ICE Health Service Corps (IHSC) supports ICE’s mission to protect national security and public safety by upholding healthcare standards across ICE-owned and contracted facilities and ensuring detained aliens receive required healthcare. IHSC does this by working with community-based healthcare providers for emergency and specialty care services.

 

Who We Are:

Acentra Health combines public sector knowledge, clinical expertise, and technological ingenuity to modernize administrative healthcare processes for state, federal, and commercial partners for their priority populations.

What We Do:

Acentra Health is currently under contract to provision a claims processing system for IHSC. In this role, Acentra Health is establishing technical environments, setting up data services, software configurations, recruiting, and training staff to support the contract.

News & Updates


Oct 12, 2026, is the go-live launch for claim processing services for electronic data interchange (EDI) and direct data entry (DDE) from the provider portal.

For FY 2026 claims with dates of service from Oct. 1, 2025, through Sept. 30, 2026, IHSC will adjudicate EDI or DDE claims based on the adjudication decision. Providers must be enrolled and approved to receive EFT payments.

FY 2025 and FY 2027 EDI and DDE claim adjudication exceptions:

  • IHSC will temporarily suspend adjudication for claims with FY 2025 dates of service, Oct. 1, 2024, through Sept. 30, 2025, until the government reallocates FY 2025 funds for EFT processing. Providers must be enrolled and approved.
  • IHSC will temporarily suspend adjudication for claims with FY 2027 dates of service, beginning on or after Oct. 1, 2026, until the government allocates FY 2027 funds for EFT processing. This is normal at the start of the new federal fiscal year. Providers must be enrolled and approved.
  • The filing periods for FY 2023 and FY 2024 have closed for dates of service Oct. 1, 2022 through Sept 30, 2024. The clearinghouse will reject claims submitted for FY 2023 and FY 2024.

Please monitor this website and the IHSC Managed Care web page for updates. We encourage providers to complete enrollment before claims submission functionality becomes available.

IHSC’s new claims processing services via Acentra Health are fully electronic.
