New Facility / Services

All Wisconsin, Medicare-certified, hospitals, including psychiatric hospitals, and freestanding ambulatory surgery centers (FASC) are required to report inpatient and outpatient discharge data to the Wisconsin Hospital Association Information Center (WHAIC) each quarter.

WHAIC collects data pursuant to Chapter 153 of the State Statutes and subject to all terms and conditions as described in ss. DHS 120. Failure to comply with the reporting requirements regardless if the facility uses a vendor or not may result in financial penalties to the organization.

Submitting Data and Training
- Data Submitters and Users are required to register to the WIpop Application. Instructions to Register.
- Review the WIpop Roles document prior to registration
- Contact WHAIC Staff to review the manual and data submission schedule.
Plan accordingly: Hospitals and ASCs are required to use a modified 837 claims file format as outlined in the Data Submitters WIPop 837 Companion Guide and Technical Specifications Manual. Most facilities require the expertise of their EHR/billing vendor, or IT Staff, to develop a modified claims file to submit data. The WHAIC Companion and Technical Specification Guide follows the national ANSI 837 standards and provides specifications for the submission of discharge data to the WHAIC. For more information see /submitters/WIpop/.
