In her dual roles at the hospital and as the director of women’s services for HealthNet, Robinson says she had a unique vantage point. She said other physicians approached her with similar concerns about patient care.

“[I learned of] people that should have certain monitoring during their pregnancies because of their risk factors – whether it’s high blood pressure, whether it’s diabetes – and that monitoring had not taken place," Robinson said. “There was little to no physician involvement in the obstetrical care of these high risk patients."

The doctor says she tried to appeal to her bosses numerous times and pushed for more physician involvement. But when she tried to do that, Robinson says she was first told to keep quiet and then fired in the summer of 2013.

“They knew it was wrong. They knew that they were preying upon a vulnerable population,” Robinson said. “They just felt that they could be sacrificed. Why? Is the almighty dollar that important to them?”

When asked why Robinson was fired, a spokesperson for IU Health told America Tonight: "Dr. Robinson and Indiana University Health had a contractual relationship that allowed either party to terminate the contract with notice. Indiana University Health exercised that provision.”

All three organizations at the center of lawsuit declined our requests for interviews, but IU Health and HealthNet, provided written statements. (See the full statesments below.) Both organizations vigorously denied the allegations and said they were fully complying with government requests for documents and medical records. Because of the ongoing litigation and patient privacy rights, they couldn't share specifics.

America Tonight tried to verify Robinson’s allegations by talking to numerous other doctors who worked in the system, but none were willing to speak on the record.

As a federal False Claims Act lawsuit, the government has the opportunity to take over the case. Both the federal and state governments are still investigating the allegations and told America Tonight that they have not yet decided if they will intervene.
