FAQ
What does "Out of network" mean on a denial letter?+
The provider does not have a contract with your insurer, so the claim was paid at a lower rate or not at all.
How long do I have to appeal?+
180 days from the date of denial for ERISA group plans and ACA marketplace plans. 60 days for Medicare Advantage. Check the denial letter for your specific deadline.
What is the success rate for this kind of appeal?+
Outcomes vary, but medical-necessity and step-therapy appeals overturn at meaningful rates when the appeal cites the insurer's own policy and the chart documents the required criteria.
