Cigna will offer $500 to members who switch to less costly biosimilar drug alternatives for inflammatory conditions, including arthritis and Crohn's disease.
The company said in a June statement that drugs like Remicade, used to treat conditions like ulcerative colitis, can cost roughly $30,000 annually.
"While life-saving and life-changing, this presents a significant challenge for health plans and can be financially devastating for patients," the statement said.
Biosimilars are clinically equivalent alternatives to biologics like Remicade, and can reduce drug spending by up to $375 billion over the next decade, according to the statement.
