American Indians & Medicare
Do American Indians pay Medicare costs at IHS or tribal facilities?
Last reviewed: · Big Sioux Benefits Data Desk
No, at an IHS or tribal facility you will not be billed Medicare's deductible or coinsurance, but the reason matters: the facility waives those amounts, Medicare does not exempt you from them. The CMS Medicare Claims Processing Manual (Chapter 19, Indian Health Services) instructs that "IHS physicians and practitioners shall not collect the deductible or coinsurance from the beneficiary." Medicare still applies its cost sharing to the claim; your Indian health care provider then absorbs it at the point of service.
The qualifier is where people get hurt: a provider waiver does not travel with you. At a hospital, specialist, imaging center, or pharmacy outside the I/T/U system, which is where referrals for surgery and specialty care usually go, you owe exactly what any other Medicare beneficiary owes: the Part B deductible ($283 in 2026), 20% Part B coinsurance, and Part A cost sharing if admitted. There is no American Indian or Alaska Native exemption from Medicare premiums, deductibles, coinsurance, Part D costs, or IRMAA. The genuine AI/AN cost-sharing exemptions people have heard of are Medicaid and CHIP rules (42 C.F.R. § 447.56) and Marketplace rules, real protections, but not Medicare ones.
Where you owe what
| Setting | What you pay with Medicare |
|---|---|
| IHS or tribal (I/T/U) facility | Nothing: the facility waives Medicare's deductible and coinsurance |
| I/T/U pharmacy | Nothing for covered drugs dispensed there |
| Outside hospital, specialist, or pharmacy | Normal Medicare cost sharing: deductibles, coinsurance, copays |
| Anywhere, if you have QMB (Medicare Savings Program) | Providers are barred from billing you Medicare deductibles and coinsurance |
That last row is the practical fix. If your income is limited, a Medicare Savings Program, QMB in particular, extends real cost-sharing protection beyond the clinic walls, pays the Part B premium, and can erase a Part B late penalty; South Dakota's 2026 limits are $1,816 monthly income and $9,950 in resources for an individual (SD DSS brochure, May 2026). Extra Help does the same for drug costs. Both are covered, alongside the Marketplace-versus-Medicare distinction, in American Indians and Medicare in South Dakota. Your facility's benefits coordinator or SHIINE can check your eligibility for free.

Related questions
Is there an American Indian exemption from the Medicare Part B premium?
No. Tribal membership does not change any Medicare premium, deductible, coinsurance amount, or IRMAA surcharge. The Part B premium can be paid for you by a Medicare Savings Program if you qualify, and some tribes sponsor premiums for members under the general third-party payer rule. Ask your tribal benefits coordinator what your tribe offers.
Why did I owe nothing at my clinic but get a bill from the hospital in town?
Because the zero cost at your IHS or tribal clinic is a waiver by that facility, not a Medicare exemption. The outside hospital bills Medicare cost sharing normally. If you are enrolled in QMB, show the provider your QMB status, federal law bars billing you Medicare deductibles and coinsurance, and if you may qualify, apply through South Dakota DSS.
