insurance issue

[Srikalakm]

hi guys,

My mother was diagnosed with her2+ve braa we ya cancer stage 4.

doctor recommended the below medications :

Paclitaxel + cyclophosphamide + phesgo+ zolodronic acid .

I have corporate insurance in new India insurance with mediassist.

These people are not approving phesgo which is targeted therapy telling that it is as immunotherapy instead of targeted .

and immunotherapy are not covered in insurance policy .

but our doctor is saying it’s a targeted not immunotherapy drug and without that drug we won’t be able to provide quality of life to patient and her treatment will be incomplete according to NCCN guidelines.

but our insurance company is rejecting the insurance .

anyone faced such issues with this targeted drugs and how did u resolve it ?
