Plan Types & Coverage Implications

Your Aetna plan type affects referral requirements and network restrictions for Elfabrio coverage:

Plan Type Network Rules Referral Required? Specialty Drug Access
HMO In-network only Yes, from PCP Covered if medically necessary; formulary restrictions apply
PPO In/out-of-network No Most flexibility; higher costs out-of-network
EPO In-network only Varies by plan Check specific benefit documents
Medicaid Managed Care In-network only Yes, from PCP Must comply with Illinois Medicaid regulations
Note: Aetna is no longer offering new individual off-exchange plans in Illinois as of 2025, though existing State of Illinois group plans remain available.

For Fabry disease treatment, all plan types typically require specialist involvement. HMO and Medicaid plans mandate PCP referrals, while PPO plans allow direct specialist access.

FAQ

How long does Aetna prior authorization take for Elfabrio in Illinois? Standard decisions take 30-45 days. Expedited appeals for urgent cases are decided within 72 hours.

What if Elfabrio is non-formulary on my plan? You can request a formulary exception with medical necessity documentation. Step therapy may be required first.

Can I request an expedited appeal in Illinois? Yes, if delay would seriously jeopardize your health. Mark the appeal as expedited and include physician justification.

Does step therapy apply if I've failed treatments outside Illinois? Yes, treatment history from any location counts. Provide documentation of prior therapies and outcomes.

What happens if I miss the 30-day external review deadline? Illinois strictly enforces this deadline. Contact the Department of Insurance immediately if you believe you have grounds for an extension.

Can I appeal if my specialist isn't in-network? For HMO/EPO plans, you typically need in-network specialists. PPO plans allow out-of-network access with higher costs.

From Our Advocates: "We've seen the strongest Elfabrio approvals when providers submit quantitative enzyme levels with reference ranges rather than just summary statements, plus detailed clinical documentation showing organ involvement. Aetna reviewers want explicit lab results, not generalizations. This comprehensive approach significantly improves approval rates, especially on appeal."
