Voluntary Reporting of Data for Non-Outpatient Prospective Payment System (OPPS) Hospitals

Critical Access Hospitals (CAHs) and other non-OPPS hospitals may voluntarily submit data. The program provides a unique opportunity for hospitals to report outpatient quality data as a means to improve quality of care and performance. The registration for non-OPPS hospitals is the same as it is for OPPS hospitals. For more information on how to register, please visit QualityNet: How to Participate.

Hospitals that decide to participate agree to the same reporting requirements as the OPPS hospitals.

More information on data reporting may be found at under the Hospitals-Outpatient tile.
