Medicare tightens off-campus billing: separate IDs, compliance attestations required

What it does

This bill requires off-campus outpatient departments of hospitals and medical providers to obtain a separate Medicare billing identifier and submit attestations that they comply with federal regulations governing provider-based departments. Starting January 1, 2026, Medicare will not pay for services from these off-campus departments unless they meet these new identification and compliance-verification requirements. The bill aims to prevent billing fraud and ensure off-campus departments are legitimately provider-based rather than independent facilities billing under a hospital's credentials.

Why we flagged it

The bill's operative mechanism is a payment condition tied to compliance verification and separate identification for off-campus departments. It is a regulatory enforcement and transparency measure, not a subsidy, carve-out, or deregulation.

What the text implies

• Hospitals with off-campus departments may face significant compliance costs and administrative burden to obtain separate identifiers and submit attestations, potentially delaying or complicating expansion of outpatient services.
• The Secretary has broad discretion to define the attestation process and compliance review methods (site visits, remote audits, etc.), creating potential for inconsistent enforcement across regions.
• Smaller or rural providers with limited off-campus operations may face disproportionate compliance costs relative to large health systems with established compliance infrastructure.
• The 2030 HHS OIG report requirement suggests Congress expects implementation challenges; early enforcement may reveal gaps in the attestation process or CMS's ability to verify compliance at scale.

Who it affects

Ordinary people benefit from reduced billing fraud and clearer accountability for off-campus departments that may have been improperly billing under hospital credentials. The compliance requirement and separate identifier create transparency and prevent cost-shifting. The administrative burden falls on providers, not patients.
