Zero vs limited cost-sharing for tribal members in 2027.

The short answer

Enrolled tribal members with household income from 100% to 300% of the poverty level ($15,960 to $47,880 for one person, $33,000 to $99,000 for a family of four in 2027) can get zero cost-sharing: no deductibles, copays or coinsurance on any metal level. At any other income, limited cost-sharing applies: no out-of-pocket costs at IHS, tribal and urban Indian programs or with their referral, and regular costs elsewhere.

Picking a metal level with zero cost-sharing.

Normally a bronze plan has the highest deductible and a gold plan the lowest. With zero cost-sharing there is no deductible on any metal. That changes the math: the plan with the lowest premium after your tax credit, often a bronze plan, can be the best value, as long as its network includes the doctors and hospitals you use.

If your income could land outside the 100% to 300% range, think about what happens then. With limited cost-sharing, a bronze plan's deductible applies outside Indian health programs, so a silver or gold plan may be safer if you use outside providers.

Questions people ask.

Does zero cost-sharing mean my health insurance is free?

No. It means no deductibles, copays or coinsurance for covered care. You still owe a monthly premium, which the premium tax credit or a tribal sponsorship program may lower or cover.

Do I need a referral with zero cost-sharing?

No. With zero cost-sharing you pay nothing at any in-network provider. With limited cost-sharing you need to go to an Indian health program or have its referral to pay nothing.

What if my income is above 300% of the poverty level?

You get limited cost-sharing: $0 at Indian health programs and with their referral, at any income, and normal plan costs elsewhere.
