Submit 60 days before expiration through CVS Caremark or your provider portal. If denied, Washington residents have strong appeal rights including binding external review within 180 days.

Renewal Triggers: When to Start the Process

Your Prolastin-C renewal isn't automatic. Aetna requires reauthorization to confirm you still meet clinical criteria and the medication provides ongoing benefit.

Start 90 days before expiration if:

  • Your current authorization expires in 3 months
  • You've had any changes in lung function
  • You've experienced medication interruptions
  • Your insurance plan changed for the new year

Red flags that require immediate attention:

  • Declining FEV1 results
  • Increased exacerbation frequency
  • New contraindications or intolerances
  • Changes in smoking status
Tip: Set a calendar reminder 100 days before your expiration date. This gives you buffer time for scheduling appointments and gathering documentation.

Evidence Update: What Aetna Needs to See

Aetna's renewal criteria focus on two key outcomes: maintaining protective AAT levels and demonstrating clinical benefit through stable or improved lung function.

Required Lab Monitoring

Alpha-1 Antitrypsin Levels: Trough serum levels must be assessed before infusion. Clinical trials show Prolastin-C achieves mean trough levels of 16.9 ± 2.3 μM (antigenic assay) and 11.8 ± 2.2 μM (functional activity).

Pulmonary Function Testing: FEV1 measurements are critical. Aetna requires documentation of either:

  • Elevation of AAT levels above protective threshold
  • Reduction in FEV1 rate of decline

Clinical Monitoring Requirements

Parameter Frequency Documentation Needed
AAT trough levels Before each infusion cycle Lab results showing levels >11 μM
FEV1 testing Every 6-12 months Pulmonary function reports
COPD exacerbations Ongoing tracking Emergency visits, hospitalizations
Vital signs During infusions Infusion center records

Safety Monitoring: Hypersensitivity reactions must be tracked, as they occur in some patients and may require treatment modifications.

Renewal Packet: Must-Include Documents

Core Documentation Checklist

If Coverage Lapses: Bridge Options and Escalation

Immediate Steps for Coverage Gaps

  • Switching to preferred AAT products (Aralast, Zemaira)
  • Temporary dosing modifications
  • Enhanced supportive care during gaps
Note: Never discontinue AAT therapy without medical supervision. Treatment interruptions can lead to accelerated lung function decline.
