BATON ROUGE, La. (AP) — Plans to shift more than 500,000 Louisiana Medicaid patients to new health plans by January will remain stalled.

The health department cannot negotiate terms with the four companies chosen to manage Medicaid patient care while legal disputes over the multibillion-dollar contract awards continue.

That was the decision issued Wednesday evening by Louisiana’s chief procurement officer Paula Tregre.

Two losing bidders are formally protesting the contract awards, accusing the health department of a biased bid review.

The health department wanted to continue moving ahead with new contracts, even as Tregre is determining whether state law was followed in the contract awards. The agency argued that delays could jeopardize services to Medicaid patients.

As she denied the department’s request, Tregre noted that agency leaders told lawmakers the legal disputes didn’t threaten services.
