This week, California became the 29th state to approve legislation capping the costs of insulin for Californians on private state-regulated health plans. The American Diabetes Association® (ADA) applauds Governor Gavin Newsom’s decision to sign Senate Bill 40, addressing insulin affordability by limiting cost-sharing for insulin to $35 for a 30-day supply.
In California, approximately 3.5 million adults have diagnosed diabetes. And while not all use insulin, those who do rely on it to survive.
“For far too long, many Americans with diabetes have made the difficult decision to ration this lifesaving medication to pay for other necessities, such as groceries or rent. This legislation will provide much-needed financial relief for people living with insulin-dependent diabetes,” said Christine Fallabel, MPH, the ADA’s state government affairs director. “The ADA and our community of Diabetes Advocates continue to push for legislation across the nation to make insulin accessible for all who need it to live.”
Effective January 1, 2026, large group insurers will be required to cap insulin copayments at $35 for a 30-day supply and to ensure at least one insulin for a given drug type in all forms and concentrations be on the prescription drug formulary. Individual or small group health care insurers will need to cap copayments starting on January 1, 2027.
This makes Senate Bill 40 one of the strongest patient protection laws in the country for people living with diabetes.
The ADA thanks Senator Scott Wiener for authoring this important legislation and admires his commitment to insulin affordability for those who need it most.
“If we believe healthcare is a right — as we should — we have to make it affordable for everyone. This law ensures no family will be forced to choose between buying insulin and putting food on the table in California again,” said Senator Wiener. “Working people are building the future of California, and we must make it affordable for them to live a healthy and thriving life here. I’m grateful that the Governor signed this bill into law, at a time when affordable healthcare is under attack across the country.”
The estimated diabetes impact in California:
- Adults diagnosed with diabetes: 3.5 million or 10.5% of the adult population
- New diagnoses in adults every year: 231,000
- Annual cost of diagnosed diabetes in California: $47.5 billion
- Direct medical expenses for diagnosed diabetes: $34.1 billion in 2022
- Indirect costs from lost productivity due to diabetes: $13.4 billion in 2022
