devastating condition.

Clinical History:
[Patient name] is a [age]-year-old [gender] with Rett syndrome confirmed by genetic testing showing a pathogenic MECP2 mutation. The patient exhibits classic Rett syndrome features including [list specific symptoms: regression, seizures, breathing abnormalities, motor dysfunction]. Current RSBQ score is [number], indicating [severity level].

Treatment Rationale:
Daybue demonstrated significant efficacy in the pivotal LAVENDER trial, with 38% of patients showing improvement versus 15% on placebo. Caregiver-reported RSBQ scores improved by 4.9 points over 12 weeks. There are no alternative FDA-approved therapies for Rett syndrome—supportive care alone cannot address the underlying pathophysiology.

Treatment Goals:
Our goals include reducing symptom burden, improving quality of life, and potentially slowing disease progression. We will monitor response using serial RSBQ assessments and regular clinical evaluations.

Supporting Documentation Attached:

  • Genetic test results confirming MECP2 mutation
  • Baseline RSBQ and clinical severity scores
  • Recent neurology consultation notes
  • FDA prescribing information
  • Relevant clinical trial publications

Conclusion:
This patient meets all FDA criteria for Daybue therapy. Denial of coverage would compromise their health and functional outcomes. I strongly urge approval of this medically necessary treatment.

Sincerely,
[Neurologist Name, MD]
[Contact Information]

FAQ

How long does UnitedHealthcare prior authorization take in Texas?
Standard PA requests are processed within 15 days, while urgent requests receive decisions within 72 hours. Missing documentation can extend these timelines.

What if Daybue is non-formulary on my plan?
Request a formulary exception with medical necessity documentation. Since Daybue is the only FDA-approved Rett syndrome treatment, exceptions are often granted.

Can I request an expedited appeal?
Yes, if delays would jeopardize your health. Both internal appeals and IRO reviews offer expedited processing for urgent medical situations.

Does step therapy apply to Daybue?
No, step therapy typically doesn't apply since Daybue is the first and only approved Rett syndrome therapy. Document this in your appeal if step therapy is cited as a denial reason.

What happens if I move to another state during my appeal?
Texas IRO decisions remain valid, but future appeals would follow your new state's process. Maintain all Texas appeal documentation for continuity.

How much does Daybue cost without insurance?
The list price is approximately $21.10 per mL, with total monthly costs varying based on weight-based dosing (typically $9,000-15,000+ per month).

Can I appeal on behalf of my child?
Yes, parents and legal guardians can file appeals for minor children. Include proof of guardianship with your appeal documents.

What if my neurologist won't write a medical necessity letter?
Seek a second opinion from another pediatric neurologist or Rett syndrome specialist. The prescribing physician's support is crucial for appeal success.
