Heaps retired from UCLA Health in 2018 following an investigation into allegations of sexual misconduct and billing irregularities. Since his arrest, dozens more female patients have come forward citing similar allegations, and multiple lawsuits have been filed against him accusing him of misconduct date back as far as 1989.

Heaps worked at UCLA Health for nearly 30 years. According to the Los Angeles Times, the UC Board of Regents paid $2.25 million to a patient who claimed that Heaps sexually assaulted her during an appointment in early 2018. In March, UCLA paid $1.3 million to a nurse practitioner to settle a complaint that Heaps had sexually harassed her and retaliated against her for taking part in the sexual misconduct investigation against him, the Times reports.

Last December, attorneys representing more than 45 patients accused UCLA of dragging its feet on the investigation into Heaps and allowed him to continue to treat patients even after school officials found evidence he had committed sexual assault .
