FAQ

How long does Humana prior authorization take for Voxzogo in Illinois? Standard review takes up to 30 days. Expedited review (for urgent medical needs) is completed within 72 hours. Submit complete documentation to avoid delays.

What if Voxzogo is non-formulary on my Humana plan? Request a formulary exception using the Coverage Determination Form. Your doctor must provide a letter of medical necessity explaining why formulary alternatives aren't appropriate.

Can I request an expedited appeal if my child needs to start treatment immediately? Yes. If delaying treatment would seriously jeopardize your child's health or development, request expedited processing. Both internal appeals and external reviews can be expedited in Illinois.

Does step therapy apply to Voxzogo since there are no alternatives for achondroplasia? Typically no, since Voxzogo is the only FDA-approved pharmacologic treatment for achondroplasia. However, some plans may require documentation that supportive care alone is insufficient.

What happens if I miss the appeal deadline? Illinois allows 65 days for internal appeals and 30 days for external review. If you miss these deadlines, you may need to submit a new prior authorization request with additional clinical evidence.

How often does Voxzogo need reauthorization? Most payers, including Humana, require annual reauthorization. Start the renewal process 60-90 days before expiration, including updated growth data and confirmation that growth plates remain open.
