AUSTIN — Texas’ health department will investigate billing irregularities and end its contracts with an anti-abortion group that failed to provide health care to the number of women it promised the state it could serve. The Texas Health and Human Services Commission announced Friday that it was terminating two contracts with the Heidi Group for the state’s Family Planning Program and Healthy Texas Women, which offer free and low-cost family planning services to low-income women. The Heidi Group will also have to repay the commission $29,431, and the Office of the Inspector General will determine if it owes an additional $1.1 million. The Heidi Group served only 3,300 clients out of nearly 70,000 it told the state it would cover in fiscal year 2017, according to data from the commission. Despite this, the group was awarded new contracts for the 2019 fiscal year, which began Sept. 1. But during a regular review, spokeswoman Carrie Williams said the agency decided to end the partnership, effective Dec. 11. “We worked with the Heidi Group over time on its performance, and we have determined that the Heidi Group is unable to meet the standards of a successful contractor with us,” Williams wrote Friday in an email. “Contract termination was in the best interest of the state and the clients we serve.” She said the department had tried to help the Heidi Group through site visits and reviews, but it continued to fall short in the areas of contract compliance, service administration, and financial and administrative management.
