UnitedHealthcare Policy Overview

UnitedHealthcare requires prior authorization for all tafamidis products (Vyndaqel and Vyndamax) across commercial, Medicare Advantage, and Medicaid plans. The drug is managed through OptumRx's specialty pharmacy program with strict medical necessity criteria.

Coverage Across Plan Types

  • Commercial Plans: Standard PA requirements with 12-month authorization periods
  • Medicare Advantage: Enhanced scrutiny with periodic reauthorization
  • Medicaid: State-specific criteria may apply alongside federal requirements
Note: As of December 31, 2025, Vyndaqel will be discontinued for UHC Medicare plans, with existing authorizations transitioning to Vyndamax without new PA requirements.

Medical Necessity Requirements

Core Eligibility Criteria

UnitedHealthcare's medical necessity criteria for tafamidis include:

Confirmed ATTR-CM Diagnosis (one of the following):

  • Pathogenic TTR gene mutation with genetic documentation
  • Histologic confirmation via cardiac or non-cardiac tissue biopsy
  • Non-invasive pathway: Echocardiogram/cardiac MRI showing amyloid features PLUS technetium pyrophosphate (PYP) scan with grade 2 or 3 cardiac uptake

Functional Status Requirements:

  • NYHA Class I, II, or III heart failure symptoms
  • Documented history of heart failure or ongoing symptoms (dyspnea, edema)

Exclusion Criteria:

  • Must exclude amyloid light chain (AL) amyloidosis via negative serum and urine immunofixation

Step Therapy and Exceptions

Good news: UnitedHealthcare does not require step therapy with other heart failure medications for tafamidis. Coverage is based directly on confirmed ATTR-CM diagnosis and disease severity.

However, individual member benefit plans may have additional requirements. Always verify your specific plan language through the member portal or by calling customer service.

Quantity Limits and Renewal Requirements

Quantity Limits

  • Standard limit: 30 tablets per month (one month's supply)
  • Vyndamax: 61 mg once daily (30 capsules/month)
  • Vyndaqel: 80 mg daily as four 20 mg capsules (120 capsules/month)

Renewal Process

  • Initial authorization: 12 months
  • Reauthorization required: Submit 30 days before expiration
  • Renewal criteria: Document continued NYHA Class I-III status and clinical benefit
Tip: Set calendar reminders 45 days before your authorization expires to ensure uninterrupted coverage.

Required Diagnostics and Documentation

Essential Documentation Checklist

Diagnostic Proof (submit one):

  • Cardiac biopsy pathology report confirming ATTR deposits
  • PYP scan report showing grade 2 or 3 cardiac uptake
  • Genetic testing confirming pathogenic TTR mutation

Supporting Clinical Evidence:

  • Echocardiogram or cardiac MRI showing increased wall thickness
  • NYHA functional class assessment by cardiologist
  • Heart failure symptom documentation

Laboratory Requirements:

  • Serum free light chain assay (negative)
  • Serum and urine immunofixation (negative)
  • Results must be recent (typically within 6 months)

Specialty Pharmacy Routing

Tafamidis must be dispensed through OptumRx Specialty Pharmacy. Retail pharmacies cannot fill these prescriptions.

Routing Process

  1. Provider submits PA through UHC Provider Portal
  2. Upon approval, prescription automatically routes to OptumRx Specialty
  3. OptumRx contacts patient to coordinate delivery
  4. Monthly refills processed automatically with active authorization
Important: Attempting to fill at retail pharmacies will result in claim rejection.

Evidence to Support Medical Necessity

Key Clinical Guidelines to Reference

FDA Labeling: Tafamidis is indicated for ATTR-CM to reduce cardiovascular mortality and hospitalization in adults.

Professional Society Guidelines:

  • American Heart Association/American College of Cardiology guidelines support tafamidis for confirmed ATTR-CM
  • European Society of Cardiology recommendations for TTR stabilizers

Clinical Evidence:

  • ATTR-ACT trial demonstrated 37% reduction in cardiovascular-related hospitalizations
  • Greatest efficacy shown in NYHA Class I and II patients

Sample Medical Necessity Narrative

Clinician Corner: Medical Necessity Letter Template

"Patient has confirmed transthyretin amyloid cardiomyopathy (ATTR-CM) as evidenced by [PYP scan showing grade 3 uptake/cardiac biopsy/genetic testing]. Amyloid light chain disease has been excluded via negative serum and urine immunofixation. Patient presents with NYHA Class [I/II/III] heart failure symptoms including [specific symptoms]. Tafamidis is FDA-approved and guideline-recommended for this indication to reduce cardiovascular mortality and hospitalizations. No contraindications exist, and the patient is not receiving competing amyloidosis treatments."

Appeals Process in Washington

Internal Appeals Timeline

  • Deadline: 60 calendar days from denial letter
  • Decision timeframe: 28 calendar days (standard) or 72 hours (expedited)
  • How to file: Phone (1-877-542-8997), online portal, or written submission

External Independent Review Organization (IRO)

If UnitedHealthcare upholds the denial, Washington residents can request external review:

Process:

  1. Request IRO review within 180 days of final internal denial
  2. Submit to Washington Office of the Insurance Commissioner
  3. IRO decision is binding on the health plan
  4. No cost to patient or provider

Timeline: 30 days for standard review, 72 hours for expedited

From our advocates: "We've seen several Washington patients successfully overturn tafamidis denials through IRO review by emphasizing the drug's unique mechanism and lack of therapeutic alternatives for ATTR-CM. The key is presenting clear diagnostic evidence and clinical rationale in the initial submission."

Common Denial Reasons and Solutions

"Experimental/investigational" Reference FDA approval and clinical guidelines FDA label, AHA/ACC guidelines

FAQ

How long does UnitedHealthcare PA take in Washington? Standard PA decisions are made within 14 business days. Expedited reviews (for urgent cases) are completed within 72 hours.

What if tafamidis is non-formulary on my plan? Non-formulary drugs can still be covered with prior authorization and medical necessity documentation. Appeal if initially denied.

Can I request an expedited appeal? Yes, if your health could be seriously jeopardized by delays. Call 1-877-542-8997 to request expedited review.

Does step therapy apply if I've failed other treatments outside Washington? UnitedHealthcare doesn't require step therapy for tafamidis, but document any previous heart failure treatments and their outcomes.

What happens if my cardiologist isn't in-network? Tafamidis requires cardiology oversight. If your cardiologist is out-of-network, request a single-case agreement or seek an in-network specialist consultation.

How do I check my authorization status? Log into the UnitedHealthcare member portal or call customer service. Your pharmacy can also check authorization status.
