In the Calendar Year 2026 Medicare Hospital Outpatient Prospective Payment System (OPPS) Final Rule, the Centers for Medicare & Medicaid Services (CMS) added new Hospital Price Transparency requirements and will begin enforcement on April 1.
Hospitals must update the machine-readable file posted on their website to include new allowed amount data elements (median, 10th percentile, 90th percentile, and count), their organizational National Provider Identifier (NPI), and an attestation from a senior official confirming the information is accurate and complete. Hospitals that do not comply may receive warning notices, be required to submit corrective action plans, or face civil monetary penalties that may be publicly reported.
CMS maintains tools and resources to help hospitals in meet machine-readable file requirements.
