How to appeal a Experimental / Investigational denial
This denial means the payer considers the service experimental or investigational under its medical policy, so it won't cover it, even when it's the appropriate care.
Common code: CARC 55 (experimental/investigational)Why payers issue it
- The payer's medical policy classifies the service as investigational
- Evidence supporting the service wasn't submitted
- Coding suggested an unproven indication
- The policy is out of date relative to current standards of care
What overturns it
- Submit peer-reviewed literature and clinical guidelines supporting the service for this indication
- Cite FDA status and any payer policy that does cover it
- Document why standard alternatives were inappropriate
- Request a peer-to-peer or medical-director review with the evidence
Worth appealing? Experimental denials are the hardest to win but the highest-dollar, a well-evidenced appeal overturns a real share, and the value of each recovered claim is large.
Common questions
How do I appeal a Experimental / Investigational denial?
This denial means the payer considers the service experimental or investigational under its medical policy, so it won't cover it, even when it's the appropriate care. To overturn it: submit peer-reviewed literature and clinical guidelines supporting the service for this indication; cite FDA status and any payer policy that does cover it; document why standard alternatives were inappropriate; request a peer-to-peer or medical-director review with the evidence. The key is matching the documentation to the payer's own rule for experimental / investigational denials.
Is a Experimental / Investigational denial worth appealing?
Experimental denials are the hardest to win but the highest-dollar, a well-evidenced appeal overturns a real share, and the value of each recovered claim is large. A no-risk recovery service makes it easy to find out, you only pay on what's actually recovered, so there's no cost to working the ones that are winnable.
