SEATTLE (AP) – Many Washington residents with diabetes will have an easier time affording insulin this year, as a law imposes a $100 cap on patient copayments.

The law applies to any health-care plan issued or renewed after Jan. 1 that covers insulin drugs. It includes language to protect people who have “high deductible” insurance from paying more than $100 per 30-day supply, the Seattle Times reported.

About 686,000 people in Washington state have diabetes, and 226,300 rely on insulin. In 2017, diabetes was the seventh leading cause of death in the state, according to the state Department of Health.

The law, sponsored by Sen. Karen Keiser, D-Des Moines, was approved by the Legislature in March to ease a crisis that can lead to medical complications. Studies show an estimated-one quarter of patients ration the medication because of cost or difficulty obtaining steady supplies.

Diabetes is a potential risk factor for COVID-19 complications.
