When to Start Your Renewal Process

Gattex (teduglutide) renewals with Aetna CVS Health require advance planning. Most authorizations are granted for 12-month periods, but the renewal process should begin well before expiration.

Start 60-90 days early for these reasons:

  • Documentation gathering takes time, especially if you need updated labs or colonoscopy results
  • Processing typically takes 24-72 hours once complete documentation is received, but incomplete submissions cause delays
  • If denied, you'll need time for appeals before your current supply runs out
Tip: Set a calendar reminder for 90 days before your authorization expires. Your CVS Specialty Pharmacy team can help you identify the exact expiration date.

Red flags that signal you should start immediately:

  • You're within 30 days of expiration
  • Your insurance plan changed for the new year
  • You've missed any required safety monitoring appointments
  • Your parenteral nutrition needs have changed significantly

Required Documentation for Renewal

Aetna CVS Health requires specific evidence that Gattex therapy continues to provide clinical benefit. The documentation must demonstrate ongoing medical necessity for short bowel syndrome patients who depend on parenteral nutrition.

Clinical Response Evidence

Your renewal must include proof of therapeutic benefit, typically measured as:

  • ≥20% reduction in weekly parenteral nutrition or IV fluid volume from baseline (measured at weeks 16, 20, or 24 from initiation)
  • Decreased days per week requiring parenteral nutrition compared to pre-treatment
  • Documentation of improved nutritional status or quality of life measures

Medical Records Required

  • Updated letter of medical necessity from your gastroenterologist or treating specialist
  • Current parenteral nutrition logs showing volumes and frequency
  • Progress notes documenting clinical status and any side effects
  • Medication adherence records (must show ≥85% compliance)
  • Any hospitalizations or complications related to short bowel syndrome
Clinician Corner: The medical necessity letter should specifically address continued PN dependence, document any reduction in support needs, and confirm absence of contraindications like active malignancy or severe renal/hepatic impairment.

Safety Monitoring and Lab Requirements

Gattex requires ongoing safety monitoring, and missing these requirements is a common cause of renewal denials.

Required Every 6 Months

  • Alkaline phosphatase
  • Amylase
  • Lipase
  • Total bilirubin

Annual Requirements

  • Colonoscopy or alternative colon imaging (required within 6 months before starting Gattex, then annually for the first year, then every 5 years)
  • Fecal occult blood testing (especially important for pediatric patients)
Note: If any lab values are abnormal, additional diagnostic workup may be required before renewal approval. Plan extra time if your recent labs show concerning changes.

Submission Timeline and Process

Understanding Aetna CVS Health's renewal workflow helps ensure smooth approval without coverage gaps.

Submission Methods

  1. CVS Specialty Pharmacy coordination (recommended for existing patients)
  2. Aetna provider portal for prescribing physicians
  3. Fax submission to specialty precertification team
  4. Phone authorization at (866) 752-7021 for urgent situations

Processing Timeline

  • Standard processing: 24-72 hours once complete documentation received
  • Incomplete submissions: Can take 7-14 days with back-and-forth requests
  • Expedited reviews: Available for urgent medical situations (≤72 hours)

California-specific timing:

  • Pharmacy benefit staff available Monday-Friday 5 AM-10 PM, Saturday 6 AM-3 PM (Pacific)
  • Most authorizations completed within 24 hours when all documentation is provided

If Your Coverage Lapses

Coverage gaps can occur due to processing delays, incomplete documentation, or formulary changes. Since no FDA-approved alternatives exist for Gattex, the primary "bridge therapy" involves returning to intensive parenteral nutrition support.

Immediate Steps if Coverage Lapses

  1. Contact CVS Specialty Pharmacy immediately to request emergency supply or transition fill
  2. Coordinate with your care team to increase parenteral nutrition support
  3. Submit urgent appeal if the lapse was due to denial rather than processing delay
  4. Consider expedited review if interruption poses serious health risks

Bridge Therapy Options

  • Increased parenteral nutrition volume and frequency
  • Enhanced medical monitoring for nutritional status
  • Coordination with home infusion providers
  • No pharmacologic alternatives are available as bridge therapy
From our advocates: We've seen patients successfully maintain stability during short coverage gaps by working closely with their nutrition support team to temporarily increase PN support while appeals are processed. The key is immediate communication with all providers involved in your care.

Annual Formulary Changes to Watch

Aetna's formulary can change annually (effective January 1) and sometimes mid-year. For 2025, Gattex remains on specialty tiers across most Aetna plans, but specific requirements may shift.

What Changes Annually

  • Tier placement (affects copay amounts)
  • Prior authorization requirements (may become more or less stringent)
  • Step therapy protocols (required trial medications before Gattex)
  • Quantity limits (maximum doses per month)
  • Site of care restrictions (home vs. clinic administration)

How to Stay Informed

  • Review your plan's annual Summary of Benefits and Coverage
  • Check the current Aetna formulary for your specific plan
  • Contact member services if you receive notice of formulary changes

If Gattex moves to a higher tier or faces new restrictions:

  • Your doctor can request a formulary exception
  • Document medical necessity and lack of appropriate alternatives
  • Consider plan shopping during open enrollment if costs become prohibitive

California Appeal Rights and IMR Process

California offers robust appeal rights through the Department of Managed Health Care (DMHC), with particularly strong protections for specialty drug denials.

Internal Appeal Process

  1. File grievance with Aetna within 180 days of denial
  2. Wait up to 30 days for internal review decision
  3. Request expedited review if urgent (72 hours for urgent situations)

Independent Medical Review (IMR)

If Aetna upholds the denial, California residents can request IMR through DMHC:

  • Success rate: 68% of IMR requests result in patients receiving the denied service
  • Timeline: 45 days for standard IMR, 7 days for expedited
  • Cost: Free to patients (insurers pay review costs)
  • Binding decision: Aetna must comply with IMR determinations

How to File IMR

  1. Complete IMR application at healthhelp.ca.gov
  2. Submit supporting documentation (denial letters, medical records, physician statements)
  3. Include evidence of medical necessity specific to your short bowel syndrome
  4. Request expedited review if delay risks serious harm

DMHC Help Center: (888) 466-2219 for assistance with complaints and IMR applications.
