Indian Health Service (IHS), 638s, Medicare, credentialing, quality, compliance, and oversight.
Why this matters
Healthcare is not one system. It can involve IHS, 638 organizations, Medicare, Medicaid, state licensing boards, federal oversight, and internal boards.
IHS vs 638
IHS facilities are federally operated.
638 facilities are tribally operated under federal self-determination authority.
This can create fragmented oversight: internal boards, state licensing boards, federal payers like CMS (which certifies and surveys facilities for Medicare/Medicaid — not an accreditation), accrediting bodies like the Joint Commission, and law enforcement may all have separate roles.
Medicare and billing basics
Providers generally do not simply charge whatever they want and get paid. Reimbursement often depends on coding, documentation, medical necessity, payer rules, and audits.
Was the service medically necessary, documented, coded correctly, and monitored?Credentialing and privileging
Credentialing verifies education, license, training, certification, malpractice history, sanctions, background, and references.
Privileging decides what services a provider may perform at a facility.
