Overview
Key components
Provider-Based Attestation
Hospitals must annually attest to CMS that provider-based departments continue to meet all applicable criteria. The attestation process involves documenting clinical integration, financial integration, provider-based appearance, and administrative integration — all of which must be maintained continuously.
Patient Notification
Medicare requires that patients be notified — and acknowledge — that they are receiving services at a hospital outpatient department and will be responsible for hospital outpatient cost-sharing (which may differ from physician office cost-sharing). This notification must be documented in the patient's record for every encounter.
Dual Billing Coordination
Provider-based billing generates two claims per encounter: a UB-04 facility claim billing the hospital's OPPS facility fee, and a CMS-1500 professional claim billing the treating physician's professional fee. These claims must be clinically consistent but follow different billing frameworks — coordination failures result in coordinated denials.
On-Campus vs. Off-Campus Determination
On-campus HOPDs (same campus as main hospital) and grandfathered off-campus HOPDs (established before November 2, 2015) bill under OPPS. Non-grandfathered off-campus HOPDs bill at site-neutral PFS rates. Correctly classifying each HOPD location — and billing accordingly — is a foundational compliance requirement.
APC Optimization
HOPD claims are reimbursed under OPPS using APCs. Comprehensive APCs package multiple services into a single payment. Ensuring that HOPD coding correctly captures all separately payable services — and avoids packaging errors — is central to OPPS revenue optimization.

Key billing & regulatory reference
Billing Dimension
Detail & AnnexMed Approach
Facility Claim
UB-04; TOB 13X (HOPD); OPPS/APC reimbursement for qualifying HOPDs
Professional Claim
CMS-1500; physician PFS rate; modifier 26 (professional component) where applicable
On-Campus HOPD

Grandfathered Off-Campus
Established before Nov 2, 2015 — transitional payment rate (50% of full OPPS by 2020+)
MOON Notice
Required for Medicare/Medicaid patients in observation >24 hours; delivered within 36 hours of observation start
Non-Grandfathered Off-Campus
Established after Nov 2, 2015 — site-neutral PFS rate; no facility fee advantage
Patient Notification
Required before or at time of service — failure to notify is a compliance violation, not just billing error
Comprehensive APCs
C-APCs package all surgical/procedure services — understanding APC packaging critical for HOPD revenue
Top Denial Types
Provider-based status not established, patient notification missing, site-neutral misclassification, APC packaging error
