The IHS does not have a health plan or a set package of benefits. Instead, they offer access to programs of care. They are generally limited to primary care physician care only and other limited services. The services may be sufficient to address some medical conditions, and they may not manage others. Without Medicare and supplemental coverage, Medicare beneficiaries are exposed to Medicare’s out-of-pocket cost-sharing requirements unless receiving services from Indian Health Service, tribal entities, or Urban Indian Health Programs or through a Purchased/Referred Care referral.
