019-- Pain Mgmt-Aetna Denials??

Wanted to see if anyone has any insight or experience with Aetna denying 019-- codes for pain management, denying for medical necessity.
Our office does anesthesia & pain management billing.

We are able to submit for reconsideration & appeal, to get a very small amount of them reprocessed & paid, but most remain denied.

This seems to only be an issue with Aetna. There are some denials from Humana, but we've been able to appeal and get them paid.

Does anyone have any insight? Not sure what others are doing with these denials.

Thanks.
