I know of a situation with an ovarian cyst just as described above. Two ER visits over a couple years. Then the final one was the cyst burst, twisted the ovary and emergency surgery was required. The pain is like appendicitis, not a joke. I hope they prevail if they appeal.
Per the link above . . .
Brittany Cloyd lost her first appeal, but she refused to take no for an answer. So she sent Anthem a second appeal with documentation and a rebuke.
"I'm not sure how one knows if they're bleeding internally," she wrote. "But I hope that it's apparent … perpetuating scare tactics could certainly convince patients not to go the emergency room. I foresee an onslaught of wrongful death suits in Anthem's future."
Cloyd said Anthem then paid her entire $12,596 ER bill.
