Just got off the phone with both the RO office and Humana. Have to get a pre-authorization letter to Humana before the visit so they can approve him (even though is he part of the Humana Network already - just not my local network). The insurance company won't let me do the claim - it has to be started by the doctor, and he already has a full schedule today and can't do it today, so looks like I either chance it and keep the appointment and risk having to pay $500 (what the biller said the charges would be) for it instead of the $15 copay or reschedule for at least one more week out - which makes the consult appt 6 weeks out from surgery. I don't know what time frame you have to start radiation for it to be effective - but I imagine that is approaching rather quickly.
This is all so frustrating! And, since my surgeon isn't recommending radiation at all - he probably wouldn't be willing to write the letter saying I need to go to the CCC (at least for the consult).
