Texas Attorney General Ken Paxton has sued Eli Lilly, alleging the drugmaker offered illegal incentives to providers, leading to millions in improper Medicaid claims.

Paxton's office said the company supplied free nurses to help care for patients who received its drugs, as well as administrative support services that helped providers process insurance claims.

"Big Pharma compromised medical decision-making by engaging in an illegal kickback scheme," Texas Attorney General Ken Paxton said.
