Breast reconstruction following breast cancer treatment
With a history of breast cancer, reconstruction is covered by insurance. To determine if you are a good candidate for breast implants, you will need to see a board certified plastic surgeon. He/she will need to evaluate the long term effects of the radiation to see if implant-only reconstruction is possible.
If you require a breast reconstruction, then your insurance should pay for it, but if you just want an augmentation in breasts that do not need reconstruction, then they probably will not.
