You need to send a corrected claim billed the way Humana wants it.
Humana had a revision in June 2022 to its Radiation Therapy Treatment Management billing and coding policy. You can find the policy at this link to make sure that your corrected claim is set up the way Humana wants it:
https://www.humana.com/provider/medical-resources/claims-payments/claims-payment-policies
(The link goes to all of Humana's Claims Payment Policies - search for the Radiation Treatment Management one. If you scroll down it's about half way down the list.)
There was another thread discussing it here recently (after Humana's policy changed & we were all caught off guard for a bit) You might be able to pick up some helpful hints if you look at that too:
