AFLAC claims

The claims people at AFLAC are being real jerks. I have the AFLAC Cancer policy, and for a year now, I have been struggling with them to pay my claims for dexamethasone as chemo. Their policy states that dex, when taken orally at 40mg, qualifies as chemo. However, they have been denying the claim all this time. They pay it as anti-nausea meds. I have spoken to them and written to them. My hem/onc has written to them. They have told me to change the way I submit the claims, and that would resolve the problem. Nothing has worked. I’m still getting the runaround! If you have the AFLAC Cancer policy, and you have successfully filed a claim for dexamethasone as chemo, please let me know. This is beginning to smell like fraud to me!
