Faced with rising anger on drug prices, Cigna plans to reduce insulin costs to $25 a month for many patients

Responding to massive public pressure about the high price of life-saving insulin for people with diabetes, the insurance giant Cigna and its drug benefit arm, Express Scripts, aim to reduce the monthly cost of insulin from $40, on average, to $25 for many patients.

For many, the reduction in out-of-pocket cost could be much greater. Depending on how a health plan is designed, some patients now pay, on average, $100 a month. And some patients are hit by costs of hundreds of dollars in a single month.
