I am the medical biller for a Home Health Agency located in Ohio. Has anyone working in home health had success billing Aetna Advantra after 1/1/20? I have sent my claims using type of bill 321, 322, 323, and 324, just as I always have. All of my claims are being denied and when I contacted them, I was told that it's because of the type of bill. Do they now need to be billed using a 329 like a Medicare Final Bill? Also, we used to bill by month. Do the claims now need to be sent episodically? Our agency has not been paid on any Advantra claims since 1/1/20. Any help would be appreciated! Thank you!
