yes they did this to me to, my biopsy surgery for possible breast cancer, which it was stage 2 triple positive, after the biopsy was done, plus they denied the port surgery, the port I s needed for chemo, then they denied the chemo, stating it was all unnecessary, yes it was united health care also, I am paying for the 2 surgeries, but found another insurance that would cover chemo, it was difficult and pricey, but you have no other choices when you are dealing with life and death.
