Renewal Triggers: When to Start

30-Day Rule

Start your Bylvay renewal process 30 days before your current authorization expires. Aetna CVS Health requires this lead time to prevent treatment interruption, especially for specialty medications dispensed through their specialty pharmacy network.

Early Warning Signs

Begin renewal preparation if you notice:

  • Authorization expiration date approaching on your CVS Specialty pharmacy bottles
  • Calls from CVS Specialty about upcoming renewal needs
  • Changes in your insurance plan (job change, plan renewal, formulary updates)
  • Any gaps in treatment or missed doses that might affect response documentation
Tip: Set a calendar reminder 45 days before expiration to gather documents early.

Evidence Update: Documenting Treatment Response

Required Lab Monitoring

Aetna requires specific lab evidence to demonstrate both safety and efficacy:

Liver Function Tests (within 3 months):

  • ALT, AST levels
  • Total and direct bilirubin
  • INR (as surrogate for vitamin K status)

Fat-Soluble Vitamin Levels (within 3 months):

  • Vitamin A, D, E levels
  • Document any supplementation provided
  • Show stable or improving levels

Pruritus Assessment Documentation

Your specialist must document improvement using validated scales:

  • Observer-Reported Outcome (ObsRO) scores from caregivers
  • 0-4 scale documentation (0 = no scratching, 4 = worst possible)
  • Target: sustained scores ≤1 or ≥1-point improvement from baseline
  • Include impact on sleep quality and daily activities

Clinical Response Markers

Document these additional response indicators:

  • Reduced serum bile acid levels (if monitored)
  • No new portal hypertension signs
  • Stable growth parameters in pediatric patients
  • Maintained school/work attendance
Note: Counterforce Health specializes in helping patients compile exactly this type of clinical evidence for specialty drug renewals, turning complex medical data into compelling appeals that speak directly to payer requirements.

Renewal Packet: Required Documentation

Letter of Medical Necessity Update

Your prescriber should include:

  1. Current clinical status compared to pre-treatment baseline
  2. Quantified improvement in pruritus scores and quality of life
  3. Safety monitoring results showing no concerning trends
  4. Continued medical necessity with specialist attestation
  5. Alternative therapy assessment (why other options remain inadequate)

Timeline: Submission to Decision

Standard Process Timeline

  • Day 1: Submit complete renewal packet
  • Days 1-3: Aetna processes and assigns for clinical review
  • Days 4-30: Clinical review and determination
  • Day 30: Decision notification (approval or denial)

Expedited Review Option

For urgent renewals (risk of treatment interruption):

  • Requires prescriber attestation of medical urgency
  • Submit through Aetna provider portal or call Member Services

What Affects Timeline

Delays commonly occur due to:

  • Missing lab results or outdated tests
  • Incomplete specialist documentation
  • Need for additional clinical information
  • Payer requests for peer-to-peer review

If Coverage Lapses: Bridge Options

Immediate Steps

  1. Contact CVS Specialty immediately to report the lapse
  2. Request emergency supply (usually 3-7 days while appealing)
  3. File expedited appeal if renewal was denied
  4. Explore manufacturer assistance through Ipsen's patient support program

Bridge Therapy Considerations

Work with your specialist to evaluate:

  • Ursodeoxycholic acid (UDCA) for temporary cholestasis management
  • Supportive care measures for pruritus (antihistamines, topical treatments)
  • Bile acid sequestrants if previously tolerated
Important: Don't stop Bylvay abruptly without specialist guidance, as pruritus may return quickly.

Check for changes in:

  • Formulary status (tier placement, coverage restrictions)
  • Prior authorization criteria (new requirements or documentation)
  • Specialty pharmacy network (preferred dispensing locations)

Appeals Process in Washington

Internal Appeals with Aetna

If your renewal is denied:

  1. File within 180 days of denial notice
  2. Submit additional evidence not in original packet
  3. Request expedited review if medically urgent
  4. Expect decision within 30 days (72 hours if expedited)

External Review Through Washington's IRO

After exhausting internal appeals:

  1. Request external review through Aetna within 4 months
  2. Aetna forwards to Washington's IRO portal within 3 business days
  3. Submit additional documentation within 5 business days to IRO
  4. Independent specialist panel reviews your case
  5. Binding decision issued within 30 days (72 hours if expedited)

The IRO decision is final and binding on Aetna. If approved, they must cover your treatment and pay for the review process.

When dealing with complex specialty drug appeals like Bylvay renewals, Counterforce Health helps patients and clinicians navigate both internal and external review processes by crafting evidence-based appeals that directly address payer-specific criteria and Washington's regulatory requirements.

From our advocates: We've seen many families successfully renew Bylvay coverage by staying ahead of the timeline and maintaining detailed pruritus logs. One caregiver created a simple daily chart tracking scratching episodes and sleep disruption—this documentation proved crucial when Aetna initially questioned continued medical necessity. The key is consistent, objective measurement that clearly shows ongoing benefit.

FAQ

How long does Aetna typically approve Bylvay renewals? Most renewals are approved for 12 months when clinical criteria are met, though initial approvals may be shorter (3-6 months) to establish response.

What if my labs show some abnormalities? Minor elevations may not disqualify renewal if they're stable and being monitored. Your specialist should address any abnormalities in the renewal letter with a management plan.

Can I switch from CVS Specialty to another pharmacy? Bylvay requires specialty pharmacy dispensing. You may be able to use other Aetna-contracted specialty pharmacies, but confirm coverage and logistics first.

What happens if Washington's external review upholds the denial? The IRO decision is binding, but you can still explore manufacturer assistance programs, clinical trials, or legal consultation for exceptional circumstances.

Does step therapy apply to Bylvay renewals? If you're already established on Bylvay, step therapy typically doesn't apply to renewals. However, plan changes might trigger new requirements.

How do I get expedited review for urgent renewals? Your prescriber must attest that delay would seriously jeopardize your health. Submit this request through Aetna's provider portal or by calling Member Services.
